Recreating the RadMaskedTextInput error handling

[Lee]

Hey all,

I'm dense when it comes to xaml, wpf, and telerik. I'm looking to extend a regular Textbox with custom validation logic, which is all well and good. What I now want to do is handle errors, like RadMaskedTextInput does, where I can trip the error state/throw a validation error, have the box outlined red with the red arrow on the top right, and the error tool tip pop up when hovering.

There's good documentation that handles each problem individually, but the matter of tying it all together, and which error handling to choose, is the issue. If I could do the error handling/display of RadMaskedTextInput, or other telerik controls, without needing to use it, that would be great.

Thanks,

Lee

Hello Lee,

You can find a runnable project showing the data validation features described in the help documentation on GitHub.

Thanks Martin,

The root of the issue is my lack of WPF knowledge. I believe what I wanted to do was copy the error styling the telerik controls had rolled into them. Instead I'm using the telerik controls explicitly, and going from there.

Thanks again,

Lee
