RadGrid deselect not always firing SelectedIndexChanged

Hello, I have the following RadGrid issue:

Multiple row selection is turned on.
Client side selection is turned on.
ASP.NET AJAX RadGrid version 2009.01.0402.35.

All of this is OK:
When I select a row and then postback, SelectedIndexChanged fires correctly.
When I select a 2nd row and then postback, SelectedIndexChanged fires correctly.
When I select a 3rd row and then postback, SelectedIndexChanged fires correctly.
When I deselect a row and then postback, there are two rows selected, and SelectedIndexChanged fires correctly.
When I deselect another row and then postback, there is one row selected, and SelectedIndexChanged fires correctly.

This is the problem: When I deselect the final selected row, so there are now no selected rows, and then post back, SelectedIndexChanged does NOT fire. It happens every time I deselect the final selected row, regardless of how much selecting/deselecting I do.

Here is my ASPX code:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="AddressTypes.aspx.cs" Inherits="foo.AddressTypes" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<html>

<head runat="server">

<title>Test Page</title>

</head>

<body>

<form runat="server">

<asp:ScriptManager ID="sm" runat="server" />

<asp:ObjectDataSource ID="gridDS" runat="server" TypeName="foo.AddressTypes" SelectMethod="GetRecords" />

<telerik:RadGrid ID="grid" runat="server" DataSourceID="gridDS" OnSelectedIndexChanged="Grid_SelectedIndexChanged"

AllowMultiRowSelection="true">

<ClientSettings>

<Selecting AllowRowSelect="true" />

</ClientSettings>

</telerik:RadGrid>

<asp:Button ID="button" runat="server" Text="Postback" />

</form>

</body>

</html>

Here is my code-behind:

using System;

using System.Collections.Generic;

using System.Web.UI;

namespace foo

{

public partial class AddressTypes : Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

public static Dictionary<string, string> GetRecords()

{

Dictionary<string, string> dict = new Dictionary<string, string>();

dict.Add("Test 1", "Test record number 1");

dict.Add("Test 2", "Test record number 2");

dict.Add("Test 3", "Test record number 3");

dict.Add("Test 4", "Test record number 4");

dict.Add("Test 5", "Test record number 5");

return dict;

}

protected void Grid_SelectedIndexChanged(object sender, EventArgs e)

{

Response.Write("SELECTED INDEXES: " + grid.SelectedIndexes.Count);

}

Everything works fine until that last selected row is deselected. All of the row deselection is done using CTRL-Click, and adding a selection column to the grid is not an option. Can you help me determine why SelectedIndexChanged does not fire when the last selected row is deselected? Thank you.

set the export file name and extension of excel

I have followed a lot of the things online but my export filename seems to work but not the extension of the excel file. It always ends up being aspx and it gives me the trusted file error. I think I am getting this because it does not like the aspx extension.

Disable Image Properties

Is there a way to disable the Image Properties (right click on image) within the Editor? In our app, images are resized and formatted on upload so there's no need for users to use it.

Problem Using RadAjaxManger with nested controls

Hello Experts,

I'm new with Telerik and I have a problem which i'll describe bellow:

[PREFACE]

Imagine this structure:

Default.aspx
|
|
|======> Modules|
|
|----> Module1|--->UserControl1.ascx
|--->UserControl2.ascx

there is some modules in this structure. i have a master page with a runat=server tagged DIV tag. whenever i want to use the appropriate module, I would just use the LoadControl() method and assign the loaded user control to the spoken DIV. for example if I want to use module "Module1":

contentPlaceHolder.Controls.Add(LoadControl("Modules/Module1/UserControl1.ascx"));

each user control has the appropriate controls and layer to handle requests.

[MY PROBLEM]

all the first level loadings will take place via real postback. in the first level loaded user control i have a <Telerik:RadAjaxManager> tag with the specified controls added to it and it works fine (thanx to telerik developers). the problem comes when I try to load another user control in an ajaxified DIV (for example).

When I load the specified control, I want to register new ajax settings for that dynamic loaded user control's controls collection.
BUT I CANT

any idea???

exporting radgrid fails

Hello,
I have a solution contains radgrid in witch there are also template columns.
Calling the ExportToExcel method from a button event of export falls with the error:
"Object refernce" in pre-render of grid event, because of hiding the checkbox column.
And even if i skip the per-render code by flag, the export doesnt work.
Actually the export doesnt work and my grid on screen has no checkbox anymore but "false" in the column.
I have tried hiding the column, but nothing helps.
I have spent many hours reading same problems but none of the solutions helped me.
I also tried putting standard code of exporting, like gridview (with response and htmltextwriter) but it falls with error:

יש למקם את הפקד '

ctl00_contentBody_gridInviteds_ctl00_ctl02_ctl00_ctl00' מסוג 'GridLinkButton' בתוך תג טופס עם runat=server.

Actually, when my grid is with no template columns, the export is working but still there is a poblem that the headers have a button in the excel sheet, even though i wrote in code "allowSorting=false"

thanks,
gila
