Different BorderColor while Focused

Hi Alwin,

Currently, the only option for you is to set a custom border color programmatically. I am attaching a sample project to demonstrate this approach.

We will consider supporting the desired behavior by themes in one of our next versions.

Of course this is very old post.

Do you have any elegant solution now to change border  color of text box in focus?

Thanks.

Hi Sateesh,

Now you can change the border color with the following code:

I hope this will be useful. Let me know if you have additional questions.

Hello How would you do it, if you change the border to red, and then return it to normal (RadTextBox.TextBoxElement.Border.ForeColor), regardless of the subject you are in, in my case I am in the Crystal theme, change the color of the border to red becomes super simple, but returning it to normal as the theme applies is complicated, some guide please. note: use vb.net

Hello, Danny,

According to your description, I suppose that you want to change the border's ForeColor property of RadTextBox to red color when some condition is met and to reset the color to its default theme color when the condition is not met. To achieve this you should store the default border color in the Load event of the form which occurs before the form is displayed for the first time and ensure that the theme settings are already applied. As it is not specified in your description which element state you want to use, I prepare a sample example by using the element focus state. The example demonstrates how to change the border color when RadTextBox receives focus and how to reset the border color to its default theme color when the focus is lost:


Another approach I can suggest is to make use of the SetThemeValueOverride method and override the ForeColorProperty for a specific element state without losing the applied style for the rest of the states:


Feel free to use this approach which suits your requirements best. The achieved result is demonstrated in the attached gif file.

I hope this helps. Should you have any other questions, I will be glad to help.

perfect works but in the Dema by Default, but that pqasa in the Crystal themes, there is this does not work, the edge does not return to normal, it is altered

Hello, Danny,

According to the provided information, it is not clear enough what is the exact requirement that you are trying to achieve. I suppose that you use the Crystal theme for your application and when you change the border color of the TextBoxElement you receive double colored border over it, as shown in the following picture:

    

To prevent this, it is necessary to set the TextBoxElement.Border.GradientStyle property to Solid in the GetFocus event:


I suppose this is what you are looking for. If it doesn't, it would be greatly appreciated if you can provide additional information about the exact goal that you want to achieve. 

I am looking forward to your reply.
