We upgraded from 9.1 to 10.2 version. While dragging and dropping usercontrol it gives error.
Failed to create component 'UltraList'. The error message follows:
'System.Null ReferenceException: Object reference not set to an instance of object.
I removed all 9.1 assemblies from GAC and only have 10.2 in it ..
Is infragistics backward compatible ??
Hi,
NetAdvantage should be backward compatible with older versions.
There is no "UltraList" component that I am aware of. Are you sure that's the exact error message?
Is this an existing project or a new one?
Did you replace the project references?
Have you updated the toolbox?
What controls is your UserControl using?
