Stop RadWindow from always loading on page postback

[A W]

I am invoking a RadWindow as a dialog in my web page.

I am invoking from code-behind, since I need to pass some parameters:

radWindow1.NavigateUrl = url  + "?England,Germany,France";

radWindow1.VisibleOnPageLoad = true;

This works great, however it keeps reloading on each and every postback.

How can I stop the RadWindow from reloading? I don't mind code-behind or JavaScript to achieve this.

Hello,

There are several ways to resolve the problem.

• Set EnableViewState = "false" for the RadWindowManager
• Reset the VisibleOnPageLoad property to false with code when suitable, depending on the particular scenario
• Show the RadWindow through registering a script from the server instead of using server code.

Also checkout the following forun links which discusses similar scenario.

Thanks! Turning off the ViewState worked very well for me.

Set EnableViewState = "false" for the RadWindowManager worked for me when put the RadWindows inside the RadWindowManager.

Hi Princy,

I have tried all solutions. But my radwindow still reloads on each postbacks.
ASP:
 <telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
    <telerik:RadWindowManager runat="server" EnableViewState = "false">
    <Windows>
   <telerik:RadWindow ID="RadWindow1" Width="500px" Height = "600px" runat="server"  NavigateUrl="~/Customized/CustomizedControls/Member Directory/M_Adv_search.aspx"
   Title="Dialog"  VisibleOnPageLoad = "false">
</telerik:RadWindow> 
    </Windows>
    </telerik:RadWindowManager>  


 code behind:

  Dim script As String = "function f(){$find(""" + RadWindow1.ClientID & """).show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);"
        ScriptManager.RegisterStartupScript(Me, Me.[GetType](), "key", script, True)  

Appreciate you help..
Thanks,

Hi Mansi,

Try setting DestroyOnClose="true" for the window. If this doesn't solve the issue, provide your full code snippet.

ASPX:

<telerik:RadWindow ID="RadWindow1"  runat="server" VisibleOnPageLoad="false" DestroyOnClose="true">
</telerik:RadWindow>

Thanks,

Hey Princy,

Thanks for getting back.

That didnt work.. 

Is that because I'm using Radwindow in ASCX file ? 

Thanks again..

Hi Mansi,

Please try the following code snippet which works fine at my end.

ASPX:

<telerik:RadPanelBar runat="server" ID="RadPanelbar1" Skin="Outlook" ExpandMode="FullExpandedItem"

Thanks Princy,

I tried that and turned AutoPostBack="False" for all controls in Radpanelbar.

It works fine.
Thank you so much,

Mansi
