I am trying to update a RadLabel control that is inside of a RadlistView which is inside of a RadAjaxPanel. I have a user control on my aspx page that calls a public event handler when a modal on the user control closes. I can access the RadLabel, but it doesn't update.
Here is my HTML:
<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1" BackColor="White">
<div class="form-group">
<asp:RadioButtonList ID="radioChoice" runat="server" RepeatDirection="Horizontal" AutoPostBack="true" CssClass="inline-rb" OnSelectedIndexChanged="radioChoice_SelectedIndexChanged">
<asp:ListItem Value="Multiple" Text="Multiple Record Report" Selected="True" />
<asp:ListItem Value="Single" Text="Single Record Report" />
</asp:RadioButtonList>
</div>
<asp:HiddenField runat="server" ID="panelCollapse" ClientIDMode="Static" />
<asp:HiddenField runat="server" ID="SelectedItem" />
<hr />
<telerik:RadListView runat="server" ID="radlistview1" OnItemDataBound="radlistview1_ItemDataBound" EnableViewState="false">
<ItemTemplate>
<div class="panel panel-default">

Here is my EventHandler:
private void JobFilterControl_CustomJobFilterSaved(object sender, EventArgs e)
{
foreach (RadListViewItem item in radlistview1.Items)
{
string module = ((HiddenField)item.FindControl("hfModule")).Value;
RadLabel filterName = item.FindControl("filterName") as RadLabel;
switch (module)
{
case "JOB":
filterName.Text = "Selected Filter: " + Session["SavedJobFilterName"].ToString();
break;
case "TICKET":
filterName.Text = "Selected Filter: All";
break;
}
}
}
All of the code works as expected except that the Label Text does not update. Is there anyting I can do to get this to work? Any assistance is greatly appreciated.
