Opening a RadWindow from a button in header

[Donald]

Hi all,

I have a button in a GridTemplateColumn Header which I am using to open a RadWindow through code behind. Here is the .aspx:

<telerik:GridTemplateColumn UniqueName="CVATemplateColumn" InitializeTemplatesFirst="false">
  <HeaderTemplate>
     <asp:Button ID="id" runat="server" OnClick="NewWindowCommand" />
  </HeaderTemplate>
</telerik:GridTemplateColumn>

and in the code behind:

protected void NewWindowCommand(object sender, EventArgs e)
{
  RadWindowManager windowManager = new RadWindowManager();
  RadWindow radWindow = new RadWindow();
  // Set the window properties
  radWindowNavigateUrl = "radWindow.aspx";
  radWindow.ID = "radWindowId";
  radWindow.VisibleOnPageLoad = true;
  windowManager.Windows.Add(radWindow );
  Form.Controls.Add(radWindow );
}

In debug, the NewWindowCommand event handler fires and I can step through all the code, but no window appears.

However, using exactly the same event handler, if I have an asp:button outside the grid, if I click that everything works fine and the window appears.

<telerik:RadGrid>
....
</telerik:RadGrid>
<asp:Button ID="id" runat="server" OnClick="NewWindowCommand" />

Why this unexpected behaviour?
Any help would be appreciated,
Donald

Hello,

I have tried to reproduce the issue but no avail. Here is the code that I have tried.

ASPX:

<telerik:GridTemplateColumn>
  <HeaderTemplate>
      <asp:Button ID="Button1" runat="server" Text="open" OnClick="Button1_Click" />
  </HeaderTemplate>
</telerik:GridTemplateColumn>

C#:

protected void Button1_Click(object sender, EventArgs e)
   {
       RadWindowManager RadWindowManager1 = new RadWindowManager();
       RadWindow radWindow1 = new RadWindow();
       radWindow1.ID = "radWinowId";
       radWindow1.VisibleOnPageLoad = true;
       RadWindowManager1.Windows.Add(radWindow1);
       Form.Controls.Add(radWindow1);
   }

Thanks,
Princy.
