I want to make a usercontrol which is a combobox but the dropdown will be a grid. So far this is my code and my problem is that the grid wont show.

Namespace myComboBox
    Public Class popUpComboBox
        Inherits System.Windows.Forms.ComboBox

        Protected Overrides Sub OnDropDown(ByVal e As System.EventArgs)
            Dim grid As New System.Windows.Forms.DataGridView

            grid.Width = 1000
            grid.Height = 1000
            grid.Left = Me.Left
            grid.Top = Me.Top + Me.Height

        End Sub

    End Class
End Namespace

In windows application if u want to create user control
develop the application go to properties of the project make it as a class library
and then select start up object as nothing then run the application
it will give u the dll file instead of .exe
you can use this dll as component as user control wherever u want
