We are using Telerik Win forms in our latest project and found almost no documentation what so ever about the rad controls. Still this controls are sometimes a big improvement to the standard Win forms, one good example is the RadComboBox. We used this ComboBoxes to create our own navigation bar in a win form application. Here are the basic steps so you can create your own navigation bar or learn how to use the RadComboBox a little better.
Once you placed the RadComboBox, you will want to fill it. Telerik provides you a perfectly fitting class for this that is called RadComboBoxItem. This object inherits form System.Web.Ui.WebControls so I'm sure you will find whatever you are looking for your ComboBox. To do our navigation bar we will only need 2 properties from this class, RadComboBoxItem.Text and RadComboBoxItem.Tag.
So after this little introduction let's make our navigation bar. We have placed a RadComboBox and a ListView on a form. The ListView already shows folders and files from your local driver and now we want to add the folders visited by the user to our navigation bar. Whenever an event fires do to the user navigating through your ListView you can simply use this code to fill up your navigation bar:
RadComboBoxItem ComboItem = new RadComboBoxItem();
ComboItem.Text = directory.FullName;
ComboItem.Tag = directory;
Being directory a System.IO.Directory class which the user is currently visiting.
