Glossary Item Box

The DataItem property is available only during databinding in the ItemDataBound event:

C# Copy Code
protected void RadMenu1_ItemDataBound(object sender, Telerik.WebControls.RadMenuEventArgs e)
   {
       DataRowView dataSourceRow = (DataRowView)e.Item.DataItem;
   }
        
VB.NET Copy Code
Protected Sub RadMenu1_ItemDataBound(sender As Object, e As Telerik.WebControls.RadMenuEventArgs)
   Dim dataSourceRow As DataRowView = CType(e.Item.DataItem, DataRowView)
End Sub 'RadMenu1_ItemDataBound

You should not use it elsewhere. You can use the Value property or Custom Attributes instead.
