How to hide certain groups displayed in SkinDropDownButtonItem

Ok, thanks!
I have no problem accessing the "Visible" property of the GalleryItemGroup. Works fine.
But i do not want to hide them, just "uncheck" some groups.
Where is the "checked " property located?

You can achieve this by handling the FilterMenuPopup event of a gallery. Then, access menu items via e.FilterMenu parameter and cast them to DXMenuCheckItem. After that, set their Checked property to false. However, your task is not completely clear to me. Would you please describe your scenario and final goal in greater detail so I can provide you with the most suitable solution?

I want to limit the initial list if skins, by only include skins from some groups.
That means setting the "checked" item to false on some groups.
See the attachment. Some groups are checked, some are unchecked.

Thank you for your clarification. As I described in my answer, these items are linked to the visibility of corresponding groups. That is why the best way to uncheck them is to hide unnecessary groups by setting their Visible property to false. From what I gather from your last comment, you want to limit the initial list of skins. The approach from my answer allows you to accomplish this task. If I missed anything important, please correct me. I look forward to your response.

why there is no Gallery in my SkinDropDownButtonItem?my version is v19.1.5. I want to remove some skins too.

Hello Bodong,

SkinDropDownButtonItem has a gallery in its popup. To access that gallery, use the approach suggested by Pavel in one of the comments at How to customize Skin Gallery - Remove / rename skins and groups. For your convenience, I copied his code snippets here:

C#
GalleryControlGallery gallery = ((skinDropDownButtonItem.DropDownControl as SkinPopupControlContainer).Controls.OfType<GalleryControl>().FirstOrDefault()).Gallery;  

Visual Basic
Dim gallery As GalleryControlGallery = ((TryCast(skinDropDownButtonItem1.DropDownControl, SkinPopupControlContainer)).Controls.OfType(Of GalleryControl)().FirstOrDefault()).Gallery  

Let me know if you need any further assistance.

thanks alot. I find a new method to implement it. for example:

C#
SkinHelper.CreateCustomGalleryItem += OnCreateCustomGallerItem;  
private void OnCreateCustomGallerItem(object sender, CreateCustomGalleryItemEventArgs e)  
        {  
            if(e.SkinName.Contains("2013"))  
            {  
                e.GalleryItem = new DevExpress.XtraBars.Ribbon.GalleryItem();  
            }  
        }
