  what i did When delete button press its goes  rowcommand event then i check is it delete button press. then i re -create the datasource which not included the deleted row and rebind the gridview. but Now i want to delete the record also from the database. Thats why i want a confirmation dialog box for deleting the record from the database.

  Here Is my Code

  protected void gvRoomList_RowCommand(object sender, GridViewCommandEventArgs e)
      {
          if(e.CommandName == "Delete")
          {
              int ID;
              ID = Convert.ToInt32(gvRoomList.DataKeys[Convert.ToInt32(e.CommandArgument)]["ID"]);
             DeleteRoom(ID);
          }
      }
      protected void DeleteRoom(int ID)
      {
          try
          {
              if (this.ViewState["RoomList"] != null)
              {
                  DataTable dtRoom = new DataTable();
                  DataRow dr = null;
                  Boolean flag = false;
                  int Counter = 0;
                  dtRoom.Columns.Add(new DataColumn("ID", typeof(string)));
                  dtRoom.Columns.Add(new DataColumn("RoomID", typeof(string)));
                  dtRoom.Columns.Add(new DataColumn("RoomNamn", typeof(string)));
                  dtRoom.Columns.Add(new DataColumn("Kontor", typeof(string)));
                  dtRoom.Columns.Add(new DataColumn("Datum", typeof(string)));
                  dtRoom.Columns.Add(new DataColumn("Fran", typeof(string)));
                  dtRoom.Columns.Add(new DataColumn("Till", typeof(string)));
                  dtRoom.Columns.Add(new DataColumn("HuvudRum", typeof(string)));
  
                  for (int i = 0; i < gvRoomList.Rows.Count; i++)
                  {
                      if (Convert.ToInt32(gvRoomList.Rows[i].Cells[0].Text) != ID)
                      {
                          dr = dtRoom.NewRow();
                          dr["ID"] = Counter.ToString();
                          dr["RoomID"] = gvRoomList.Rows[i].Cells[1].Text;
                          dr["RoomNamn"] = gvRoomList.Rows[i].Cells[2].Text;
                          Response.Write("space"+gvRoomList.Rows[i].Cells[3].Text);
                          if (gvRoomList.Rows[i].Cells[3].Text == "&nbsp;")
