"Is Nothing" should work for null objects:
If Not objHeader Is Nothing Then
thanks baxatob
I have tried Exists but as its a (Null Object) it will throw an error
This is the code I am using to locate the correct column header name within a datagrid, however some column headers are blank, therefore it throws an error. This is a silverlight grid, so its a bit complex just to get column names.
set objColumnPresenter = objTable.SlObject("ColumnHeadersPresenter")
intColumnCount = objColumnPresenter.ChildCount
ReDim arrColumns(intColumnCount - 1)
For x = 0 to UBound(arrColumns)
set objColumnChild = objTable.Columns.Item(x)
set objHeader = objColumnChild.Header
If objHeader.Exists Then '///PROBLEM OCCURS WHEN HEADER BLANK
arrColumns(x) = objColumnChild.Header
If strSearchCol = objColumnChild.Header Then
intColumn = x
End if
End if

Hi Helen
Thanks for your reply, sorry have only just managed to check it.
'Is Not Nothing' does work some of the time, although not every time for some reason.
If you know anymore ways of checking for a (Null object) then that would be useful. But its not so urgent an issue anymore.
Thanks for your help
Hi Yarnos,
What's the SlFullClassName property of your grid (the objTable object in your code)? Is it a standard Silverlight grid (System.Windows.Controls.DataGrid or its derivative) or a third-party (DevExpress, Telerik, etc.)?
