Can't apply a DataGridTableStyle to a Datagrid

Hello,

I've this code:

    Private Sub BuildDgStyle()
        Dim dgStyle As New DataGridTableStyle
        dgStyle.MappingName = Me.Tabella

        Dim colCodice As New DataGridTextBoxColumn
        colCodice.HeaderText = Me.HeaderCodice
        colCodice.MappingName = Me.CampoCodice

        If Me.MaxCodLenght > Me.HeaderCodice.Length Then
            colCodice.Width = Me.MaxCodLenght + 5
        Else
            colCodice.Width = Me.HeaderCodice.Length + 5
        End If

        dgStyle.GridColumnStyles.Add(colCodice)

        Dim colDescrizione As New DataGridTextBoxColumn
        colDescrizione.HeaderText = Me.HeaderDescrizione
        colDescrizione.MappingName = Me.CampoDescrizione

        If Me.MaxDesLenght > Me.HeaderDescrizione.Length Then
            colDescrizione.Width = Me.MaxDesLenght + 5
        Else
            colDescrizione.Width = Me.HeaderDescrizione.Length + 5
        End If

        dgStyle.GridColumnStyles.Add(colDescrizione)

        Me.dgItems.TableStyles.Add(dgStyle)
    End Sub

And I call that sub from Form_Load. The problem is that vb doesn't apply the style to my grid.
Where's the error

What is Me.Tabella What kind of data are you putting in the DataSource property
J. Aldrin
Me.Tabella is a public property of my Form. It contains the name of the database table.

First I would make sure that the mapping name is getting passed to the tablestyle (go into debug and hover the mouse over it).

Then I would make sure you have your data set to the correct way.

Datasource = dataset
datamember = "tablename"

Also, why are you doing this the hard way you can do it via the designer alot better and faster. click the tablestyles property in the property browser and add a table style and then set the mapping then hit the grid column styles and then add your column styles.

Easy as pie.
