Adding Templates at Runtime

The following help article demonstrates how you can add templates to RadRibbonBar control at runtime, using the RibbonBarTemplateItem.

The RibbonBarTemplateItem should be initialized in the OnInit event of the page. This is needed as the template should be instantiated before the elements of the RadRibbonBar are initialized. The tabs and groups should be dynamically added so that templates can be defined at run time.

<telerik:RadRibbonBar RenderMode="Lightweight" ID="RadRibbonBar1" runat="server" />

protected override void OnInit(EventArgs e)
{
    //RibbonBar properties 
    RadRibbonBar1.Skin = "Default";
    RadRibbonBar1.Width = Unit.Percentage(100);

    //creating RibbonBar tab 
    RibbonBarTab radRibbonBarTab = new RibbonBarTab();
    radRibbonBarTab.ID = "HomeID";
    radRibbonBarTab.Value = "HomeValue";
    radRibbonBarTab.Text = "Home";
    RadRibbonBar1.Tabs.Add(radRibbonBarTab);

    //creating RibbonBar group
    RibbonBarGroup radRibbonBarGroup = new RibbonBarGroup();
    radRibbonBarGroup.ID = "GroupID";
    radRibbonBarGroup.Value = "GroupValue";
    radRibbonBarGroup.Text = "Group";
    radRibbonBarTab.Groups.Add(radRibbonBarGroup);

    //creating RibbonBar button
    RibbonBarButton btnRibbonBarButton = new RibbonBarButton();
    btnRibbonBarButton.ID = "btn1";
    btnRibbonBarButton.Value = "ribbonBtn1";
    btnRibbonBarButton.Enabled = true;
    btnRibbonBarButton.Size = RibbonBarItemSize.Large;
    btnRibbonBarButton.Text = "Ribbon Button";
    radRibbonBarGroup.Items.Add(btnRibbonBarButton);

    //creating RibbonBar template
    RibbonBarTemplateItem radRibbonBarTemplateItem = new RibbonBarTemplateItem();
    radRibbonBarTemplateItem.Template = new RibbonCheckBox("checkbox", "CheckBox Text", false, true);
    //radRibbonBarTemplateItem.Template = new RibbonCheckBox("checkbox", "CheckBox Text", false, false, true);
    radRibbonBarGroup.Items.Add(radRibbonBarTemplateItem);
