我有Datalist,在其中面板和内部面板标签,我想在datalist中的面板内找到标签。我做了我的代码,但它没有用好
protected void DataList1_ItemDataBound(object sender,DataListItemEventArgs e) {
Label LblHead = e.Item.FindControl("Label1") as Label;
string LanguageID = Globals.GetSuitableLanguage(Page);
if (LanguageID == "ar")
{
LblHead.Attributes.Add("CssClass", "hed_logo2");
}
}

添加以下检查,
if (e.Item.ItemType == ListItemType.Item ||
e.Item.ItemType == ListItemType.AlternatingItem)
{
// your code here
}

此代码应该可以在我的本地测试:
protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Panel panel1 = e.Item.FindControl("Panel1") as Panel; //assume your panel name is Panel1
if (panel1 != null)
{
Label LblHead = panel1.FindControl("LblHead") as Label;
if (LblHead != null)
{
string LanguageID = Globals.GetSuitableLanguage(Page);
if (LanguageID == "ar")
{
LblHead.Attributes.Add("CssClass", "hed_logo2");
}
}
}
}
}
