VB.NET datagrid problem

[Dennis T. Holm]

HEy

Im having problems with setting the width of my columns of my datagrid.
Here's the code

resultatGrid.DataSource = getFirms(0) // gets metaData from database

Dim tableStyle As New DataGridTableStyle

tableStyle.PreferredColumnWidth = 100

tableStyle.RowHeadersVisible = False

tableStyle.MappingName = "firmaer"

resultatGrid.TableStyles.Clear()

resultatGrid.TableStyles.Add(tableStyle)

Dim colStyle As GridColumnStylesCollection =
resultatGrid.TableStyles(0).GridColumnStyles

colStyle.Item("FirmaID").Width = 0

colStyle.Item("Firma Navn").Width = 200

colStyle.Item("Adresse").Width = 100

colStyle.Item("Post nr").Width = 100

colStyle.Item("By").Width = 150

colStyle.Item("CVR nr").Width = 150



I get an exception when using the colStyle.Item() commands ... it should
work but it doesnt --

I get the following exceptoin: System.NullReferenceException

Object reference not set to an instance of an object ..

I think the culprit here is: resultatGrid.TableStyles.Clear()

Please comment this line and try again.

Let me know the results.

cheers!
