Thank you Avnish, but this will not solve the qustion onhand. On the same cell (amongst other 10 cells in a datalist) I have label1 and textbox1 and command 1. I want to click on commans1 click event and want it to display the value in textbox1 of that specificly selected cell. so I am not in the selectedvalue stage here, I am interpreting values withing the cell itself. Hope this clarifies it more.
All reseraches I am making are pointing to this type of solution
((TextBox)DataList.Items(item_index).FindControl("StudentID")).Text;
HOw can I get this item_index valu whilst I a m in the cell

Thank you Avinsh the post helped and fixed what I was looking for. I have another question in a different post, maybe you can help me figure this out
