Hi all,

I have a datalist and on clicking a link button i would like a popupcontrol to appear.

With the selection in the popupcontrol, i would then update the datalistitem in the datalist.

However, i have a problem finding the index of the datalist that called the popup.

Hopefully someone can help me.

Don't know if the following solution will work for you, but want to share how I did something similar. 

I recently did something similar but used the DropDown control from the ASP.Net Ajax Toolkit. What I did was to create user control and added a property to the control that will hold the id “key” of the row in my GridView (I didn’t use a DataList, but the similar solution can be used). I then bind the field that has the “id” from my data-source to the control’s property. When I select an option from my DropDown (The ASP.Net Ajax DropDown control will popup a specified Panel with some LinkButtons for the options), I could get the id of the current row and use it to modify the data. In your case you could bind the RowIndex or also a “key”.

Note: In my solution I didn’t want to use the RowCommand event because the DropDown will display a Panel where I have LinkButtons, and I wanted to use the click event of the LinkButton to perform different actions etc.
