Is there a way to make the validation error message for input controls in general (WatermarkedTextBox, NumericUpDown, MaskedInputs etc) appear on focus of the field? By default it appears on hovering over the small triangle in the upper-right corner of the control, when it's in the error state. This however is pretty hard for users to figure out and also sometimes to correctly "hit" with the mouse cursor.

Thanks!

Hello Ken,

There is no easy way to achieve the desired approach. You need to modify the ValidationErrorTemplate to uses Popup instead of Tooltip and then apply it on desired controls. After-that you need to apply this error template for every input as follow:

<Style TargetType="telerik:RadWatermarkTextBox" BasedOn="{StaticResource RadWatermarkTextBoxStyle}">
       <Setter Property="Validation.ErrorTemplate" Value="{StaticResource ValidationErrorTemplate}" />
</Style>
 
<Style TargetType="TextBox" BasedOn="{StaticResource TextBoxStyle}">
      <Setter Property="Validation.ErrorTemplate" Value="{StaticResource ValidationErrorTemplate}" />
</Style>

I created a sample demo how this should looks like. I hope this helps.
