Viewing DataGridBoolColumn

Hmm, i have added a column to my dataset.

    Friend WithEvents dsHistoricViewCol As System.Data.DataColumn
    Friend WithEvents dgtbHistoricViewColStyle As System.Windows.Forms.DataGridBoolColumn

When i do construct a row, i can access to my column:
 nr.Item("View") = False

But when i try resizing i get a non instancied object:
           dgHistoric.TableStyles("HistoricTable").GridColumnStyles("View").Width = 100
Adding the column (named dsHistoricVewCol)...

        Me.HistoricTable.Columns.AddRange(New System.Data.DataColumn() {Me.dsHistoricDateCol,Me.dsHistoricHourCol, Me.dsHistoricRespCol, Me.dsHistoricViewCol})
        Me.HistoricTable.TableName = "HistoricTable"

Adding the column TableStyle to list...

        Me.HistoricTableStyle.GridColumnStyles.AddRange(New System.Windows.Forms.DataGridColumnStyle() {Me.dgtbHistoricDateColStyle, Me.dgtbHistoricHourColStyle, Me.dgtbHistoricRespColStyle, Me.dgtbHistoricViewColStyle})

Standart column table style defenition
        Me.dgtbHistoricViewColStyle.Alignment = CType(resources.GetObject("dgtbHistoricViewColStyle.Alignment"), System.Windows.Forms.HorizontalAlignment)
        Me.dgtbHistoricViewColStyle.FalseValue = False
        Me.dgtbHistoricViewColStyle.HeaderText = resources.GetString("dgtbHistoricViewColStyle.HeaderText")
        Me.dgtbHistoricViewColStyle.MappingName = resources.GetString("dgtbHistoricViewColStyle.MappingName")
        Me.dgtbHistoricViewColStyle.NullText = resources.GetString("dgtbHistoricViewColStyle.NullText")
        Me.dgtbHistoricViewColStyle.NullValue = CType(resources.GetObject("dgtbHistoricViewColStyle.NullValue"), Object)
        Me.dgtbHistoricViewColStyle.TrueValue = True
        Me.dgtbHistoricViewColStyle.Width = CType(resources.GetObject("dgtbHistoricViewColStyle.Width"), Integer)

So coming back to my initial question, why cant I see the datagridboolcolumn ?

Hmm, looks like it was a Visual Studio bug, the resource files has not been updated and the mapping name of my columnStyle was ViewCol instead of View.

1) What are the values for MappingName and Width?

2) Did you set the MappingName for the DataGrid table style?

Well thanks man, it's now working. Dunno why but the UI Editor for the boolcolumn bugged and saved the wrong mappingName.
