Problem is at this line

C#

GridView1.Rows[Convert.ToInt32(e.CommandArgument)].Cells[2].Text

Check that GridView1.Rows contains that many rows. It seems that it does not. For example Convert.ToInt32(e.CommandArgument) is returning 2 but the GridView1 does not contain two rows.

Check the value of Convert.ToInt32(e.CommandArgument) and fix it

Solution 1

C#

MessageBox.Show(e.CommandArgument);

C#

//row number is:e.CommandArgument+1
//cell number is：3
MessageBox.Show(GridView1.Rows[Convert.ToInt32(e.CommandArgument)].Cells[2].Text);

debug the previous code and paste the result to me .
