Show/Hide link button controls in Data list control

Question

Hi,

I have a Data List control which displays events. I have 2 functionalities in data list. They are Edit,Copy.

When I click EDIT button, and edit item template is loaded which has an UPDATE button to update the data.

When I click the COPY button, the same edit item template is loaded, which should have a SAVE button (to save the event as a new event).

The problem here is if I click on EDIT I have to display UPDATE Button, If I click on Copy I have to display SAVE button.

How do I know which button is clicked in Item_DataBound Event of Data list.

Can any one please help me in this issue.

Thank you, I appreciate your time.

Hi Jinesh, Thank you for the reply. I am able to capture the command name in ItemCommand, but I want to find out the name of the control in Data List which triggered the post back (whether it is EDIT or COPY) in the Event_ItemDataBound method. Though, I found a solution for this, on page load if it is a postback am using "Request.Params.Get("_EVENTTARGET")" to get the control name and assigning it to a property which I declared initially. In the _ItemDataBound, I am retrieving the property. I am not sure this is a correct way to do it, but this is working. Please let me know, if their is any other way to do this. Thank you, Naresh
