Dear Sir,

We want extend RadPanelBar and RadPanelBarItem to make them multilingual in accordance with our multilingual framework. But problem is that as soon as we extend these classes it do not render at all even if we do not write single line of code in the extended class.

Same problem is also with other controls like Tab Control.

Please suggest us how to resolve this issue.

Regards
Vinay

Hi Vinay,

What changes to the controls are you making? And what is the exact problem?Is the control rendered at all?

Right now we have not made any changes, just inherited as mentioned below (no code written as of now):
 public class ExRadPanelBar : RadPanelBar
{
// No Code
}

public class ExRadPanelBarItem : RadPanelBarItem
{
// No Code
}

It do not renders at all.

We want to create a new property to make it multilingual. We will pick the text from database based upon the value of the property and display that to user.

Regards
Vinay

Hello Vinay ,

We just tried this code and it turns out that there is a bug in the control when it is inherited. We will try to address this in the upcoming service pack (within the next 2 weeks).

Thank you for your report! Your telerik points has been updated.

All the best,

It looks like the problem has shown up again.  Extending RadPanelBarItem (even with no code added) caused the class not to render.  It was working in WPF UI v2017.3.1018.45 and is not working in v2018.1.122.45
