Changing disabled color

[Dave]

I have a "blueprint" style app with white buttons on a blue background.  When those buttons are in the disabled state, they switch to the default light grey masking which is not very different.

without changing the theme, can I change the "Disabled Color Mask" of a Telerik control like a button on a per-control basis?

Thanks,
Dave

Hi Dave,

Thank you for writing.

One way to accomplish your task is to use the Visual Style Builder tool and modify the theme. With this approach, however, you will change the disabled back color for all the controls which are using your theme. As I understand you would like to do this on a control basis. In this case, you can refer to the SetThemeValueOverride API: https://docs.telerik.com/devtools/winforms/telerik-presentation-framework/override-theme-settings-at-run-time.

For a drop-down button, you can change its disabled back color this way: 

this.radDropDownButton1.DropDownButtonElement.SetThemeValueOverride(Telerik.WinControls.Primitives.FillPrimitive.BackColorProperty,
    Color.Red, "Disabled", typeof(Telerik.WinControls.Primitives.FillPrimitive));

I hope this helps. Let me know if you have other questions.

Regards,
Hristo
