DropDownList size/length/displayed item count (Solution)

[Holger Boskugel]

Hello,

I looked sometimes for a solution to change the count of items displayed in the Popup of the RadDropDownListEditorElement.

My solution now is:

Use of EditorRequired event from RadPropertyGrid, Setting the editor to RadDropDownListEditor. Getting the EditorElement as RadDropDownListEditorElement and define the MinSize of Popup as follows:

RadDropDownListEditor editor = new RadDropDownListEditor();
RadDropDownListEditorElement element = editor.EditorElement as RadDropDownListEditorElement;

element.Popup.MinimumSize = new System.Drawing.Size(element.Popup.MinimumSize.Width,
                                       element.ItemHeight * 10);

editor.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;
e.Editor = editor;

where as 10 ist the count of items to be displayed.
