Finding the the control which is inside a RadGrid that caused a postback

[Lakshman Venkat]

Here is the scenario. I have radgrid which has a Gridbutton as one of the 

colum.When the user click on that button i redirect them to a different page for 

editing. It works fine since i trap the ItemCommand event. But I am wondering is 

there a way I cab get the Control/Id of the control which caused the 

postback in the Page Load rather than the ItemCommand event so that way I 

can skip some of the page_life cycle methods and straight take them to the edit 

page. I am not able to do this if the user clicks a regular button whcih is part 

of the page. but I am not able to get the control/controlid which is inside the 

radgrid which caused the postback. Appreciate any help.


Here is my grid definition

                    <telerik:RadGrid

Hi Lakshman,

In order to track the button click on Page_Load, I would suggest that you use GridTemplateColumn with a Button in the ItemTemplate. Then on Page_Load the request event target will contain the ID of this button.
ANother option is to use GridHyperLinkColumn and set its NavigateUlr property so the use is automatically redirected to the edit page.

Check it out and let me know if this works for you.

Best wishes,
