Setting the default button directly on addbutton. I tried both in aspx and in code to set the defaultbutton to the custom control and implement the IButton interface, but that was also fruitless.
I have a GridView control on a page with a Panel that has a DefaultButton. I am trying to get the "Update" button to work with the Enter key when a user edits a row. It works fine with the mouse. When I click on "Update", the row reverts back to View mode and the updated value is shown.
When the GridView is in the Panel, the Panel's default button (which submits the page) fires when I press Enter, before the RowCommand is even handled, and the update is lost.
When the GridView is not in the Panel, some other seemingly random button in the Panel fires, but not the "Update" button in my row's EditItemTemplate. Specifically, there is a CalendarExtender on the page, and the extender's popup button fires. Totally not what I want.
How can I get this to behave correctly?
Here is the structure of my mark-up code:
<asp:Panel ID="Panel1" runat="server" DefaultButton="btnSubmit"> <!--Form with controls--> <asp:ImageButton ID="btnWSPODateCal" runat="server" /> <!--this button fires when I press enter while editing a grid row:--> <ajaxToolkit:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="tbPODate" PopupButtonID="btnWSPODateCal" /> <!--more controls--> <div class="button_row"> <asp:ImageButton ID="btnCancel" runat="server" /> <asp:ImageButton ID="btnSubmit" OnClick="btnSubmit_Click" /> </div> </asp:Panel> <asp:GridView runat="server"> <Columns> <asp:TemplateField> <EditItemTemplate> <asp:ImageButton CommandName="MyUpdate" ID="btnSubmitRow" runat="server" CommandArgument="<%# ((GridViewRow) Container).DataItemIndex %>" />
On my page i have a set of control containing parts of a form, like textboxes, checkboxes etc. I use those parts to build controls that I use in pages. For example:
What I then want to do is to set the behavior of Panel1 to have a default button in the addbutton control. I have tried setting the Panel 1 default button to the botton in formbutonline like this: Panel1.DefaultButton = addButton.Button.UniqueID; in Page_load, but that does not work because .net throws this error: The DefaultButton of 'Panel1' must be the ID of a control of type IButtonControl. Now the button is public, so that should be ok. I have also tried ID and ClientID, with te same results. I have also tried to implement the IbuttonControl in PartFormButtonLine and map the implemented functions to the button
functions, which, as expected did not work. (Panel1.DefaultButton = addButton.ID) The problem as far as I can tell is that I cant seem to set the
of the container div to the correct value, onkeypress="javascript:return WebForm_FireDefaultButton(event, 'MainContent_UserAddToList_addButton_Button')" Everything else works, this is the last thing that needs to be fixed.. Idealy i want to fix this in the PartFormButtonLine file, as that would be better for reuse {update: removed quite abit of clutter in the ascx snippets}
to have back fired on me a bit (See http://www.vbforums.com/showthread.php?t=620703). I have some other buttons on the page that I attach javascript to, e.g.:
Code: <script type="text/javascript"> function Pick12() { var PopupWindow = null;
[code]....
Basically I use javascript to pop open a window with a datepicker which they use to populate a textbox on the main page with a date. However, if I set a defaultbutton, when i click one of these buttons the popup window flashes to the front of the screen and then the main browser window gets focus over it. Without default button the popup stays on top.
I have several text boxes in an asp:Panel. When the user hits Enter from any of those boxes, I want the form to submit as if they've clicked btnAddTag. (When the cursor is not in those boxes, I have a different default submit button.)
I have a page where a user can type a From & To address, which brings up a new window w/ directions. In order to bring up the page in a new window, I'm using an HTML Button (not a Button Control).
The problem I'm having is when a user hits the enter key. I tried setting the default button for the pane, but quickly learned this isn't allowed.
I added some Javascript to capture when the enter key is hit, but this isn't working right on Firefox & the iPhone Mobile Safari browser.Is there a standard way to make an HTML Button the default button of a panel?
Ideally, I could use a Button Control, prevent it from going to the server & only execute the javascript. Is this possible?
I have created a custom web control to act as a button with an image. I would like to be able to set this as the target of the DefaultButton parameter of an ASP.NET Panel control. I have implemented the IButton interface, and no error is generated when loading the page using the control. However, when I press enter in a textbox within that panel, the Click event of the control is not raised. When I replace my control with a standard ASP.NET button, everything works fine.I have a test page with a panel containing a textbox, an instance of my custom button, and a standard asp.net button. The buttons are wired to an event handler which will change the textbox to the ID of the caller.When DefaultButton of the panel is set to the ASP.NET button, hitting enter in the next box works correctly - the page posts back, and the text box is populated with the name of the standard button. When DefaultButton of the panel is set to my button, hitting enter in the textbox causes the page to postback, but the Click event is not fired. Clicking the button manually works correctly.Does anyone know what I have to add to my custom control to make it handle the event coming from the Panel control? I'm looking using Reflector at the source code for Button, but cannot identify what is enabling this behaviour.I have posted the source of the control below, and the relevant source of the test page.Control Source:
public class NewButton : WebControl, IPostBackEventHandler, IButtonControl { public NewButton() : base(HtmlTextWriterTag.A) { }
I have a panel, with several textboxes and an ImageButton inside of it. One of the textboxes has a MaskedEditExtender and a MaskedEditValidator associated with it. When I hit enter from any other textbox besides the one with the MaskedEditValidator the defaultbutton that is defined in the Panel's DefaultButton property handles the enter key.However, when I am in the textbox with the MaskedEditValidator, the first button on the form is receiving the enter key. Now, if I take the MaskedEditExtender off of the page, and just leave the MaskedEditExtender, everything behaves as it should.Can anyone offer any insight into how I may get this to work properly, or is this a known bug?I tried searching the forums and found a similar post, but no conclusion was ever reached.
I have a search panel in my master page, which seems to be getting called when typing in another panel and hitting enter, even though the panel has a different defaultButton. The weird thing is the second and third panels work well, which ever one I put at the top calls the search button.
I am using ASP.NET Panel to set Default Button for some Controls like TextBox but it seems to not work due to AJAX Control Toolkit's AutoCompleteExtender.
I have a panel control in gridview's template. I need to hide/unhide panel in javascript function, for that i need to pass panel's id to the javascript. The problem is that all panels have the same id in gridview, so I need to set unique id to each panel.
I tried to do:
<asp:Panel id= "Panel_<%# Eval("ID")%>" and some other variations but always get an error.
The panel contains some other controls, I need it to be server side because I need to set at code-behind (after checking if user is authenticated) What can I do? p.s. It doesn't have to be Panel, any other control that I can find with Findcontrol and can hold other controls.
Update:
I set the the js event in code behind: protected void gvw_RowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { if (UserIsAuthenticated) { HyperLink title = e.Row.FindControl("lnkTitle") as HyperLink; Panel panel = e.Row.FindControl("panel") as Panel; title.Attributes.Add("onmouseover", "ShowHidePanel(" + panel.ClientID +")"); //All get the same id!!! } } }
I'm having a bit of an issue in my ASP.Net application moving focus from a textbox in one user control to a text box in the next user control on the page after postback. I've searched high and low over the last several days to find a solution but, for whatever reason, have been unable to do so.
I have a page that has user controls loaded dynamically to allow a user to enter data.The number and type of user controls loaded to the page is determined at run time based on a database query.It is possible than many controls of the same type can be loaded. Each user control has its own update panel. Within the update panel of each control is a regular asp panel. Inside of the regular panel there are at least 2 server controls (any other controls that may exist in the user control are not affected by this issue) - a text box and a button.The defaultbutton property of the regular panel is set to the ID of the button within the user control. The desired behavior is to allow the user to enter data into the textbox on one user control hit enter to save the data on that user control the application will set focus to the textbox of the next user control on the page after the data from the "current" user control has been saved. Other considerations;
The application uses master pages. We make extensive use of ajax and the ajaxtoolkit in the application. I am using Visual Studio 2010 and .Net 4 The issue - when first entering the page, one can enter data into the first textbox and press the enter key. Data from "current" user control is correctly saved and focus is correctly moved to the next user control on the page.
Data can be entered into the textbox of "new" user control and when the enter key is pressed, the data is correctly save. The focus appears to move correctly to the next user control on the page.Data cannot be entered into the textbox of the control. Pressing the enter key will not save the data (because none was entered) but the focus will move to the textbox of the next user control on the page.
Data can be entered into the textbox of the user control. When the enter key is pressed, the data is correctly saved and the focus appears to move correctly to the textbox of the next control on the pageBasically, steps 3 and 4 are repeated until the end of the user controls on the page, alternating between being able to enter data and not. Other items of note When one is able to enter data into the textbox of a user control, one can correctly tab through the textboxes of each user control until the end of the page When one is not able to enter data into the textbox of a user control, pressing the tab key will take the focus to the address bar of the browser.
I created a much simplified example of the scenario described above and was able to consistently reproduce the "bad" focus behavior. All of the ajax toolkit controls and code where stripped out of the sample to rule the toolkit out as a cause. The behavior still occurs without the toolkit.
I am including the code for default.aspx and WebUserControl1.ascx.
The panel has an OK-Button to dispose the popup. It is also possible to click Return to dispose the popup, because the panel has the property DefaultButton="okBtn".
But this only works when the popup has the focus, which is not so from the start. How do I get the popup panel to have the focus when it shows? I would like to use jQuery.
I have a page with user controls getting dynamically added. Inside some of these user controls there are form elements, either simple <input> tags or complex third party controls (Telerik RadDatePicker for example) (technical details at end).
These controls are currently being identified as part of the same form based on a ValidationGroup string setting. My question is how can I get these form elements to submit on Enter together and raise the right postback event?
I cannot use the DefaultButton panel property because I don't have the id of the submit button available within the controls server-side. I think I might be able to use jquery clientside like this:
But I don't know how to do that for the third party controls.
Further technical details: Each form element is in a separate DNN module. Inter-module communication can be used to pass around data server side which results in multiple modules working together as part of a single logical form on a page.
I am using a master page and web content forms in my project. I have a panel on my web content page which opens a popup window using window.open. When opening the popup window, I disable the panel on the web content form.
When I close the popup window, I want the panel to be enabled. I am trying to do this using javascript, but I am not sure how can I set the enable property of the panel to true using javascript.
I have an update panel which has 2 set of controls each in their own separate panels. We can select either panel by a checkbox list and they become visible. Now I am trying to set a value by javascript in the panel that becomes visible on my checkbox click but the problem is that I cant access the controls through javascript as they are not rendered on page as visibility is false.
I cant find the controls inside the page source even though they are visible on page so javascript cannot access them. Is there any way other than doing a postback and setting them visible to access them via javascript?
I need to do a partial update of a page using an UpdatePanel but I want to throw it using onkeydown. Is there a way to do this by creating a custome asyncpostback trigger.
On the other hand i have a MultiView that contains Several view that in turn itself contains several controls .
In multiview we have to set ActiveViewIndex for the view which we want to see.
That same thing can be done through Panel containing another seleral panel's and setting its Visible property to True/False accordingly.
Is seems Multiview is just using this Visible property internally to render controls .Since other views (whose Index is not set to be active Index) are processed on the server for its Whole life cycle(I am confused here..whether i am right or not) .Same thing perhaps happen when we use a Panel insteed and use Visible=True/False. So, what is the difference between MultiView and Panel taking this scenario ?
I have a createuserwizard where people input their information. When I hit enter after typing in the data in the form it returns me to the homepage. How do I set the default button for the createuserwizard so that it goes to the next step rather then back to my homepage.
I'm not sure if it has to do with the fact that I have a defaultbutton set in a form in the masterpage and that defaultbutton overides the other pages defualtbutton....
I have a search textbox and a search submit button on my page. I have used the following code to allow the keyboard "Return" button to effectively "click" the search submit button without the user having a reach for their mouse.
[Code]....
However, I would like to hide the search button, since it clutters the page a little, and everyone is likely to run the search by pressing the Return key anyway. But the search ceases to run when the button is set to Visible="false", even if Enabled="true"!!Is there any way to hide the button whilst still allowing the search to work?
I have a text box and many buttons. When user is in some text box and presses the "enter" key then specific button click event is raised. I read on the internet that there are some problems with the "enter" key and I tried few solutions but still it always enters that button event (that button is the first button in the page).
I tried creating a button which does nothing and writing this in the page_load:
I have listview where every item has a textbox and next to it a button if you want to update the item. I want that every textbox default button(pressing enter) is the one right next to it. So i have a panel(pnlInput) surrounding the textbox(txtQuantity) and the button (btnCart). If i do nothing in code behind the default button for every textbox is the button of the item that was first rendered.
But then i tried in codebehind lstArticles_ItemDataBound //Set default button right Panel tmpPanel = (Panel)e.Item.FindControl("pnlInput"); Button tmpButton = (Button)e.Item.FindControl("btnCart"); tmpPanel.DefaultButton = tmpButton.ClientID;
But when i tried that i get the execption when the page is rendered that the default button for a panel needs to be of type ibuttoncontrol. I also tried UniqueID, but the same happens.
Setting value in html control in code behind without making server control
<input type="text" name="txt" /> <%--Pleas note I don't want put runat=server here to get the control in code behind--%> <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
Code behind
protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { //If I want to initlize some value in input, how can I set here } } protected void Button1_Click(object sender, EventArgs e) { Request["txt"] // Here I am getting the value of input }
