sorry for my english, but I need  help ;-).


I have download the last Version 4.22.3616.29532. But where is the property Selection.BackColor; Selection.Border, Selection.FocusBackColor ?

If i use this version 4.22.3606.15103,  i can find this properties.


I have a grid control on a form. If i click on this grid the form must be closed, but there is a error.


 Private Sub DataGridView1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseClick


End Sub

1. You must cast grid.Selection to SelectionBase class to access these properties.

This is because i extracted interface IGridSelection from SelectionBase

Wow, thanks for this fast support.  Now it works :-)

Have you an idea for my problem 2 ?

Thank you very much

I don't know. It may have to do something with threading, if you use threads.   Too little information to be able to understand.

Thanks for you reply,

no, i dont use threads. here, you can try it. Its all. If you click on this grid, there is the error, i posted before.

Imports SourceGrid

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim nGrid As New SourceGrid.Grid

        AddHandler nGrid.MouseClick, AddressOf Grid_MouseClick

        nGrid.Dock = DockStyle.Fill


    End Sub

    Private Sub Grid_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)


    End Sub

End Class

Thank you, for you help.
