[Solved] preventing window from showing each time page is reloaded

[Dave]

I realize that the reason my radwindow loads every time the page is reloaded is because I have the visibleonpageload property set to true, but I don't want this behavior to happen.  I have looked at a similar post located at http://www.telerik.com/community/forums/thread/b311D-mhctd.aspx, but I need a more concrete example of how you can prevent the window from popping up every single time the page is reloaded.  I want the window to load up only when the user clicks on the appropriate asp:linkbutton control.

Thanks,
Dave

Hello Dave,

The code that Tsvetie posted at the end of the other forum thread is exactly what you need. Basically, before you open a RadWindow you need to check for a flag in the session that "tells" you if such window is already opened and to set VisibleOnPageLoad to true only if this flag is not present.

I tried using Tsvetie's code, but that code didn't work because once you set that session variable, it will prevent the window from loading up even when the user didn't reload the page, but actually clicked on the appropriate linkbutton.  Am I missing something?  It doesn't seem like that code would work.  Here's what I did.  I put the following code in the click event of my linkbutton:

Protected Sub lnbProjRole_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lnbProjRole.Click

Dim reload As String = Session.Item("reload")

If String.IsNullOrEmpty(reload) Then



'Create a new window and add it dynamically



Dim newWindow As RadWindow = New RadWindow

newWindow.ID = "RadWindow1"



newWindow.NavigateUrl = "./Dialog.aspx"



newWindow.VisibleOnPageLoad = True



newWindow.Enabled = True



newWindow.Visible = True



newWindow.Width = 285

newWindow.Height = 650

newWindow.Behaviors = WindowBehaviors.Close

newWindow.Skin = "WebBlue"



newWindow.OffsetElementID = "searchArea"



newWindow.ReloadOnShow = True



newWindow.Modal = True



newWindow.OnClientClose = "initiateCallback"



newWindow.VisibleStatusbar = False



'Add the newly created RadWindow to the RadWindowManager's collection



Singleton.Windows.Add(newWindow)

End If



End Sub

 I also added the following line of code to the click event of the postback button that gets clicked after the radwindow is closed:

Session.Add(

"reload", "blahblahblah")

The problem is that this code only allows the radwindow to open once and only once per session.  I want the user to be able to open the radwindow as many times as they want by clicking on the linkbutton.  I only want the radwindow not to show if they just reloaded the page.

By the way, I just opened a support ticket regarding this.
