Handling OnDblClick Event of GridViewRow

I have a GridView that displays a list of names. On double-clicking a name, the name needs to be set in a textbox. This needs to happen w/o any postback

The RowCreated event of GridView should add a javascript event handler for the OnDblClick event as follows: ASPX Page:

<asp:TextBox ID="txtSearch" runat="server"/>
<asp:GridView ID="gvMain" runat="server" AutoGenerateColumns="false"
	 OnRowCreated="gvMain_RowCreated">
	<Columns>
	    <asp:BoundField HeaderText="Name" DataField="Name" />
        </Columns>
</asp:GridView>

RowCreated Event Handler:

protected void gvMain_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes.Add("OnDblClick", 
			    "setSearch(" + e.Row.RowIndex + ");");
    }
}

The Javascript for the SetSearch() is below:

<script language="javascript" type="text/javascript">

    function setSearch(row) {
        var tbl = document.getElementById("gvMain");
        var txt = document.getElementById("txtSearch"); 
        txt.value = tbl.rows[row+1].cells[0].innerText;
    }

</script>

Since GridView is rendered as table, the individual cell can be accessed as tbl.rows[rowIndex].cells[cellIndex].innerText
