	Hi! I have my own class ClsMMTableNode derived from TableNode. Im overriding DrawHandles sub because of drawing my own selection rectangle. I would like to create this behavior: selection rectangle of selected tables is gray and selection rectangle of ActiveItem is blue. How I know in DrawHandles sub if table (me) is ActiveItem in diagram? Now I perform this code: Code Public Overrides Sub DrawHandles(ByVal graphics As MindFusion.Drawing.IGraphics, ByVal color As System.Drawing.Color) Dim LoColor As Color If Me.Parent.ActiveItem IsNot Nothing Then If Me.Parent.ActiveItem.Equals(Me) Then 'me is active selected LoColor = Drawing.Color.Blue Else 'me is not active selected LoColor = Drawing.Color.Gray End If Else 'nothing is selected LoColor = Drawing.Color.Gray End If ... Thx. ...MUDO...

	Hi, If you only need to change the selection rectangle color, set the ActiveItemHandlesColor and SelectedItemHandlesColor propertie. One of these values is passed as the "color" argument of DrawHandles, depending on whether the table is the ActiveItem. I hope that helps, Stoyan
