You need to create a DataGridTableStyle Type object and DataGridColumnStyle Type object and set its properties

eg.

        Dim ts1 As New DataGridTableStyle
        ts1.MappingName = "MyTable" 'The table underlying the DataGrid

'Setting Column Width
        Dim Col As New DataGridTextBoxColumn
        Col.MappingName = "Col1" 'The Column you need to format
        Col.HeaderText = "Title of Col1"
        Col.Width = 150 'This will set the Width of the Column
        ts1.GridColumnStyles.Add(Col)

'Hiding a Column
        Dim Col As New DataGridTextBoxColumn
        Col.MappingName = "Col2" 'The Column you need to Hide
        Col.HeaderText = ""
        Col.Width = 0 'This will Hide the Column
        ts1.GridColumnStyles.Add(Col)

Then Don't Forget to add the Style to the Grid

DataGrid1.TableStyles.Add(ts1)


Alternately you can hide the column of underlying Table use:

DataGrid1.Tables("MyTable").Columns(Col2).ColumnMapping=MappingType.Hidden

Thanks for that. I'm using the following but all the columns show up as EMail. What am I doing wrong?

 Dim ts1 As New DataGridTableStyle()
            Dim Col As New DataGridTextBoxColumn()

            ts1.MappingName = "Providers"

            Col.MappingName = "ReferralServiceProviderIDAuto"
            Col.HeaderText = ""
            Col.Width = 0
            ts1.GridColumnStyles.Add(Col)
            Col.MappingName = "ProviderName"
            Col.HeaderText = "Name"
            Col.Width = 100
             ts1.GridColumnStyles.Add(Col)
            Col.MappingName = "Address"
            Col.HeaderText = "Address"
            Col.Width = 100
            ts1.GridColumnStyles.Add(Col)
            Col.MappingName = "City"
            Col.HeaderText = "City"
            Col.Width = 100
            ts1.GridColumnStyles.Add(Col)
            ts1.GridColumnStyles.Add(Col)
            Col.MappingName = "ContactPerson"
            Col.HeaderText = "ContactPerson"
            Col.Width = 100
           ts1.GridColumnStyles.Add(Col)
            Col.MappingName = "Phone"
            Col.HeaderText = "Phone"
            Col.Width = 100
            ts1.GridColumnStyles.Add(Col)
            Col.MappingName = "EMail"
            Col.HeaderText = "EMail"
            Col.Width = 100
            ts1.GridColumnStyles.Add(Col)

            Grid_SearchResult.TableStyles.Add(ts1)

U can hide a column by setting its width to 0

DataGrid1.TableStyles(0).GridColumnStyles(0).Width = 0  // This will hide your ProviderName column ( first column)


U can follow the following link

You are not Resetting the Object Reference for Col

After each

ts1.GridColumnStyles.Add(Col)

Insert a Line

Col = New DataGridTextBoxColumn()
