I have a page based wpf application, where a user enters information and clicks on a "Next" button, and is brought to a new page, passing the information along.  When the second page is reached, I want to dynamically add tab(s), group(s), and wrappanel(s), based on how many inputs they submitted.  I am trying the following, but it is exceptioning out with the following error:

Layout measurement override of element 'Telerik.Windows.Controls.RibbonView.Primitives.RibbonGroupsPanel' should not return PositiveInfinity as its DesiredSize, even if Infinity is passed in as available size.

Code:
             RadOrderedWrapPanel checkpointwrap = new RadOrderedWrapPanel();
            checkpointwrap.Name = "ckwrap";

            RadRibbonGroup checkpointgroup = new RadRibbonGroup();
            checkpointgroup.Name = "ckp_" + "2";
            checkpointgroup.Items.Add(checkpointwrap);
            checkpointgroup.Header = "GroupTest";

            RadRibbonTab checkpointtab = new RadRibbonTab();
            checkpointtab.Name = "CKP1";
            checkpointtab.Items.Add(checkpointgroup);

            this.Grid1.Children.Add(checkpointtab);

Found the issue.  Instead of adding to my Grid, I just needed to add the tab to the ribbonview:

this.radRibbonView.Children.Add(checkpointtab);

Tabs/Groups/Wrappanels are now built dynamically

Hello Ken,

 Yes, you need to add the Tabs to the Ribbon. Please let us know if you have other issues.

Hi,

with last version of controls (2013 Q2) RadRibbonView don't contain a Children properties.
How to add dinamically, in codebihind, a new tab to a RadRibbonView?

Thank's,
marc.

Hi Marcello,

You are right that there is no Children collection exposed by the RadRibbonView control in our latest official release. However, in order to add/remove RadRibbonTabItems at runtime you can use a HierarchicalDataTemplates. The required structure of the hierarchy is the following:
RadRibbonView -> RadRibbonTab -> RadRibbonGroup -> other RadRibbon controls. Hence, you need to implement hierarchy matching this structure. You can take a look at this demo to see how we implemented this structure.

I hope this information will help you. Don't hesitate to ask if you have any other questions.
