Ribbon Creator – 4: RadioButtonGroup and ToggleButton - RevitNetAddinWizard & NavisworksNetAddinWizard

Let’s see how to create RadioButtonGroup and ToggleButton items using RevitAddinWizard.

After the Ribbon Creator tool of the Revit Addin Coder is clicked, the Ribbon Creator window will appear. Then we can indicate a RadioButtonGroup is going to be created in a panel of interest through specifying Begin as the first Item, End as the last Item, and ToggleButton items in between.

It is not necessary to specify Text, Tooltip, Image or Command for the RadioButtonGroup as it does not have a look or an action at all though the RadioButtonGroup or its data class RadioButtonGroupData still supports these properties someway. ToggleButton supports all these properties and really use them. Since ToggleButton only has chances to show large images, please remember to pick up a 32x32 pixels bitmap for each of them so that their look in the Revit Ribbon can be good.

After the OK button is pressed, the following code will be created:

        public void AddRibbonItemsToRibbonPanel(RibbonPanel panel)
        {
            string assemFullName = Assembly.GetExecutingAssembly().Location;
            string assemPath = Path.GetDirectoryName(assemFullName);

            RadioButtonGroupData cnt1Panel_grp1Data = new RadioButtonGroupData("cnt1Panel_grp1");
            RadioButtonGroup cnt1Panel_grp1 = panel.AddItem(cnt1Panel_grp1Data) as RadioButtonGroup;

            ToggleButtonData cnt1Panel_grp1_item1Data = new ToggleButtonData("cnt1Panel_grp1_item1", @"Option1", assemFullName, "RevitAddinCSProject.ExtCmd3");
            ToggleButton cnt1Panel_grp1_item1 = cnt1Panel_grp1.AddItem(cnt1Panel_grp1_item1Data);
            cnt1Panel_grp1_item1.ToolTip = @"Option 1 of RadioButtonGroup";
            cnt1Panel_grp1_item1.LargeImage = BmpImageSource(@"RevitAddinCSProject.Resources.BigC.bmp");

            ToggleButtonData cnt1Panel_grp1_item2Data = new ToggleButtonData("cnt1Panel_grp1_item2", @"Option2", assemFullName, "RevitAddinCSProject.ExtCmd4");
            ToggleButton cnt1Panel_grp1_item2 = cnt1Panel_grp1.AddItem(cnt1Panel_grp1_item2Data);
            cnt1Panel_grp1_item2.ToolTip = @"Option 2 of RadioButtonGroup";
            cnt1Panel_grp1_item2.LargeImage = BmpImageSource(@"RevitAddinCSProject.Resources.BigD.bmp");

        }

        public static System.Windows.Media.ImageSource BmpImageSource(string embeddedPath)
        {
            Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(embeddedPath);
            var decoder = new System.Windows.Media.Imaging.BmpBitmapDecoder(stream, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
            return decoder.Frames[0];
        }

If some extra code is added to the same External Application:

                RibbonPanel panel = _cachedUiCtrApp.CreateRibbonPanel(Guid.NewGuid().ToString());
                AddRibbonItemsToRibbonPanel(panel);
                panel.Name = "ABC_APP3_PNL2";
                panel.Title = "Buttons created by the RevitAddinWizard";

something like the following will be added to the Revit Ribbon (depending on what the specified images really look like):

As can be seen, all the images of the ToggleButton items have been changed to something else other than the default image provide by the Ribbon Creator.
