Radgrid onselectedindexchanged for 2 buttons

I have 2 buttons (GridButtonColumn) on the radgrid doing different action, the first one

<telerik:GridButtonColumn CommandName="Select" DataTextField="TagID" ButtonType="ImageButton"ImageUrl="images/go.gif" UniqueName="colgo" ></telerik:GridButtonColumn>

<telerik:GridButtonColumn CommandName="Select" DataTextField="TagID2" ButtonType="ImageButton"ImageUrl="images/go2.gif" UniqueName="colgo2" ></telerik:GridButtonColumn>

By using onselectedindexchanged

="rgSearch_SelectedIndexChanged", which allows me to put code behind under

protected void rgSearch_SelectedIndexChanged(object sender, EventArgs e)

{
}

How can I idendify under rgSearch_SelectedIndexChanged, the sender is from which button, in order to put different action code in.

Thanks,
Jessie

RadEditor MOSS 2007 removes style

Hello,

We have an issue with RadEditor MOSS 2007 removing a style attribute. The original HTML in a SharePoint Wiki item contains the following:

<TD class=detailsHeader background=/PublishingImages/sectiontitle_03.gif>

When that page is ediied with RadEditor activated, that code is tranformed to:

<td style="background-image: url(/publishingimages/sectiontitle_03.gif);" class="detailsHeader">

When the page is saved, the style attribute is removed.

Can you explain why this happens, or if there is a way to prevent this behavior?

Thank you,
Craig Smith

Response.Write error

Hi all,

in RadAjaxManager1_AjaxRequest event I select data from database into reader, then if reader is Nothing i want to prompt alert
Response.Write("<script>alert('There is no Data to show');</script>") .

when I run alert didn't prompt, just got as below

...

Error: Sys.WebForms.PageRequestmanagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the reponse is modified by calls to Reponse. Write(), reponse filters, httpModules, orserver trace is enabled.
Detail: Error parsing near '<script> alert(' .

How can I solve this please...

Radgrid rebind issue on filter

Hi Telerik,

I am using Radgrid Q2 2010, VS 2005. I am binding the grid with more than 40000 records. First time i am binding only distinct values in each column, so the number of records is comparatively less. Then when i filter the grid, I perform the filter on the 40000 records, and after filter it may contain a minimum of 35000 records. When i rebind the grid with the filtered result, sometimes it throws this error
" htmlfile: Could not get the value property. Not enough storage is available to complete this operation." Or sometimes the browser is not responding and gets closed.

Please reply me asap. Its a very urgent requirement.

Thanks
