Get Data Value From ListView ItemDataBound
提问by Gavin
I'm sure I've done this before but really cant remember how.
我确定我以前做过这个，但真的不记得是怎么做的。
In the ItemDataBound event of a ListView I need to get the actual data value. I cant seem to find it in the ListViewItemEventArgs object that gets passed in.
在 ListView 的 ItemDataBound 事件中，我需要获取实际数据值。我似乎无法在传入的 ListViewItemEventArgs 对象中找到它。
Thanks
谢谢

I think what you're after is the ListViewDataItem.DataItem
我想你所追求的是ListViewDataItem.DataItem

protected void ContactsListView_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
// Display the e-mail address in italics.
Label EmailAddressLabel = (Label)e.Item.FindControl("EmailAddressLabel");
// EmailAddressLabel.Font.Italic = true;
string valueoftheControl = EmailAddressLabel.Text;
/* you have to get the value like this.
If its a dropdown or any other use their
corresponding property to get the value.*/
}
}

Use the ListViewDataItemin the ItemDataBoundevent:
在ItemDataBound事件中使用ListViewDataItem：
protected void yourListView_ItemDataBound(object sender, ListViewItemEventArgs e)
{
ListViewDataItem dataItem = (ListViewDataItem)e.Item;
if (e.Item.ItemType == ListViewItemType.DataItem)
{
YourDataSource yourDataSource= (YourDataSource )dataItem.DataItem;
}
}

protected void Score_ItemDataBound(object sender, Telerik.Web.UI.RadListViewItemEventArgs e)
{
if (e.Item is RadListViewItem)
{
RadListViewDataItem item = e.Item as RadListViewDataItem;
object dataItem = ((System.Data.DataRowView)(((RadListViewDataItem)e.Item).DataItem)).Row.ItemArray[2].ToString();
string raetest = Convert.ToString(dataItem);
}
}
