Setting Id To A Panel Control In Gridview?
Mar 15, 2010
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!!!
}
}
}

<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'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.

I have a gridview that displays entries from a data table. I am giving users the ability to select a subset of the data in the table by having a textbox and search button in the grid view header. The search button fires the gridview row command, and changes the underlying sqlDataSource's select command, and adds the text value from the text box as a parameter.
Also, I have a "Show All" button in the header, that clears out the select parameters, so all entries in the table are shown. Again, this works perfectly.
What is NOT working is controlling the visibility of the "Show All" button control. Below is the html markup for the data grid header template:
<HeaderTemplate>
<asp:Button ID="btnShowAll" runat="server" CausesValidation="False" CommandName="ShowAll" Text="Show All" />
<asp:Button ID="btnSearch" runat="server" CausesValidation="True" CommandName="Search" Text="Search" ValidationGroup="vldSearch" /><br />
<asp:TextBox ID="txtSearchName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="vldSearchName" runat="server" ErrorMessage="You have to provide an attorney name to search for." Text="*" ControlToValidate="txtSearchName" ValidationGroup="vldSearch" ForeColor="White"></asp:RequiredFieldValidator>
</HeaderTemplate>
In the Row Command event handler, here is how I am setting the visibility of the button:
If Not Me.dgAttorneys.HeaderRow Is Nothing Then
Dim btnShowAll As Button = Me.dgAttorneys.HeaderRow.FindControl("btnShowAll")
btnShowAll.Visible = Me.sqlAttorneys.SelectParameters.Count > 0
Trace.Write("Show all status is " & btnShowAll.Visible.ToString)
End If
The trace statement is showing the correct visible status - if the "show all" button is clicked, I do a SelectParameters.Clear() on the sqlAttorneys sqlDataSource.
Is my problem due to a misunderstanding of how the "FindControl" method works - I had assumed my new btnShowAll that I define is actually a reference to the "physical" control on the aspx page, so any changes I make to my local object is reflected in the control on the page.
If this is not the case, what is the best way to get a reference to the button control in the header row of the grid view?

I am in need of some assistance in regards to how to best set the values of properties for a Web User Control which is being included into a cell of a GridView with dynamically created columns. I have tried a few different approaches, but can't seem to get a satisfactory result. Also, to be completely honest, I am not really sure if I am using best practices for what I am trying to accomplish.
First off a little background:I have a GridView for which we will never know the exact number of columns at run time. The columns are predicated by user selection. I am creating the command text for the DataSet on the fly and then looping through the columns of the resulting DataTable in order to use custom TemplateFields. This works ok for just printing out the row values but not so much for when I need to insert the Web User Control into a cell.The Web User Control is in essence a collection of image links which are used as a "Quick Nav" tool. I need to pass the values of 2 fields from each DataRow to the control via properties (for example, CustID and ProductID). I am using custom TemplateField classes inheriting from ITemplate for displaying my fields and extending the DataBinding event like so: [Code]....
This won't work for my User Control as DataBinding is called after the control is loaded into the page and I need the properties to be set before the Page_Load event of the control is fired.Is there a GridView event I should be looking into instead such as RowCreated or RowDataBound? Or should I modify how I loop through the DataTable by doing rows first, then the resulting columns as I've seen done elsewhere?

I use a modalpopupextender to show a popup when the user clicks on a button.
<ajaxToolkit:ModalPopupExtender ID="mpe1" runat="server" TargetControlID="statusInfoLb" PopupControlID="statusInfoPanel" DropShadow="false"
OkControlID="okBtn" OnOkScript="onOk()">
</ajaxToolkit:ModalPopupExtender>
<asp:Panel ID="statusInfoPanel" runat="server" Height="185px" Width="454px" SkinID="Panel_Notification2" DefaultButton="okBtn">
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 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 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:
<input onKeyPress="javascript:if (event.keyCode == 13) {$(this).change(); $('#submitclientid').click();}" ...>
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 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 put a GridView control in a Panel control so that the GridView's rows can be scrolled vertically. With selection of row enabled for a Button field, I am able to select any row with the selected row background color highlighted. Problem is when you scroll down to a row that is way pass the Panel height and select the row, after postback the GridView will render to show the top rows which are visible within the Panel height. So the selected row in it's background color cannot be seen.

I have a panel that contains several controls.
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 3 level deep nested gridview. The expansion/contraction of each record was originally done with javascript. There were html <div> tags around each gridview. Since these were HTML div tags I could give them IDs that were dynamically bound to record ID value within the database. I then had onclick buttons that passed in a bound record ID value that coresponded to the appropriate div tag that needed to be expanded (e.g. display: inline (show it) or if it is already inline then display: none).
This worked beautifuly. Unfortunatley I wanted to be able to do in-girdview editing of the child records. When expands a parent record and clicks to edit a child record the OnRowEdit event fires which automatically generates a postback and resets the variables within the JavaScript. THEREFORE THE ENTIRE GRIDVIEW STATE BECOMES CONTRACTED.
So finally I decided to change the div tags to <asp: Panel> and the onclick images to .net clickable images (all .net objects no framework). This works because the state is remembered within each postback. However, the problem I'm having is I can't dynamically bind ID's for panel since this is not allowed. HOW CAN I GIVE THE PANEL <% Bind("id") %>. THAT I CAN REFER TO SO I CAN OPEN THE APPROPRIATE PANEL.
