I have RadGrid inside of RadWindows. I need to refresh RadGrid every time when RadWindow shows. How to do it?

<script type="text/javascript">

function closeCustomConfirm() {

$find("<%=rwApproveInstance.ClientID %>").close();

}

function ShowRadWindow() {

var oWnd = $find("<%=rwApproveInstance.ClientID %>");

oWnd.show();

}

</script>

<telerik:RadWindowManager runat="server" ID="RadWindowManager1" >

<Windows>

<telerik:RadWindow ID="rwApproveInstance" Modal="true" Behaviors="Close, Move" VisibleStatusbar="false"

Width="800px" Height="700px" runat="server" ReloadOnShow="True" ShowContentDuringLoad="False">

<ContentTemplate>

<div class="rwDialogPopup radconfirm">

Hi,

With respect to this forum thread there is no "reload" method for content template containers (in the framework) and the main reason for that is that there is no way to know what exactly the user /developer wants - should the content be reset, or should it preserve some values.

One suggestion is that you can refresh the ContentTemplate manually and you need to put the update panel directly in the ContentTemplate as shown below.

ASPX:

<telerik:RadWindow ID="rwApproveInstance" .........>

<ContentTemplate>

<asp:UpdatePanel ID="Updatepanel1" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<telerik:RadGrid ID="RadGrid1">

..............

</telerik:RadGrid>

</ContentTemplate>

</asp:UpdatePanel>

</ContentTemplate>

</telerik:RadWindow>

JS:

<script type="text/javascript">

function OnClientShow(sender, args) {

var grid = $find("<%= RadGrid1.ClientID %>")

grid.get_masterTableView().rebind();

}

</script>

Hope this helps.

Regards,
Princy.

I could resolve the issue. You have to open RadWindows from code behind and refresh data manually.

string script1 = "function f(){$find(\"" + rwActivityGrid.ClientID + "\").show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";

RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "ShowRadWindowInstance", script1, true);

rgActivityGrid.DataSource = GetDataSource();

rgActivityGrid.DataBind();
