It’s working as expected, not a bug.

When a datagridview is data bound the rows are all virtual. They get created and destroyed all the times allowing the grid to handle unlimited number of rows. There is no instance of a cell that can be used like that.

The real rows must be created.

One way is to use datagrid1.Fill(data) instead of DataSource = data.
Another way is to iterate the rows and force the creation of the real rows:

 Private Sub DataGridView1_DataBindingComplete(sender As Object, e As DataGridViewBindingCompleteEventArgs) Handles DataGridView1.DataBindingComplete

     For i As Integer = 0 To DataGridView1.RowCount - 1
         Dim r = DataGridView1.Rows(i)
     Next

 End Sub

In any case, the control should be created only in Clone() not in New().

The best approach is not to use a child control. It uses a lot of memory for large data sets. Datagrids should not be used like the datarepeater. It’s better to format the cell content using html to display buttons or icons or anything else and detect the click using the Role property of the click event. In html just add role=’delete’, role=’add’ and when clicking on the html in a cell the click event will carry the role string.

Hi Nicky,

You can use the appSettings.json approach like you mentioned above, however if you’re running into issues with running queries on the DBContext, then it could be an issue of how you’re injecting the service into the Service Container.

I recommend heading to our documentation about Dependency Injection.

Can you wrap a small runnable sample that would showcase the issue?

Hi Frank,

I have attached an example developed with Wisej 3.5

Ciao Gabriele,

It’s probably a permissions issue. Check out these AndroidManifest permissions:
https://developer.android.com/training/data-storage/manage-all-files
https://developer.android.com/reference/android/Manifest.permission#READ_EXTERNAL_STORAGE
https://developer.android.com/reference/android/Manifest.permission#WRITE_EXTERNAL_STORAGE
https://developer.android.com/reference/android/Manifest.permission#MANAGE_EXTERNAL_STORAGE

I believe there are other ways to access the files in that directory, but would be more difficult to implement.

Best,
Levie

Hi Gabriele,

apologies for this late answer but I had to research a bit.
Here is the status:

• ViewBuilder extensions was removed from our build files because we planned to add it to “base” Wisej.NET but a bit later this had to be shifted to later.
• Latest source code for the extension (3.5.14) is available here.
• It will be added back to our nuget package deployment starting with 3.5.18

Sorry for any confusion.

Best regards
Frank

For the overall control, you can use a TableLayoutPanel. You would need to have some merged columns (ie colspan=2) in order to get the layout right.

For the blue grids (see attached pictures), you could use a single row datagridview inside of the tablelayoutpanel.

If you require further assistance or want us to produce a sample for you, you can purchase a consulting package at https://wisej.com/services-packages/

You’ll just need to look at how it’s implemented in the sample. There is no separate extension or nuget package for SAP 3D Viewer.

Hi Angelo,

please provide us with a compilable test case that includes the binding that does not work for you
and we can investigate further.

Hello Julie,

thank you very much for the quick reply. I have looked at your code, my scenario is slightly different, but I have found the error.

• I’m using vb.net
• and Wisej WebPage not WebDesktop

But that shouldn’t be relevant. I opened the Page1.vb[Design] designer view -> Properties -> MenuBar ->MenuItems(Collection) ->spacer and set Enabled to False. Thought that was it.

With the help of your code I regocnized that at the file Page1.Designer.vb the line

Me.spacer.Enabled = False

is missing. Add this and the problem is solved.

But now it becomes strange. Opening the Page1.vb[Design] designer view  again, navigating to spacer -> Enabled = True. Leaving the dialog on OK or on Cancel

Me.spacer.Enabled = False

is missing again at  Page1.Designer.vb.

For now, I will pay careful attention on Page1.Designer.vb and the problem is solved for me.

See here: https://docs.wisej.com/docs/getting-started-1/license-activation#server-license

Try deleting the .lic file and regenerating it and see if that solves your issue.

Just for reference, this link may be helpful as well: https://docs.wisej.com/deployment/troubleshooting/license-activation

I’m not sure how yours is set up, but when I try to reproduce, the spacer does not change back color on hover. See my sample.

Hello Jean,

You don’t need to use an HtmlPanel, you can use your own PDF.js inside with the PDF Viewer control, please refer to this older post for more information and a sample!

Also, you can use AI in our documentation website to get a better understanding on how to implement your own custom PDF viewer, you can visit https://docs.wisej.com/api?q=custom+pdf+viewer&ask=true to get a head start!

Best Regards,
Alaa

Glad you’re enjoying the HtmlPanel!

Hi Dino,

We tried with a sample on our end and we couldn’t reproduce.

Can you please wrap up a small runnable sample for us to check?
