Here is the sample

Hi Georgi,

Thank you for your sample, but it seems not solve my problem...

I'm not using designer, I create buttontool dynamiclly in code behind, which may cause some problems I dont know.

The code i'm using is shown below, do you find any problems? (Sorry about the format, please copy and paste code to VS!)

         private ButtonTool AddRibbonButtonTool(RibbonGroup Group, string key, string caption, object largeImage, object smallImage, string keyTip, Shortcut shortCut, RibbonToolSize ribbonToolSize, string StatusText, string ToolTipText, string workItemStateKey, string workItemCommandKey, bool isFirstInGroup)         {             ButtonTool buttonTool = new ButtonTool(key);             buttonTool.SharedProps.Caption = caption;             if (largeImage != null)                 buttonTool.SharedProps.AppearancesLarge.Appearance.Image = largeImage;             if (smallImage != null)                 buttonTool.SharedProps.AppearancesSmall.Appearance.Image = smallImage;             //buttonTool.SharedProps.KeyTip = keyTip;             if (shortCut != Shortcut.None)                 buttonTool.SharedProps.Shortcut = shortCut;             buttonTool.SharedProps.StatusText = StatusText;             buttonTool.SharedProps.ToolTipText = ToolTipText;             this.UIElements.ToolbarsManager.Tools.Add(buttonTool);// add into toolbarManager.             ButtonTool groupButtonTool = Group.Tools.AddTool(key) as ButtonTool;// add into group, and get the instance

            if (ribbonToolSize != RibbonToolSize.Default)                 groupButtonTool.InstanceProps.PreferredSizeOnRibbon = ribbonToolSize;

            groupButtonTool.InstanceProps.IsFirstInGroup = isFirstInGroup;             groupButtonTool.InstanceProps.KeyTip = keyTip;             return groupButtonTool;         }
