Hi, Telerik Team.

I’m using Telerik UI for WinForms 2015 Q1 with a custom theme, and I want the text color to remain black even when the control is disabled. Currently, when Enabled=False, the text automatically becomes gray.

My goal is for the text color to be black in both Enabled and Disabled states.

This already works for RadTextBox, using the HostedTextBoxBase approach from the forum.

However, for the following controls, the text still becomes gray when disabled:

  • RadDropDownList

  • RadDateTimePicker

I already modified the Disabled state in Visual Style Builder and updated elements like RadDropDownTextBoxElement and TextBoxFill(Fill Primitive). I’ve attached my .tssp file.

Could you please review the .tssp and let me know if there is any incorrect setting, or if I’m modifying the wrong element to keep the disabled text color black?

Also, if there is a recommended way to achieve this without using Visual Style Builder (for example programmatically), I would appreciate your guidance.

Thank you.
