i=e.Item.Cells[0].Text;
DataGrid1.SelectedIndex=e.Item.ItemIndex;

this.RRR(i);}
}
public void RRR(string j)
{
if(!db1.IsOpen())
{
db1.DBOpen(); }

TextBox2.Text=(string)SelectReader.GetSqlString(1);
TextBox3.Text=(string) SelectReader.GetSqlString(2);
TextBox4.Text=(string)SelectReader.GetSqlString(4);
TextBox5.Text=(string)SelectReader.GetSqlString(3);

Answer 1

双击datagrid一行，新弹出一个页面
在DataGrid的ItemDataBound事件中处理private void dg_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
e.Item.Attributes["ondblclick"] = "alert('write at here');";
}
}

Answer 2

me.DataGrid1.item(me.DataGrid1.CurrentItem.RowIndex,me.DataGrid1.ColIndex);
