When using these addon's to your browser of choice, how can you peer into a control e.g. RADCOMBOBOX and see all of it's methods like get_text in the DOM??? I am having a hard time locating this method in the DOM while inspecting using Firebug or IE Dev toolbar.

How to allow end user to show or hide colums

I am a newbie to the Telerik controls. I have a Grid and I have successfully implemented a filter but what I want to do is to let the user decided which columns to show or hide.
My first reaction was, since I already have an "Apply filter" button in a RadToolBar, was to add a RadToolBarDropDown next to it. This means having to populate the Buttons in the DropDown dynamically. But there appears to be now way to FIND the RadToolBar control. Referencing its name doesn't appear to work. I;e., the ID is RadToolBar1 but when I type this in the .cs file it's not found by the intellisense.

So I thought I must be barking up the wrong tree so I tried alternative approaches but I can't find a solution. But I find it hard to believe I am the first person to try and let the user dynamically show and hide columns. So I suspect there is a far simpler method that I am missing.

Any help pointing me in the right direction would be much appreciated.

I've noticed in your internal builds that you fixed an error caused by RadBinaryImage when ResizeMode="Fit". I was wondering if this is the same error, but is being caused by ResizeMode="Crop".

If you could tell me if this is a RadBinaryImage error or is it being caused by something else like my server.

Thanks.

Microsoft JScript runtime error: 'get_postBackElement().id' is null or not an object

Hello every body!

I have a very strange problem with Radajaxmanager and updatepanel ,Please see this senario:

I have an aspx file that inherited from a masterpage,in this page I am using some javascript code with

fcbkCompelet jquery plugin(see[ http://www.emposha.com/demo/fcbkcomplete/]).I want to update

information about user entry information in SELECT INPUT tag that work

with this plugin(something like yahoo autocompelet addressbar ).In the other side in the same page I have a <ASP:Label>

that will be updated with some information fetched from Database when user typed username for

example.I am using a Radajaxmanager ,updatepanel,asp:timer with some codebehind to fetch this

information to update the asp:label in every 2 seconds without any postback , but In IE 8 I get this error

”Microsoft JScript runtime error: 'get_postBackElement().id' is null or not an object”

, but no error in Fireox and chrome and it dose not work in all three cases.The point Is that

It do work when I copy the whole aspx file content with the inherited masterpage with the same

Structure , the same js files and jquery plugin to a new test Project .I am confused that

Why it works in new test project but it get error in my main project.I am sure that it is the same code

and structure in the both projects.I should demonstrat that both projects are in Telerik Q1 2011

template form.
