Is there a way to use the validation functionality of the RadInputManager for the RadTextBox?
I've been trying to implement a "Required" validation for the RadTextBox without having to manually add RequiredFieldValidators, because we have web pages with many RadTextBoxes.
I've been partially succesfull in implementing a own CompositeControl which dynamically adds the RadTextBox and the RequiredFieldValidator. I'm not sure if this is a definite solution because of many problems I encountered. Because of these problems I started researching the RadInputManager as an alternative.
The post on Todd Anglin's blog: http://blogs.telerik.com/toddanglin/posts/08-12-12/Showing_RadToolTip_on_RadInput_input_error.aspx
looks like the solution I need, except that it should work for RadTextBox.
Thanks in advance for your help,
