&lt;/asp:TemplateField&gt;

For Generating row number DataGridView using c# you can use RowPostPaint event of DataGridView

<pre><code> private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
 {
 // get the row number in leading zero format, 
 // where the width of the number = the width of the maximum number
 int RowNumWidth = dataGridView1.RowCount.ToString().Length;
 StringBuilder RowNumber = new StringBuilder(RowNumWidth);
 RowNumber.Append(e.RowIndex + 1);
 while (RowNumber.Length &lt; RowNumWidth)
 RowNumber.Insert(0, "0");

 // get the size of the row number string
 SizeF Sz = e.Graphics.MeasureString(RowNumber.ToString(), this.Font);

 // adjust the width of the column that contains the row header cells 
 if (dataGridView1.RowHeadersWidth &lt; (int)(Sz.Width + 20))
 dataGridView1.RowHeadersWidth = (int)(Sz.Width + 20);

 // draw the row number
 e.Graphics.DrawString(
 RowNumber.ToString(), 
 this.Font, 
 SystemBrushes.ControlText, 
 e.RowBounds.Location.X + 15, 
 e.RowBounds.Location.Y + ((e.RowBounds.Height - Sz.Height) / 2));
 }
</code></pre>

Right Click on the DataGridView, go through Properties. Then you will get a window like below. Go through the events in the top of the properties you can see several events that can be handled by the DataGridView.Select the RowPostPaint and double click on the right side will create an event on code behind.

You can use the CurrentRow property of the Data Grid

eg. like to change the back color, as follows:

<pre><code>myDataGrid.CurrentRow.DefaultCellStyle.BackColor = Color.Yellow;
</code></pre>

hope it vl b useful to you kitty...
