问两个关于DataList的问题
因为刚学DataList,用下来有2个问题
protected void DataList1_EditCommand(object source, DataListCommandEventArgs e)
{
this.DataList1.EditItemIndex = e.Item.ItemIndex;
this.DataBindToDataList();
ProvinceOper oper1 = new ProvinceOper();
((DropDownList)e.Item.FindControl( "DropDownList1 ")).DataSource = oper1.GetAllInfo().Tables[ "province "];
//((DropDownList)e.Item.FindControl( "DropDownList1 ")).DataValueField = "proID ";
//((DropDownList)e.Item.FindControl( "DropDownList1 ")).DataTextField = "proName ";
//((DropDownList)e.Item.FindControl( "DropDownList1 ")).DataBind();
}
为什么取不到DropDownList1,取的的是null,而在
<EditItemTemplate>
<asp:Label ID= "Label1 " runat= "server " Text= "Label "> </asp:Label>
<br />
<asp:DropDownList ID= "DropDownList1 " runat= "server ">
</asp:DropDownList> <br />
<asp:DropDownList ID= "DropDownList2 " runat= "server ">
</asp:DropDownList>
<asp:Button ID= "Button1 " runat= "server " Text= "保存 " />
<asp:Button ID= "Button2 " runat= "server " Text= "返回 " />
</EditItemTemplate>
还有就是 <%# DataBinder.Eval(Container.DataItem, "gender ") == "True " ? "男 " : "女 "%> 为什么显示出来的全是女?
------解决方案--------------------如果想得到EditItemTemplate的内容,应该是在UpdateCommand事件和DeleteCommand事件中得到
