Post back not firing unless default.aspx in URL

I have a very simple project set up. I created it in VS2010...create Telerik Web Application. I didn't change any of the options in the Telerik wizard. The site has a default page on the root and one subfolder also with a default page.

When I navigate to http://hostname everything works fine. The default page on the root works as expected. When I navigate to http://hostname/subfolder, the default page loads but I can't get the post back to fire. If I navigate to http://hostname/subfolder/default.aspx it works.

This behavior does not occur on non-Telerik pages.

This behavior does not occur on the .net dev server; it occurs on IIS.

The default page is set correctly in IIS and I believe the page directive is correct.

Here is the aspx markup:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="default.aspx.vb" Inherits="TelerikWebForm" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" />

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

<Scripts>

<%--Needed for JavaScript IntelliSense in VS2010--%>

<%--For VS2008 replace RadScriptManager with ScriptManager--%>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />

</Scripts>

</telerik:RadScriptManager>

<script type="text/javascript">

//Put your JavaScript code here.

</script>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

</telerik:RadAjaxManager>

<div>

<asp:Button ID="Button1" runat="server" Text="Button" /><asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

</div>

</form>

</body>

</html>

Here is the code behind:

Imports Telerik.Web.UI

Partial Class TelerikWebForm

Inherits System.Web.UI.Page

Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click

Label1.Text = IsPostBack & " : " & Now

End Sub

End Class

Any ideas?

Formatted Label in GridTemplateColumn

Greetings,

I am using the following GridTemplateColumn in a RadGrid...

<telerik:GridTemplateColumn HeaderText="Phone" ItemStyle-Wrap="False">

<ItemTemplate>

<asp:Label ID="lblNotifyingIndividualPhoneNumber"

runat="server"

Text='<%# string.Format("{0:(###) ###-####}", Convert.ToInt64(Eval("NotifyingIndividualPhone")))%>'>

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

The problem is when the database field "NotifyingIndividualPhone" is null or empty, it throws an error: "Input string was not in a correct format". Any ideas how to get around this issue?

Your help is appreciated!
Matt

Rad Tool Tip Manager And Each Rad Treenode

Hi, to simplify my requirement, I would say, I want to display the text of the RadTreeNode in the RadToolTipManager's tool tip

Below is how my code looks currently:

<telerik:RadTreeView ID="MainTree" runat="server" Skin="WebBlue" BackColor="white" EnableDragAndDrop="false" EnableDragAndDropBetweenNodes="false" Height="100%" OnLoad="LoadMainTree" Visible="true" OnContextMenuItemClick="ContextMenuItemClick">

</telerik:RadTreeView>

<telerik:RadToolTipManager ID="RadToolTipManager1" runat="server" OnAjaxUpdate="RadToolTipManager_AjaxUpdate" Skin="Sunset">

</telerik:RadToolTipManager>

RadToolTipManager_AjaxUpdate has following implementation in the code behind:

internal static void RadToolTipManager_AjaxUpdate(object sender, ToolTipUpdateEventArgs e)

{

System.Web.UI.WebControls.Label lblTitle = new System.Web.UI.WebControls.Label();

lblTitle.Text = "Title";

lblTitle.Attributes.Add("style", "font-weight: 700");

System.Web.UI.WebControls.Label lblCaption = new System.Web.UI.WebControls.Label();

lblCaption.Text = "This is the the hard coded string but I want to print the text of the RadTreeNode, over which I hover my mouse...";

e.UpdatePanel.ContentTemplateContainer.Controls.Add(lblTitle);

e.UpdatePanel.ContentTemplateContainer.Controls.Add(lblCaption);

}

The LoadTree Event handler ...

private void LoadTree()

{

RadToolTipManager1.ShowDelay = 100;

RadToolTipManager1.HideDelay = 100;

RadToolTipManager1.AutoCloseDelay = 8000;

RadToolTipManager1.TargetControls.Add("MainTree");

}

Would you please do me a favor by posting codes for the server-side and/or client side, too ? So I can implement the most suitable of those.....

I do not want to go the .ascx way, as demonstrated on the Demo page.

Thanks,
-Aarsh
