Need help with adding a header to a new radWindow

[JenMaryland]

I'm creating a user control that adds a new window to the RadWindowManager. I'm trying to add a header to the window, which seems easy enough in the demo code, but I'm getting an error that says "'header' is not a member of 'Telerik.Web.UI.RadWindow'.". I'm new to jquery and Ajax controls, so I don't know if I'm missing something.

(Telerik version is 2014.3.1024.45)

ascx file -

<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
<telerik:RadWindowManager RenderMode="Auto" ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false" ReloadOnShow="True" runat="server" EnableShadow="true" EnableViewState="False">
  <Shortcuts>
    <telerik:WindowShortcut CommandName="RestoreAll" Shortcut="Alt+F3"></telerik:WindowShortcut>
    <telerik:WindowShortcut CommandName="Tile" Shortcut="Alt+F6"></telerik:WindowShortcut>
    <telerik:WindowShortcut CommandName="CloseAll" Shortcut="Esc"></telerik:WindowShortcut>
  </Shortcuts>
</telerik:RadWindowManager>

Code Behind -

Public Sub ShowModalDialog(ID As String, URL As String)

  Dim newWindow As New RadWindow()
  'NavigateUrl to be chosen dynamically.
  newWindow.ID = ID
  newWindow.NavigateUrl = URL
  newWindow.VisibleOnPageLoad = True
  newWindow.OnClientClose = "OnClientClose"
  newWindow.Modal = True

  newWindow.header = "Test"


  newWindow.Shortcuts.Add(NewWindowShortcut("Maximize", "Ctrl+F2"))
  newWindow.Shortcuts.Add(NewWindowShortcut("Restore", "Ctrl+F3"))
  newWindow.Shortcuts.Add(NewWindowShortcut("Minimize", "Ctrl+F8"))

  RegisterControl(ID)
  ModalWindow.Windows.Add(newWindow)

End Sub

Hello Jennifer,

RadWindow for ASP.NET AJAX does not have a Header property, just like the compiler errors out. Could you point me to the AJAX demo you use as base because I am not aware of such a resource that we provide? To create a header you would need to create it in your own content (either in the ContentTemplate, or in the content page), and optionally hide the built-in titlebar by setting the VisibleTitlebar property to false.

On a side note, to open a RadWindow from the server, I advise you register a script as shown in the documentation: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/opening-from-the-server. There are multiple ways to open a dialog and I also advise you review the following article to see them all and choose the one that will fit your needs best: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/getting-started/opening-windows.

I was looking at this page - http://docs.telerik.com/devtools/wpf/controls/radwindow/features/window-header

VB.NET
Dim radWindow As New RadWindow()
radWindow.Header = "My RadWindow"

That's what I was trying to do.

Hi Jennifer,

The article you linked is for the UI for WPF suite and is not applicable for the UI for ASP.NET AJAX suite.

With RadWindow for ASP.NET AJAX you need to define the desired layout in the content you provide, there is no Header property or header template.

RadDock offers a header template, however, so you may want to see whether it fits your requirements: http://demos.telerik.com/aspnet-ajax/dock/examples/edittitle/defaultcs.aspx. Note that it is not designed for arbitrary content and the more content you put there, the more likely it is that the control will appear broken.
