I downloaded the latest 6.4 Preview pack and has several problems/Issues. All these used to work in the previous version.

(In the Version of the DLL, it says 3.0.5701.0.)

1)

DateTimePicker has now alwayes the ShowCheckBox as true, even when I in the designer set this to False. After a compile, save and run, they are back to true and they are also displaed on the form with the box on. I have fixed it with on the load of the form, setting the ShowCheckBox = False)

2)

Click on a button, draws a dotted line around the control, which is bigger than the button itself. Looks strange

3)

I have a grid, I set up databinding (datagridView1.DataSource = bindingSource1) that works. then when the user chooses a row, a modal box is shown with some more data. that works also fine. (The background is now darked out), but when I close the modal form. I then refreshes the grid and in that sub, I get an exception on the

DGPC.DataSource = bindingSource1

Nullreferenceexception was unhandled by user code. use the new keywrd to create an instance of an object

and both the DGPC and the BindingsSource1 exists and has values.

it comes when I return from the modal form. Seems like it has losts some memory and previous values.

I really hope that you can help me out. I can live with the 2 first issues, but the 3rd one, has destroyed the application and I will have to go back to the previous version.

Kind regards

Hi Jan,

First I think you should realize that the 6.4P1 is a preview release, not meant for developing serious applications, but to show the community what is coming in the next release. We knew up front that it would be unstable in some areas and some parts of it even not functioning. See more about this in this thread here.

And now to your reported problems:

1) See this issue here.

2) This is one of the reported problems in this issue here. We are aware of that this is also a problem in 6.4P1

3)  Regarding this problem, we know that DataGridView is very unstable in 6.4P1, but if you do have an application in 6.4P1 that demonstrates this problem, then the best way to describe those problems is by creating a most minimal application that demonstrates the problem(s) and then send your application to support [at] visualwebgui [dot] com with a link to this forum thread, along with some description about how to reproduce the problem.

Please also clean the solution before compressing it and reply to this post after sending, so we will know to check for your support request.

If connection to database is needed, please make sure you will either be using all memory based data or the MSSQL Northwind sample database for your connection(s)

Hi Jan and thanks,

Yes is would be very helpful if you can create a simple app that reproduces the problem. Just remember that if you need database connection run your app, then make sure it's connecting to the Northwind MSSQL sample database so we are able to test.

One thought though... You say you get an error at "DGPC.DataSource = bindingSource1" after you close the modal detail form. Does this mean that you reassign the datasource each time you close the defail form?

If you need the Grid to be updated afterwards, you could either use DGPC.Update() or you could use bindingSource1.ResetBinding(false) to force it to update, if it doesn't.
