To reproduce: - Run the attached project and show the popup in the "mc" column. The custom editor contains 3 textboxes and despite that the SizingType is set to Auto the textboxes are having smaller than their desired height. Workaround: - Set the textbox Margin instead of setting the CellPaddingProperty.
Yes, this works as well. What I have meant is to set the margin of the text box element: var num1 = new RadTextBoxControlElement(); num1.Margin = new Padding(3);
Works fine. To be exact, one should use MarginProperty, rather than CellPaddingProperty (not margin) SetValue(GridLayout.MarginProperty, new Padding(3))
