change window height from code behind

[Clive Hoggar]

Hi

I have put a radajaxpanel in the window content that opens when
a check box is checked to display more items in a form.  

This adds height to the page and creates the need for scroll bars
(which appear) but I would prefer to automatically extend the height
of the window to accomodate the additional form items.
How can I do this from the code behind in the same sub that makes the
panel visible? (VB)

I am sure it is easy .. but I just can't figure it out.

I have tried this - but it does nothing - maybe because the window is not updated
at that point?

Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
        If CheckBox1.Checked Then
            RadAjaxPanel1.Visible = True
            Dim RadWindow1 As New RadWindow
            RadWindow1.Height = Unit.Pixel(450)
        Else
            RadAjaxPanel1.Visible = False
        End If
    End Sub

thanks

Hello Clive Hoggar,

I am not sure that where you placed the RadAjaxPanel, whether in RadWindow or in the parent page. I tried the code snippet below in order to show the RadWindow according to desired height.

VB:

Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As EventArgs)
    If CheckBox1.Checked Then
        '   RadAjaxPanel1.Visible = true;
        Dim newWindow As New Telerik.Web.UI.RadWindow()
        newWindow.NavigateUrl = "Window1.aspx"
        newWindow.Height = Unit.Pixel(450)
        newWindow.VisibleOnPageLoad = True
        form1.Controls.Add(newWindow)

    Else
        '    RadAjaxPanel1.Visible = false;
    End If
End Sub

Thanks,
Princy.

Hi Clive Hoggar,

Once the RadWindow is created on the client you can change its dimensions by using the client-side API (setSize()). If you want to do that from the server, you will need to close and recreate the RadWindow every time.
