datagridview value

thnx madhu and amit....

A little modification in Madhu's post:

use int RowID= e.RowIndex;
instead of RowId = GridView1.CurrentRow.Index;

Rest code is good to go..

I think you are working on a windows application. If it is
This dirty code will give you an idea
//cell click event to
private void GridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
  RowId = GridView1.CurrentRow.Index;
     DataTable dt = new DataTable();
            DataColumn dc = new DataColumn("id");
            DataColumn dc1 = new DataColumn("name");
            DataRow dr = dt.NewRow();          
            dt.Columns.Add(dc); dt.Columns.Add(dc1);                       
            dr["CSID"] = CSGridView1.Rows[RowId].Cells[0].Value;
            dr1["Name"] = CSGridView1.Rows[RowId].Cells[1].Value; //
            dt.Rows.Add(dr);
            dataGridView1.DataSource = dt;
          
}

you can use selectedindex change event of the grid view, and then use that current index to fetch the cell value
