Hi Gerhard,

This issue is fixed now in our latest release.
Please download the latest VSIX installer from here:

Visual Studio 2022: Wisej.NET 3 VS 2022
Visual Studio 2019: Wisej.NET 3 VS 2019

This is required for the new templates to be installed.

Hi Ruben,

It looks like WebSocket is disabled in your environment,
You can check its state in Wisej using “Application.IsWebSocket”, in a click event, if you’re doing it in the Main call you’ll always get False!

If it’s indeed disabled, then you’ll have to enable it and check the results!

Hi Ruben,

please provide us with a full compilable test case showing what you try to achieve.

Hi Jesus,

I have attached the same project with the workaround.
The “unexpected tocken” error you got is due to the different quote marks when you copy/paste code from the forum.

Hi Alex,

can you please send your web.config to supportATwisej.com and we´ll take a closer look?

Thanks in advance,

Hi Alaa!

Thanks for your quick reply.

I have inserted the code you have sent me in the program, but when I run it, it returns the following error: Invalid or unexpected token

Any more suggestions?

Hi Andrew,

is the function declared as public static? Please also note the last paragraph in our docs about RemoteMethods

https://docs.wisej.com/docs/concepts/javascript-object-model#remote-methods

If it still fails after using the mechanism described there, please wrap up a small repro case that we can use to inspect that issue.

Thanks in advance.

Best regards

Hi Jesus,

Thank you for reporting this issue.

As a workaround, you can add these few lines of code:
Private Sub DataRepeater1_ItemCloned(sender As Object, e As DataRepeaterItemEventArgs) Handles DataRepeater1.ItemCloned

e.DataRepeaterItem.Eval(“this.removeListener(‘click’, this._onItemClick);this.addListener(‘pointerdown’, this._onItemClick);”)

End Sub

We will notify you when a fix is issued in a future build!

Thanks, Alaa. It works.

Hi Tiziano,,

There’s many many ways of dealing with Pagination, or caching in this case.
Wisej.NET’s DataGridView is already in full virtual scroll mode,

You can go with the legacy route, and that is basically specifying what page to look for.
Or, you can go with the “Caching approach”.

The client-side can manage its own cache and paging whereas the server side can implement any caching system.

I have attached a sample to showcase this behavior!

For more info, you can check out Microsoft’s documentation about implementing VirtualMode from here: Microsoft | Implementing Virtual Mode in the Windows Forms DataGridView Control

In Wisej.NET, to virtualize the server side you’ll need to use VirtualMode and CellValueNeeded and DataRead event to manage the paginated cache.
You can check out our documentation for that here: Wisej.NET Documentation | DataGridView.DataRead

Hi Ruben,

Background tasks are completely separated from the session and the user that started them. They are simply threads running on their own without any knowledge of the session that started them.
This is why you’ll need to update the application to reflect any changes or updates done in a background task.

For this, Wisej has the “Application.Update()” method.
However, in order for it to work correctly, you’ll have to add the method INSIDE the Application.StartTask() method.

Otherwise, when the task is finished doing its thing, it won’t get reflected back to the client.

You can find out more info in our documentation : Wisej Documentation | Updating UI Using Background Tasks

Hi Ruben,

please take a look at this older discussion:

https://wisej.com/support/question/get-the-open-forms

Once you get the form you can call whatever is public there. (call a method to set the value or directly set a property/control value).

Hello Frank,

Here you go. I attached the two projects in a zip file. The code changed since the last upload, since I’m actively testing things.
