[Solved] Managing the number of items displayed in a RadSplitButtonElement

[Laurent]

Hello,
I am using a RadSplitButtonElement:
DEFINE PRIVATE VARIABLE BtnAnnulerSplit                 AS Telerik.WinControls.UI.RadSplitButtonElement NO-UNDO.

and I would like to control the number of items displayed. If there are more than can fit, display a vertical scrollbar; otherwise, do not.
I have written the following code:

DEFINE VARIABLE oMenu       AS Telerik.WinControls.UI.RadDropDownMenu NO-UNDO.
DEFINE VARIABLE iItemHeight AS INTEGER NO-UNDO.
        oMenu = BtnAnnulerSplit:DropDownMenu.
        iItemHeight = 10.

        oMenu:Maximum = NEW System.Drawing.Size(0, 20 * iItemHeight).

I do have a size, but no vertical scrollbar, which means I can’t see all the items.
Thank you for your feedback

Hello, Laurent,

By default, the drop-down menu is auto-sized, and its height is calculated automatically based on the number of available items and their height. If the items do not fit within the available space, a vertical scrollbar is displayed.

Based on your description, it appears that you would like to set a custom height for the drop-down menu. You can achieve this by using the following code snippet:

 RadDropDownMenuElement popupElement = this.radSplitButton1.DropDownButtonElement.DropDownMenu.PopupElement as RadDropDownMenuElement;
 popupElement.MaxSize = new Size(0, 20 * iItemHeight);
 popupElement.ScrollPanel.MaxSize = new Size(0, 20 * iItemHeight);
 popupElement.MinSize = new Size(0, 20 * iItemHeight);

I hope this information helps. If you have any other questions, do not hesitate to ask.

Hello, Laurent,

I am glad to hear that the suggested solution works for you in OE ABL and that now the RadSplitButton appears as you wish.
