I am binding to a collection of Business Objects in a GridView (Windows App,
..NET 2.0).

In my Business Object I have a Property that is an ENUM.

I want a Drop down box in the Grid that is Bound to the property that is of
the type of the ENUM.  I want the combo box filled in with the list of ENUM
values.

Does the GridView support this?

Hi,

        You can try something like this.  You need to manually remove the
column from the gridview and add the column back in.   You can see a
complete example here

http://www.vb-tips.com/default.aspx?ID=492bcbbc-f881-45c8-9b3a-62c7a184f472

Here is the code.  I did not set the column the datagridview combo is bound
to. It will show the display member but keep the value member as its value.


        Dim lstEnum As New List(Of enumBindTo)
        Dim arColor() As String
        arColor = KnownColor.GetNames(GetType(KnownColor))

        For x As Int16 = 0 To arColor.GetUpperBound(0)
            Dim cls As New enumBindTo
            With cls
                .EnumValue = x
                .StringValue = arColor(x)
            End With
        Next

        Dim dgvEnum As New DataGridViewComboBoxColumn
        With dgvEnum
            .Width = 150
            .DataSource = lstEnum
            .ValueMember = "EnumValue"
            .DisplayMember = "StringValue"
            .HeaderText = "Color"
        End With

        DataGridView1.Columns.Add(dgvEnum)

The class I used

Public Class enumBindTo

    Private mintEnumValue As Integer
    Public Property EnumValue() As Integer
        Get
            Return mintEnumValue
        End Get
        Set(ByVal value As Integer)
            mintEnumValue = value
        End Set
    End Property

    Private mstrValue As String
    Public Property StringValue() As String
        Get
            Return mstrValue
        End Get
        Set(ByVal value As String)
            mstrValue = value
        End Set
    End Property

End Class
