I'm using a RadRicjTextBox in a WPF with DataBinding and ValidatesOnDataErrors, and I'm trying to add validation to ensure that the user has acutally typed something into the comment
Here is the XAML snippet...
But I'm not sure how to validate the contents in my IDataErrorInfo code, I can't just check to see if the Response field is empty, because as soon as you type anything, and then delete it, the field contains all the HTML wrappings.
Am I missing something or is there a way to do this, I had thought I should try and convert the HTML to Text somehow and then check, but I don't want that to happen with every key press (I'm also not sure how to go about it
Thanks in advance
