  Hello,

  I’m trying to bind a form to an object with a List property. The List property has to be bound to a TrueDB Grid but I get an exception System.ArgumentException: DataMember property ‘XXX’ cannot be found on the DataSource when the XX.design.cs file hits the line that asignes the data source to the control.

  The objects are defined like:
  
  Class A with property List myList

  The binding sources are defined like
  
  bsA.DataSource = typeof(ClassA)
  
  bsB.DataSource = bsA
  
  bsB.DataMember = “myList”

  This was working fine in old versions and I’ve been postponing the upgrade for a long time so see if this issue was fixed, but we need to use some of the new functionality and we have to upgrade. There is a work around that I have commented in the project attached, but it is not a valid solution because the project is very large.

  Please, we need an answer asap.

  The project is in VisualStudio 2017 with .net 4.6.2 and C1TrueDBGrid 4.0.20181.303.

  Thank you.

  Hello,

  It seems the project did not attach properly, this might be because your project exceeded the maximum allowed file size(5 Mb). In that case, please use the following URL for uploading your project: https://www.dropbox.com/request/Dm5zQaQs6SB6txlF0Ntb

  Thanks,

  Hi!

  Apologies for the delay in getting back to you.

  Yes, I am able to see the exception with the latest build at my end too. Since I’m not sure about the last version that you were using. So, can you please tell me last version with which this project was working fine? It might help us in further investigation of this issue.

  Best regards,
  
  Meenakshi

  Hello Carlos,

  Due to “BeginInit” or “EndInit” method of officesBindingSource, designer environment to prevent the control from being used before it is fully initialized. Hence, could you please assigned “Offices” as a DataMember of “officesBindingSource” after assigning “officesBindingSource” as Datasource to the “officesGrid” Grid.

  Hope it resolves your issue.

  Thanks,

  Hello Mohit,

  That is what I’ve been doing, but the problem is that the code is in the designer.cs file and it gets generate every time there is a change in the design of the form. The code gets re-arrange and stops working. The code has to be in the designer file to be able to use it for the formatting of the grid and it cannot be moved to de .cs file.

  This is not a solution, it is a temporary fixed that is not sustainable.

  Thank you.

  Hi Carlos!

  The exception no longer occurs if the same application is run with the latest builds of 2018v3. To check the fix, you can download the builds from here: http://prerelease.componentone.com/dotnet40/c1winforms/2018-t3/C1WinForms.4_4.0.20183.338.zip or update using C1Live utility.

  I understand your frustration regarding the concern but we request you to help us trace the issue so that we can help you at the earliest.
