Hi All

I have created a custom data converter. What I need to do is to compare the object value to a particular format and show a message to user in case the value is not in correct format.

I tried by writing following code in ValidateCore() function
throw new ConverterException("Input string not in correct format");
But it returns error -" 'IdeaBlade.UI.ConverterException' occurred but was not handled in user code".

How can I do this?

Try looking at this example which displays an error if the FirstName of the Employee does not begin with "Al".
 
Here is the code:
