Gallery item for which to redraw context buttons.


The RefreshContextButtons method raises the GalleryControl.Gallery.ContextButtonCustomize event, and redraws context buttons in the specified gallery item.

The code below shows how to update a context button’s check state when a galery item’s check state changes, and vice versa. It is assumed that gallery items are associated with data items using the Tag property.

using DevExpress.Utils;
using DevExpress.XtraBars.Ribbon;
using DevExpress.XtraBars.Ribbon.Gallery;

galleryControl1.Gallery.ItemCheckedChanged += Gallery_ItemCheckedChanged;
galleryControl1.Gallery.ContextButtonCustomize += galleryControl1_Gallery_ContextButtonCustomize;
galleryControl1.Gallery.ContextButtonClick += galleryControl1_Gallery_ContextButtonClick;

private void Gallery_ItemCheckedChanged(object sender, GalleryItemEventArgs e) {
    ((DataItem)e.Item.Tag).IsChecked = e.Item.Checked;
    (e.Gallery as GalleryControlGallery).RefreshContextButtons(e.Item);
private void galleryControl1_Gallery_ContextButtonClick(object sender, ContextItemClickEventArgs e) {
    GalleryItem galleryItem = e.DataItem as GalleryItem;
    galleryItem.Checked = !galleryItem.Checked;
private void galleryControl1_Gallery_ContextButtonCustomize(object sender, GalleryContextButtonCustomizeEventArgs e) {
    CheckContextButton check = e.Item as CheckContextButton;
    if (check == null) return;
    DataItem data = (DataItem)e.GalleryItem.Tag;
    check.Checked = data.IsChecked;
public class DataItem {
    public bool IsChecked { get; set; }
