Add Custom Items in RadRibbonBarGroup "Add an Item" list

[Manish Mishra]

   I have made my custom ribbon bar like this:
  

public class TMRibbonBar:RadRibbonBar
{
}

in similar fashion, I have made my custom buttons ie.RadButtonElement, RadCheckBoxElement.
What I want is how can I add a button of my own in the "Add an Item" option of "Right Click - Context Menu" of "RadRibbonBarGroup". I mean, my custom button should appear in the list to be selected.

I can add my custom button in the RadRibbonBarGroup dynamically, but how can I do it through the UI?
I hope am not raising a totally invalid requirement.

Hello Manish,

Thank you for writng.

Extending the designer of RadRibbonBar is not an easy task as the control design time is very complex. To handle all cases you will have to override approximately 15 classes. Instead, I will suggest that you add a regular button in design time and then just open the Designer file and replace the type from RadButtonElement to your CustomButtonElement. 

I hope this helps.

All the best,
