How to theme an inherited control

[Andrei]

Hello.

I need to extend RadTextBoxControl element by inheritance. Basically I need to add IsRequired property (this is simple).

Next I need to be able to see the control in Visual Style Builder and define how it will look when this IsRequired property is set to true.

 

I could not get this information from documentation.

Thank you!

Hi Andrei,

Thank you for writing.

Visual Style Builder is a prebuilt application, and this is why this scenario is not supported (the controls are not dynamically loaded). In this case, you will need to style your custom controls in the code. 

Please do not hesitate to contact us with any additional questions or concerns.

Thank you for prompt reply.

Do you have an example or documentation about how to style control in code?

Hello Andrei,

We do not have such example, generally, you will need to set the same properties as in Visual Style Builder but access them in code. If you have something specific in mind just let me know and I will suggest a solution. 

Actually, you can edit the custom controls at design time as well, but I believe that this is not suitable for you since you will need to change each control separately.

Let me know if you need further assistance.
