How Do I Handle This Postback Message?

Question

I am getting the following Postback alert when I use the DotVVM <dot:Validator /> tags in my .dothtml pages. I cannot find any documentation on how to prevent this postback, control a timeout for it or control it's appearance. I am using the <dot:ValidationSummary /> tag at the bottom of my page and do not like the delay the Postback imposes. Any help would be appreciated.

Postback aborted because validation failed.

This happens when DotVVM is in the debug mode. If you didn't have any validator in the page and there was a validation error, you wouldn't notice that - that's why DotVVM displays this popup.

To remove it, you need to set config.Debug = false in DotvvmStartup.cs. You can use the following construct to detect the debug mode based on your build configuration:

private bool IsDebug
{
    get 
    {
#if DEBUG
        return true;
#else
        return false;
#endif
    }
}
