Panel DefaultButton NOT IButtonControl?
May 18, 2010
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?

UserAddToList.ascx
<asp:Panel ID="Panel1" runat="server" >
<sikt:PartFormTextboxLine runat="server" ID="samAccountName" />
sikt:PartFormTextBoxLine runat="server" ID="name" />
<sikt:PartFormButtonLine runat="server" ID="addButton" UseSubmitBehavior="true" />
</asp:Panel>
PartFormButtonLine ascx:
<div>
<asp:Button ID="Button" runat="server" onclick="Button_Click" />
</div>
I wish to set the default button of the panel to the button in PartFormButtonLine.
This is tested:
Findcontrol
Button bt = (Button)addButton.FindControl("Button");
Panel1.DefaultButton = bt.ClientID;
(also tested Panel1.DefaultButton = bt.ID; Panel1.DefaultButton = bt.UniqueID;)
Making a field: Panel1.DefaultButton = addButton.Button.ID;
(also tested Panel1.DefaultButton = addButton.Button.ClientID; Panel1.DefaultButton = addButton.Button.UniqueID;)
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 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) { }
[code]...

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 %>" />

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.
My search panel in my master page
<asp:Panel runat="server" ID="pnlSearch" DefaultButton="btnSearch">
<asp:TextBox ID="txtSearch" CssClass="fld" runat="server" Width="160" Text="Search..."
onclick="this.value='';" CausesValidation="false"></asp:TextBox>
<asp:ImageButton ID="btnSearch" ImageUrl="~/Images/search_arrow.gif" runat="server"

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:
UserAddToList.ascx
<asp:Panel ID="Panel1" runat="server" >
<sikt:PartFormTextboxLine runat="server" ID="samAccountName" />
<sikt:PartFormTextBoxLine runat="server" ID="name" />
<sikt:PartFormButtonLine runat="server" ID="addButton" UseSubmitBehavior="true" />
</asp:Panel>
PartFormButtonLine ascx:
<div>
<asp:Button ID="Button" runat="server" onclick="Button_Click" />
</div>
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
"onkeypress="javascript:return WebForm_FireDefaultButton(event, 'MainContent_UserAddToList_addButton')"
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}

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.
Code is as below:
<asp:Panel ID="pnlSearchBox" runat="server" class="search-main-box" DefaultButton="lnkSearch">
<asp:TextBox ID="txtLocation" runat="server" CssClass="input-field" MaxLength="200" style="width: 182px; margin-bottom: 7px;"></asp:TextBox>
<ajaxToolkit:AutoCompleteExtender runat="server" BehaviorID="AutoCompleteEx" ID="aceLocation"

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:
idTextBoxFA.Attributes.Add("onkeydown","if(event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementBtId('" + noEnterButton.UniqueID + "').click();return false;}} else {return true}; ");
All my page controls are in a form and I tried giving the form "defaultButton" property to that button I created. That didnt work either.

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.:
btnPick12.Attributes.Add("onClick", "return Pick12();")
And in the page Head I have the script
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.)
The aspx:
<asp:Panel id="thePanel" runat="server">
<asp:Button ID="btnAddTag" Text="Add Tag" runat="server" />
</asp:Panel>
The vb:
tagPanel.DefaultButton = btnAddTag.UniqueID
The exception:
The DefaultButton of 'tagPanel' must be the ID of a control of type IButtonControl.
The value of btnAddTag.UniqueID is ctl00$phMain$btnAddTag (there's a master page, this section is called phMain).
I've also tried CType(tagPanel.FindControl("btnAddTag"), Button).UniqueID.

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.

In addition to having the add to cart button "clicked" to add the product, I would also like the user to be able to hit enter when they are finished entering the qty in the textbox for the item. Is there a way to allow the DefaultButton to change to the add to cart button of the row i'm on?

I am having trouble wiht my AJAX collapsible Panel Extender. I have the CPE opening a panel that contains the Table of Contents of a document being displayed on the page. A user clicks on the link for a certain part of the document, the event triggers a C# function that gets the file that particular section is contained in an displays the section. Right now you have to, of course, click on the TitlePanel to open and to close the CPE. What I want to do is have it close automatically whenever a link inside the content panel has been clicked. I have tried placing this.cpeTOC.Collapsed=true; in the functiion that gets the files but it does not work. I have also tried the autocollapse property of the CPE and it just collapses whenever someone moves thier mouse from the titlepanel.

I have a panel and a background image. to stretch this image in the panel if the height is adjusting. I have tried to google this but have trouble find a solution for this.The image has the size: (647 X 158).
The only thing that will change is the height of the panel. Now it does repeat by default. no - repeat will probably only make the image its orignal size wich is not stretching it out over the whole panel.Otherwise I am thinking of change the size of the image itself in C#. [Code]....

I am using Ajax Control ToolKit's Accordian Control with 5 Accordian Panel. Contents of Accordian Panel are UserControl. Currently I have added all in the design mode, But it making my page slow because it loads all the content at a time. So, I want this to be dynamic. When User Click on Header of Accordian Panel, It loads the user control dynamically and also asynchronously.
I tried to put the user control under UpdatePanel which I placed under Accordian Content Panel but this is not working. Also I want to display loading images if getting slow response from server. how can I achieve it. It will be better if you provide an example.

Using VB, VS2010, I have a large image in a panel and want to be able to pop-up panels while hovering over it. This one large image is a picture of a lot of components that I woulld like to treat individually when I hover them. I have done this before by placing a transparent button in another panel that is absoultely positioned over the larger one. I have the button transparent with a border that shows up using hover in css. Everything works fine expcept that the panel does not show itself in the right place when viewiing in the browser window. It shows fine in design view, but shifts over while browsing in the browser. I have tried making all panels absolutely positioned. Still a problem. Is there a better way to put a panel over a panel?

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
