Hi You can use GridView OnSelectedIndexChanged Event. Suppose this is your grid view code : asp : GridView ID =GridView1 runat =server HeaderStyle-BackColor =#3AC0F2 HeaderStyle-ForeColor =White AutoGenerateColumns =false OnSelectedIndexChanged = OnSelectedIndexChanged> Columns > asp : BoundField DataField =Name HeaderText =Name ItemStyle-Width =150 /> asp : TemplateField HeaderText =Country ItemStyle-Width =150> ItemTemplate > asp : Label ID =lblCountry runat =server Text =' # Eval(Country) %> '> asp : Label > ItemTemplate > asp : TemplateField > asp : ButtonField Text =Select CommandName =Select ItemStyle-Width =150 /> Columns > asp : GridView > Then your code will be like this : protected void OnSelectedIndexChanged( object sender EventArgs e) { //Accessing BoundField Column string name = GridView1.SelectedRow.Cells[0].Text; //Now Here You Can Add This Name Value in ListBox. } So use Same logic.
