Invalid Value + Red Exclamation mark ????

[du5]

Hi,

There appear a "Invalid Value" and an exclamation mark (!) next to an input textbox when validating my form ????
When i made the first update of an existing record it works fine.
When i do a second update of the appropriate record and change the textbox a received that Invald Value and a red exclamation sign near the textbox ?

What is here going on ?


Greetings,

Eric

Is this an app that you're developing?
Do you have an ErrorProvider component on said form?
