c#里edititemtemplate模板中DropDownList赋值的问题

edititemtemplate模板中为DropDownList动态赋值，但是在整个GridView行里面只有奇数数列有值，所有偶数列的值是空值.... 下面是在RowDataBound里面写的动态获取DropDownList值的过程 if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowState == DataControlRowState.Edit)
{
DropDownList dplist = (DropDownList)e.Row.FindControl("dplDropList");
BLL.ProductTypeBLL productTypeBll = new BLL.ProductTypeBLL();
List<Models.ProductType> list = productTypeBll.GetAllProductType();
foreach (Models.ProductType entity in list)
{
ListItem item = new ListItem(entity.TypeName, entity.Id.ToString());
dplist.Items.Add(item);
}
dplist.DataBind();
}
}

Answer 1

DropDownList tmpDL = (DropDownList)e.Item.Cells[4].Control[1];
string resultString = tmpDL.SelectedValue; //设置断点总是得到tmpDL.SelectedValue是头一条记录
//do update
......

Answer 2

你调试下，再编辑的时候，应该根本不会抽发这时间的
