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
Next
