Along with the above warning, I also get the following message: "This can occur if there is a compilation error in the WebSite, or the web.config file is missing."
Does anyone know what to do to resolve this warning? I do have a web.config file, and I'm just dropping an UltraChart on my Web Form. I am using VS Studio 2008 (VB) on Vista 32-bit business, and I just downloaded and installed the latest version of Infragistics yesterday (12-10-2008).
try viewing the markup for that .aspx page. you should find a line like <igchartprop:GradientEffect /> ... make sure it's not <Infragistics.UltraChart.Resources.Appearance.GradientEffect /> because that is an error that sometimes pops up.
you could also try removing that line entirely to work around the problem...
