RadWindow not working in IE8

[John Prajwal]

Hi ,

I have a radwindow which opens as model pop up. Its working fine IE6.
I am migrating my application to IE8. In IE8 it opens a pop up window but immediately it closes.

Below is code:

Javascript function:

 function OpenAddWindow()
         {
             window.radopen('activitydetail.aspx', 'AddActivity')
         }
Wep page

 

<

 

radW:RadWindowManager ID="RadWindowManager1" runat="server">

 

 

 

 

 

<Windows>

 

 

 

 

 

<radW:RadWindow

 

 

 

 

 

Modal="true"

 

 

 

 

 

ReloadOnShow="true"

 

 

 

 

 

ID="AddActivity"

 

 

runat="server" Width="450" Height="350"

 

 

 

 

 

NavigateUrl="activitydetail.aspx"

 

 

 

 

 

OnClientClose="ClientCallWindow" />

 

 

</Windows>

 

 

 

 

 

</radW:RadWindowManager>

 

 

 

 

<

 

button  id="btnAddAct" onclick="OpenAddWindow()">Add Activity</button>

Hello John,

The reason for this behavior is that you are not canceling the postback. Basically what happens is:

1. You click the button.
2. The JavaScript code fires and opens the RadWindow
3. Postback occurs which reloads the page.

To avoid that, you should cancel the postback - for example you could use
<button  id="btnAddAct" onclick="OpenAddWindow(); return false;">Add Activity</button>

HI Georgi,

has this got anything to do with IE setting?

as there is only one of my user having this problem.

Hi Samantha ,

This logic is not browser's setting dependent - if you return false after the name of a JavaScript function in in the OnClientClick (onclick in HTML), there should be no postback.

Dear Team,

 Still same issue, the page get refreshed and popup closed. This is happening only in IE8.

Hi Atif,

You should use the RadButton client-side API:

<telerik:RadButton runat="server" Text="RadButton" ID="btnAdd" OnClientClicking="fnAddUser"></telerik:RadButton>

<script language="javascript" type="text/javascript">
    function fnAddUser(sender, args) {
        window.radopen("AddUser.aspx", "trwAUWin");
        args.set_cancel(true);
    }

    function OnClientclose(sender, eventArgs) {
    }


</script>
