Hi Erwin,

I am not sure what you mean here. Can you give me more details regarding your form structure so that I could try to find a suitable solution?

Hello Erwin,

Indeed in the case of having a large number of controls, applying this will require an extra effort. Until this is resolved, what else you could try is to create a custom class that derives from our controls and apply the workaround in the constructor. Then you can replace our controls with custom ones. This will make it easier to apply the changes to all controls.

Hello Erwin,

Thank you for reporting this.

As a workaround, you can add 1 px Padding to the RadListView (or RadTreeView) control.

public RadForm1()
{
    InitializeComponent();
    this.radListView1.Padding = new System.Windows.Forms.Padding(1);
    this.radTreeView1.Padding = new System.Windows.Forms.Padding(1);
}
