Hi Megha,

You can easily get the row of which row is clicked , There are a lot ways to do this.

Eg.
In the ButtonClickedevent in server try one of the following ( applies for all controls events not only for button you can use check box , I already have the sample for button click)

[C#]
Button btn = (Button)sender as Button;
DataGridItem myItem =(DataGridItem) btn.NamingContainer;

//This will return the selected rows index value starts from 0

myItem.ItemIndex;

//also you can use to get some of the key field of that row with the following code

//Here i assume first column will have a unique value so given Cells[0] and in which you can use for your changes in server side.

string rowId;
rowId = myItem.Cells[0].Text;

I guess the above codings should give you some idea

Hi Megha,

As i said before , " this will return the value start from 0" . you can probably use

int something=myItem.ItemIndex;

and this something will be your rowindex

Let me know if this helps
