Click Event in the Asp.net gridview

Hi All,
I need help for click event in asp.net grid view.
On Row click of the grid view i want to populate data in the another grid by passing the id of the selected row.
I go through the this link http://aspsnippets.com/demos/533/ but it i need optimized code want to avoid lopping through the grid rows.
protected void OnRowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(GridView1, "Select$" + e.Row.RowIndex);
e.Row.ToolTip = "Click to select this row.";
}
}
protected void OnSelectedIndexChanged(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowIndex == GridView1.SelectedIndex)
{
row.BackColor = ColorTranslator.FromHtml("#A1DCF2");
string a= row.Cells[0].Text;
row.ToolTip = string.Empty;
}
else
{
row.BackColor = ColorTranslator.FromHtml("#FFFFFF");
row.ToolTip = "Click to select this row.";
}
}
this code contains loop for checking the selected row which i don't want to do is there any other way to do it.
Thanks in advance.

Actually, there is no need of the loop here. Just remove that and update code like below...

protected void OnSelectedIndexChanged(object sender, EventArgs e)
{
```
   // Get the currently selected row using the SelectedRow property.
   GridViewRow row = CustomersGridView.SelectedRow;
```
row.BackColor = ColorTranslator.FromHtml("#A1DCF2");
string a= row.Cells[0].Text;
row.ToolTip = string.Empty;
}
