Form Designer not working after update after update to 12.2 winform dll

created 12 years ago

I am working in windows application and complete the application in winform dll 12.1 version. After doing all coding i had change to 12…2 version.
Now there is some more logic i need to add and which requires change on designer side (i.e. change of lable text) which is directly affect the designer file of win form application.

When I try to do any change and then open the Designer layout it gives me error. which is trying to change all the designer code by itself. I am not able to do any single chage on designer side using form layout.

Attached is a file for more help.

Please note I have inherit all the require controls (i.e. textEdit, RepositoryItemText, radio button etc) from the user control which is actully inherit from the Devexpress controls itself. So i think it should not be the case which cause any problem. And if it is then it is a bug on new dll.

CAn you please specify work around to solve this error??

      Hi,
      I am really disappointed to hear that our service does not satisfy you. Our Support Team's priority is to help our customers to familiarize themselves with our components to create powerful applications. We always try to recreate the issue and suggest useful hints before asking for a sample project. I understand that if you are asked for a project, it might create the impression that we did nothing to understand the issue or recreate it. This is not the case. For instance, if we do not have sufficient instructions to reproduce the shortcoming or the current scenario is not quite clear, we have to request a project. In most cases, a test sample allows us to reproduce the issue and as a result, to find the issue's cause and answer you more quickly. I believe that in all the cases you faced, our support engineers did their best to provide you with a solution based upon the information you gave. If they requested a test project, it means that they tried different ways to reproduce the shortcomings but failed. Our assistance relies upon the cooperation of our customers. We are always ready to help you, but sometimes we do need additional information. I hope that you understand my point.
      As for the current problem - I have created a test sample. In this sample, I created an XtraUserControl and placed a GridControl onto it. Then, I put this XtraUserControl onto a form and rebuilt the application. If I close and reopen the form designer file, the form is shown properly. I have attached this sample here to demonstrate this.
      So, it is not quite clear what you mean by "DeveXpreess control". I presumed that it was the XtraUserControl. If not, please update my sample to illustrate the issue.
      In the meantime, please execute the following steps:

      1. Check whether or not your application references only version 12.2. If you are using class libraries built from our components in the application, ensure that these assemblies are built with version 12.2.
      2. Close your application.
      3. Clear the "bin" and "obj" folders of your application.
      4. Convert your project to version 12.2 by using our Project Converter.
      5. Open the application.
      6. Clear your solution by using the Solution Explorer. To do this, right click the solution and choose the "Clean Solution" item.
      7. Rebuild the application. To do this, press ALT+CTRL+B.
        Do these steps produce the correct results?
        I look forward to your response.

          Hi Amit,
          I have attached a project illustrating Plato's approach from the Devexpress don´t support Visual Inheritance ticket and it operates properly. Do you use Visual Inheritance in your project? If so, please review the How to enable visual inheritance for Developer Express controls KB article. It may be useful to you.
          If it is not the case, I kindly ask you to provide us with a small project illustrating the issue. This will allow us to determine the cause of the issue faster.
          I am looking forward to your response.
