I have a user control with a datagridview to show an address list in a popup, that the user can choose from.
I followed a Microsoft MSDN example. However, when I drag the built usercontrol onto a form, the DataSource property in the property grid of the control remains grayed out. Thus I can't set a datasource property during desgin time.
 
What am I doing wrong?
This is my code:
 
Imports PrismaModel
Imports System.ComponentModel
 
<System.ComponentModel.ComplexBindingProperties("DataSource", "DataMember")> _
Public Class AdressenControl
 
  Public Event AdresDoubleClicked(ByVal adres As Adres)
 
  Public Property DataSource() As Object
    Get
      Return Me.ZaDatagridView1.Datasource
    End Get
    Set(ByVal value As Object)
      Me.ZaDatagridView1.Datasource = Me.ZaDatagridView1.Datasource
    End Set
  End Property
 
  Public Property DataMember() As String
    Get
      Return Me.ZaDatagridView1.DataMember
    End Get
    Set(ByVal value As String)
      Me.ZaDatagridView1.DataMember = value
    End Set
  End Property
 
  Private Sub ZaDatagridView1_CellDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles ZaDatagridView1.CellDoubleClick
 
    If e.RowIndex > -1 Then
      Dim adres As Adres
      Dim list As List(Of Adres) = ZaDatagridView1.Datasource
      adres = list(e.RowIndex)
      RaiseEvent AdresDoubleClicked(adres)
    End If
  End Sub
 
End Class

Hi
 
If you want to set the datasource property then it has to be done on the user control design itself. Not while using.
 
But you can assign it during runtime. Have a public function/property in the user control which helps set the datasource. That you can use from any hosting container like form.
