要在datagrid的编辑状态下才能显示<EditItemTemplate >模版,findcontrol才能找到控件private void TypeUpdate(object sender, DataGridCommandEventArgs e)//datagrid的update事件
    {
        TextBox tb=(TextBox) e.Item.FindControl("NowName");
        Label lb = (Label)e.Item.FindControl("NowID");
}
我的目的是:输入单价或数量时自动算出总价，赋到另个textbox中。如何实现？
EDIT事件中找到控件，为控件加上属性用Javascript算出来
private void DataGrid1_EditCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
this.DataGrid1.EditItemIndex =  e.Item.ItemIndex ;
BindDataGrid();
TextBox c1 = (DataGrid1.Items[e.Item.ItemIndex].Cells[1].Controls[0] as TextBox);
TextBox c2 = (DataGrid1.Items[e.Item.ItemIndex].Cells[2].Controls[0] as TextBox);
TextBox c3 = (DataGrid1.Items[e.Item.ItemIndex].Cells[3].Controls[0] as TextBox);
c1.ID = "c1";
c2.ID = "c2";
c3.ID = "c3";
c1.Attributes.Add("onkeyup","CountData('"+c1.ClientID+"','"+c2.ClientID+"','"+c3.ClientID+"');");
}<script language="javascript">
function CountData(C1,C2,CtlCountID)
{
var x=0,y=0;
var Ctl1 = document.getElementById(C1);
var Ctl2 = document.getElementById(C2);
var CtlCount = document.getElementById(CtlCountID);
x = Ctl1.value ;
y = Ctl2.value;
CtlCount.value =  x * y;
}
