Change name and width colums on DataGrid

[mi1306]

I want will change name and width colums on DataGrid. Has written the following code all on rules.
Works up to a point 1, but does not want will change columns
Ani ideas?

Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load

dt.Columns.Add(New DataColumn("Col0", GetType(Integer)))
dt.Columns.Add(New DataColumn("Col1", GetType(String)))
dt.Columns.Add(New DataColumn("Col2", GetType(Double)))

Dim i As Integer
For i = 0 To 8
dr = dt.NewRow()
dr(0) = i
dr(1) = "Name" & i.ToString
dr(2) = 10 * i
dt.Rows.Add(dr)
Next i

DataGrid1.DataSource = dv
1.
Dim tableStyle As New DataGridTableStyle
tableStyle.MappingName = "Artikuli"

Dim discontinuedCol As New DataGridBoolColumn
discontinuedCol.MappingName = "Check"
discontinuedCol.HeaderText = ""
discontinuedCol.Width = 50
discontinuedCol.AllowNull = False
tableStyle.GridColumnStyles.Add(discontinuedCol)

Dim column As New DataGridTextBoxColumn

column.MappingName = "ID"
column.HeaderText = "ID"
column.Width = 100
tableStyle.GridColumnStyles.Add(column)

column = New DataGridTextBoxColumn
column.MappingName = "Name"
column.HeaderText = "Name"
column.Width = 1000
tableStyle.GridColumnStyles.Add(column)

column = New DataGridTextBoxColumn
column.MappingName = "Price"
column.HeaderText = "Price"
column.Width = 300
tableStyle.GridColumnStyles.Add(column)

DataGrid1.TableStyles.Add(tableStyle)

End Sub

take a look at thread796-1029632

You look to have most things correct, but are probably missing the table mapping name.

Hello

If column width is your problem, you have to set your datagrid column width BEFORE you set your data mappings.

Thanks

I think this are not the reasons.
I have an example with the same source code that works, but when i put it in my project it does not work from 1. till the end.
