Ajax Error on XP

We have multiple telerik controls on a page and any time you click on the in IE 8 on a win xp machine we get the error attached. Do you know of any solution for this? I should note that the commands (such as a delete command in a gridview, an upload command, etc) actually work, it just pops up with that ajax error every time. Any ideas?

RadMenu in Site.Master slides under text boxes in child pages

I currently have an issue where a RadMenu in a Site.Master page seems to slide under a txtbox when expanded (see attachement).

This seems to only impact IE. Any thoughts?

Getting at the GridCommandItem via the client-side API

Normally, if I need a client-side reference to the grid's CommandItem, I wire up the Toolbar's OnClientLoad command and save the reference when that fires. Either that or use $find(...).

However, I find myself updating a page that used multiple instances of a user control that has a grid in it and i need to access the CommandItem for a grid when a row on the grid is selected, but for the life of me I can't find anything in the API that allows me to get at the CommandItem from, say, the OnRowSelecting event.

Is this possible?

The problem is it works great if at least one record exists but if I have a collection of object with count = 0 (no records) and I click the add new record button i get a:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: DataBinding: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'ThresholdName'.

What am I doing wrong?

How to remove the columns in the viewstate.

Hi,

I am binding the radgrid using normal datasource and databind method.

the grid is getting filled with autogenerated columns. I have placed one checkbox which is in the grid, not auto generated.

Now, on post back usong any button in the page. the data in the viewstate also gets loaded. this creates addtional column. I did
radgrid.MasterTableView.Columns.Clear();

the reaction is, this will also remove the checkbox in the item template. I am not sure on how to add check box and header text box in the item template in radgrid programmatically. the example given in telerik site is not helpful.

http://www.telerik.com/help/aspnet-ajax/grid-programmatic-creation.html

I requrie a solution, on how to added a column which checkbox programmatically or

running this without touching template column or
prevent viewstate from acting on button postbacks.

thanks in advance.
