BannerTextInfo error in Visual Studio Designer

I am in the process of updating our Essential Tools components prior to a final phase of testing and release. I have just upgraded from version 6.302.1.8 to 6.403.0.15 (I appreciate that we are several versions behind the current). If I start with a blank form with a text box and add a BannerTextInfo component and attempt to set the banner text, the IDE responds with the following error message: "Code generation for property "BannerText" failed. Error was "BannerTextInfoTypeConverter" is unable to convert "Syncfusion.Windows.Forms.BannerTextInfo" to "System.ComponentModel.Designer.Serialization.InstanceDescriptor".
I am investigating upgrade to the most recent version available, but in the meantime can you confirm:
1. Is this a known problem with version 6.403.0.15 and are there any known workarounds?
2. Is the problem fixed in a later version of Essential Tools?
3. Is the problem caused by anything environmental on my PC or to do with the way I have installed Essential Tools?

This is a critical problem for us as over half of our forms use the bannertextinfo component an the problem is preventing the designer from loading for each of them.

Thanks for your help

I appear to have fixed the problem. No quite sure how, but the steps I followed were:
1. Uninstalled Essential Tools
2. Re-installed Essential Tools
3. I reset the toolbox from within Visual Studio 2005.
4. Re-initialized the Visual Studio .NET toolbox from within the Dashboard.
5. Reloaded my project and removed all of the Syncfusion references from within the solution explorer.
6. Started a new form and added a syncfusion control from the toolbox to force re-creation of the syncfusion assembly references.
All of the form designers including those that use the bannertextinfo component now load OK. My guess is that there was an old reference hanging around somewhere that was causing the problem.

Hi Steve,

Thank you for the update.

We are glad to hear that problem has been solved.

This issue seems to appear when we use different framework and assembly reference in Application. Please try the below given steps and let me know if this helps you

1) Open {SyncfusionEssentialStudion Version(eg.} Dashboard.
2) Run the AssemblyManger with 'Removeallversion' option. This will remove all the Syncfusion assemblies from GAC and public assemblies folder.
3) If you found any Syncfusion assemblies in GAC and C:\Program Files\Syncfusion\Essential Studio\{SyncfusionEssentialStudion Version(eg.}\Assemblies\{FrameWork Version}folder. Please remove it manually all the Syncfusion assemblies.
4) Run the AssemblyManager from the Dashboard and install the {only required version} assemblies.
5) If your Target Framework is {Framework Version(eg.4.0)}, then please remove 2.0 and 3.5 Syncfusion assemblies from GAC and Assemblies folder and vice versa.
6) Please ensure that only required framework assemblies are in GAC (c:\windows\assembly) and also in Assemblies folder (C:\Program Files\Syncfusion\Essential Studio\{SyncfusionEssentialStudion Version(eg.} \Assemblies\{2.0 and 3.5})
7) Open the {SyncfusionEssentialStudion Version(eg.} Dashboard.
8) Run the Multi Target Framework targeting to {Framework Version(eg.4.0)}
9) Click OK once operation completed successfully.
( Also please try using Toolbox Configuration in Dashboard to install the Syncfusion Tools in the Visual Studio)

Also please try using below steps in your projects.
10) Remove Bin and Obj folder from Project path
11) Open the Visual studio IDE and open the project
12) Rebuild your project.
13) Please check once again the Syncfusion assemblies are referring {SyncfusionEssentialStudion Version(eg.}
14) Try these and the issue should be resolved.

Thanks for your contribution in Syncfusion CommunityForums.
