如何找到datalist内部的控件 [英] how to find control which is inside datalist

问题描述

我想找到lable里面的datalist ...我试过下面的代码，但它给出了错误对象引用未设置为对象的实例



protected void DsListHOoutlet_ItemCommand（object source，DataListCommandEventArgs e）



{

foreach（DsListHOoutlet.Items中的var项目）

{

string countryHOout =（（Label）DsListHOoutlet.FindControl（& quot; LblCountryHOoutlet& quot;））。文字;

}

}

i want to find lable which is inside datalist...i have tried following code but it is giving error "object reference not set to an instance of an object"

protected void DsListHOoutlet_ItemCommand(object source, DataListCommandEventArgs e)

{
foreach(var item in DsListHOoutlet.Items)
{
string countryHOout = ((Label)DsListHOoutlet.FindControl("LblCountryHOoutlet")).Text;
}
}

推荐答案

<asp:DataList ID="DataList1" runat="server" RepeatColumns="3" style="z-index: 108; left: 733px; position: absolute; top: 72px" >
          <ItemTemplate><asp:Image ID="uximage" runat="server" /></ItemTemplate>
        </asp:DataList>

'



图片im =（图片）DataList1.FindControl（ uximage）;

im.ImageUrl =Handler.ashx;

'

Image im = (Image)DataList1.FindControl("uximage");
im.ImageUrl = "Handler.ashx";

试试这个.. :)

Try this..:)

foreach(DataListitem item in DataList1.Items)
{
Label lblUser = (Label )item.FindControl("lblLabel");
lblUser .Text= "What ever you Like";
}

标签lblcountryHOout =（标签）DsListHOoutlet.Items [e.Item.ItemIndex] .FindControl（LblCountryHOoutlet）;

string countryHOout = lblcountryHOout.Text;

Label lblcountryHOout = (Label)DsListHOoutlet.Items[e.Item.ItemIndex].FindControl("LblCountryHOoutlet");
string countryHOout = lblcountryHOout.Text;
