Accessing the full DataRow from the DataSource in a ListView ItemDataBound event handler

问题

Is it at all possible within a ListView ItemDataBound event handler to gain access to the full DataRow for that event? I need to do a lot of processing for the entire row on binding, but using data item values in the datarow that I am not actually using in the display itself.

回答1:

Try this

DataRowView dr = (DataRowView)DataBinder.GetDataItem(e.Item);

using dr.Item.ItemArray you can access the entire row.

回答2:

Perhaps try to use the ListViewDataItem property to access the properties of the underlying data object to which the object is bound. The ListViewDataItem property is only available during and after the ItemDataBound events of the control and usually corresponds to a record in your data source object.

Below is an example.

protected void listProducts_ItemDataBound(object sender, ListViewItemEventArgs e)
{
  if (e.Item.ItemType == ListViewItemType.DataItem)
  {
    ListViewDataItem dataItem = (ListViewDataItem)e.Item;
    string prodtype = (string)DataBinder.Eval(dataItem, "ProductType");
    // ...
  }
}
