    We have recently upgraded our web application to .net 4 from .net 2, and from Visual Studio 2005 to VS 2010. Then we get trouble with the licensing of the webchart, webgrid and webinput of ComponentOne.

    We are still using the version 2.0 of C1 for these components. When we open an aspx in VS 2010 we get this message -> image C1_aspx_license

    During the execution of the website, we have an another message saying it's just an evaluation version -> image c1_trial_version.
    This last one, appears only for the webchart, it will be annoying for the users.

    We have a license key of this format: XXXXXXX-XX-XXXXXX, but the license activation program needs a key of this format: XXXXXXX-XX-XXXXXX-XX-XXXXXXX

    What's the solution to correctly license our product ? or is there any patch for Net 4/VS2010 ?

    Hello Fabrice,

    It seems that license is not activated on your machine so could you let me know whether you are trying to activate it by right-clicking on the control or using C1LicenseActivation utility ?
    If you are using first option, then it should not show 25 digit format and if you are using the later one, then you may add 0 at the end of the key to make it 25 digit key.

    However, if the issue persists, then I would suggest you send me your serial key along with your details and the build of controls which you are using on our support portal( so that I can check and can assist you further.
