We have a website that runs .NET Framework 2.0 with Ajax version 10618.
But as it is, that is an old version of the dll, so we planned on switching it to the "newest" version of it for the .NET Framework 2.0, the AjaxControlToolkit version 20229.
On our tests, we detected a problem with the ASP control RegularExpressionValidator, which used to work fine with the old version.
Whenever the input to the target control doesn't match the validation, the control displays my text, which is this case is a red asterics dispositioned, like, in the next row, and it displays the following in the control: "-1.7976931348623157e+308".
Theres nothing wrong with the expression because as I said, it works fine with the older version of Ajax, and I couldn't find anything related to RegularExpressionValidators and Ajax versions.
PS: Both the validator and the control are inside an UpdatePanel.
PS 2: With the older version, it would put a 0 in the control and then show me the red asterisc right beside it when the expression wouldn't match.
