Create a blank new Wisej-4 project using the provided templates. It will create a sample for you with a couple of clicks. There are also dozens of samples in github.

This is a typical startup.cs with app.UseWisej();

https://github.com/iceteagroup/wisej-examples/blob/4.0/MDIExample/MDIExample/Startup.cs

In your solution there is no main method, the launchsettings doesn’t have true for launching the browser, the start url is wrong,  there is no call to app.Run(), the web.config is setup incorrectly for IIS instead of Kestrel (see comments in the one we provide). It doesn’t work with asp.net core regardless of wisej.net. If you copy the correct startup method it will work. We provide everything you need to make it work correctly.

https://stackify.com/how-to-deploy-asp-net-core-to-iis/  <– this works only when deploying in IIS, doesn’t work with Kestrel. This is all standard asp.net core.

Wisej is a .NET Core middleware, which is typically added using UseWisej() (not AddWisej).

Create a new project using the provided templates and attach a new blank Wisej 4 project (without net48) that runs and opens a simple page with a label and a button. Look at the running project to see the setup, which is all standard net core and asp.net core.

Hi Ivan,

themes are identical but new themes may only be published for 4.x

This only happens EVERY OTHER TIME. Once the error occurs, I click the Stop Button and immediately restart the app and it ALWAYS runs correctly (the second time).

If this is true: “There is no Application, no Configuration and no Session available when initializing statics.” how is it running correctly the second time?

Screen shot of error. This is the exact line of code where the error occurs EVERY OTHER TIME.

Hi Jean,

we need a test case to see your code. What does “crash” mean? Do you get an exception.

Excellent – defined in the themes file! Thanks so much!

Using an ImageList for single buttons is a neat trick 😉

It can be changed globally via the theme:

Locate the button appearance in your theme and modify the iconSize property within its properties section for the default state:
Code

"button": {
"states": {
"default": {
"properties": {
"iconSize": {
"width": 64,
"height": 64
}
}
}
}
}

It can be changed locally (for a single button) using an ImageList
1. Add an ImageList component to your form or component.
2. Set the desired ImageSize property on the ImageList component (e.g., new Size(32, 32)).
3.Assign this ImageList component to the ImageList property of the Button control. The button will then automatically resize any image assigned to its Image property to match the ImageSize defined in the ImageList, even if the image is not explicitly added to the ImageList itself.

See attached sample.

Still facing the same problems. Any other idea? Our solutions are integrated with several independent projects (class libraries, ui projects, etc).

You can simply check the nuget package in the Solution Explorer.
Expand Dependencies, then either net481, net8.0, or net8.0-windows (any of them work). then expand Packages. See screenshot.

OK,

please ignore, found that this issues was fixed in 3.5.18 version

Hi Rene,

my initial answer was wrong or not entirely correct.
Some shortcuts can be overridden with Accelerators.

Please find attached a sample for CTRL+S that seems to be working in Chrome, Firefox, IE and Edge.
But you might test around a bit to see if your shortcut works in your target browsers.

Hi Justice,

we can’t work on this spare information. Please provide more details about your application and setup.
Is it failing inside Visual Studio? On a deployed version (IIS?)? Windows? Linux? etc.

If it’s on a deployed server you might find this useful:

Hi Rene,

short answer: You can’t. It’s up to the browser to handle these shortcuts before they even reach the web application.
So only way is to search for browser setup options.

Best regards
Frank

Make sure that you have included the Wisej2 (or Wisej3) nuget package in your project. Check your .csproj file, there should be a line that looks something like this:

<ItemGroup>
<PackageReference Include="Wisej-3" Version="3.5.*" />
<PackageReference Include="System.Data.SqlClient" Version="4.*" />
</ItemGroup>

You can do this by using accelerators and the ClientClipboard extension.

Make sure to install the ClientClipboard extension using nuget.

To create an accelerator, open the Page in the designer and go the the Page properties. Click on the 3 dots by “Accelerators” and click “Add”. Click on the dropdown arrow and click the box for ctrl and set the key to C. See attached picture.

Once that’s set up, go to the lightning bolt to open the events for the page. Add an “Accelerator” event. It should be called Accelerator_CtrlC

Then paste this code in the accelerator event:

private async void Accelerator_CtrlC(object sender, AcceleratorEventArgs e)
{
if (dataGridView1.CurrentCell != null)
{
var value = dataGridView1.CurrentCell.Value?.ToString();
await ClientClipboard.WriteTextAsync(value);
}
}

I’ve attached a working sample here.

To fix the compiler error, you have to add a reference to System.Runtime.Caching assembly in the project.

1. Right-click your project → Add → Reference…
2. Go to Assemblies → search for System.Runtime.Caching
3. Check it → OK

OR simply add this code to your .csproj file:

<ItemGroup>
<Reference Include="System.Runtime.Caching" />
</ItemGroup>

Hello Julie,

Thanks for your quick answer. When I try to code something like if (System.Runtime.Caching.MemoryCache.Default.Get(mySessionId)==null) the compiler says that Caching doesn’t exist in System.Runtime. The funny thing is that if I test this in the quickWhatch at runtime it words indeed.

The application I’m working with creates some directories on the disc with the sessionId as name for working purposes. I now would like to destroy those directories if the session ID is no longer valid. How can I distiguish invaid ones from the ones still in use ?

TIA

Mirko

You need to put your code in the redraw event of the canvas.

When you call the drawing actions on a canvas control they are executed on the browser but not persisted. In Redraw you have to update the control and draw what is persisted.

Your code should look like this:

private void canvas1_Redraw(object sender, EventArgs e)
{
MakeBoard((Canvas)sender);
//insert code here that draws the png images
}
