Open RadWindow from within RadGrid template column - image button

[Gavin]

On my aspx page I have a RadGrid with the following:

<telerik:GridTemplateColumn HeaderText="View Order Details" UniqueName="OrderDetails">
<ItemTemplate>
<div style="vertical-align: middle; text-align: center;">
<asp:ImageButton ID="btnOrder" ImageUrl="~\Content\Images\list.png" runat="server" Height="25px" Width="25px"  OnClick="openOrderDetails_Click"/>
</div>
</ItemTemplate>
</telerik:GridTemplateColumn>

 

I have also tried replacing the onclick method with the below and calling the relevant switch statement (after putting in the OnItemCommand in the grid) :

CommandName="OrderDetails" CommandArgument='<%# Bind("identity") %>'

 

I have a test button outside my radgrid and when I click on this the window opens without any issues:

<telerik:RadButton ID="test" runat="server" Text="Test" Skin="MetroTouch" OnClick="openOrderDetails_Click"></telerik:RadButton>

 

Can anyone help with getting this to open from the button within the grid

Hello Gavin,

I advise you start from the following articles on opening a RadWindow:

• the recommended approach is to use JavaScript: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/getting-started/opening-windows.
• to open it from the server code, I advise that you use JS again, as shown here: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/opening-from-the-server.

Thus, you can attach client-side handlers to the button that will do the job, much like shown in this demo: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window (the handler is set from the code-behind but that is not really relevant).

As for the original problem - it is most likely due to AJAX being used and the RadWindow not being updated, especially if you try to show it via its VisibleOnPageLoad property.

Hi Marin,

Attaching the client-side handlers to the button has done the trick! Thanks for the help with this
