    I have a problem related with RadNumericTextBox, RadDateInput and RadMaskedTextBox. I use a RadInputManager control, to validate some textboxes (they need to be required), and it works ok on asp:TextBox controls, but on telerik controls it doesn't seem to work. I want to have the same behavior with red textbox border and the yellow triangle with exclamation mark inside if the fields are required. Is there something i have to set on the controls?

    Referring to the knowledge base, "there are two groups of controls which are extended using the RadInputManager. The first are controls which are located directly on the page, such as a normal text box, somewhere on the form. The second are text boxes located in another control - for example a text box nested in a repeater."
    I would suppose that this is an expected behavior -- that RadControls can't be used with RadInputManager.
    You can check the validation of RadNumericTextBox,RadDateInput,RadMaskedTextBox by using javascript as follows.
    function invalidate()
      var tb = $find("<%= RadNumericTextBox.ClientID %>");
      tb._invalid = true;
      return false;
