Solution 1

GridView1_RowDataBound method would get executed for every row in your gridview. Thus, if you have 3 rows then this method would be executed 3 times and thus Response.Write would happen 3 times.

A simple DEBUG could have led to this. :)

As Sandeep said Response.Write will happen three times in Rowdatabound event.
If you don't want it three times just place a label control to get the column name.
or
Write the code in pageload event to get the column name.

protected void Page_Load(object sender, EventArgs e)
       {
           DataSet dssa = (DataSet)Session["dt"];
        string sr = dssa.Tables[0].Columns[2].ColumnName;
        Response.Write(sr);
        }
