Hi Simone,

BackColor not working in NavigationBar is fixed in the extension, updated in GitHub.
The crash you have noticed is logged as #1773 and fixed now.
The fix will be included in the next Wisej build.

Thanks,
Frank

Update: I found it. It depends on

/* Fix Chrome rendering failure with transition animations. */
div {
-webkit-transform: translateZ(0);
}

in wisej.css

if i switch this style off in console from div, map is rendered correctly, but i failed override it in code.

Hi,

thank you for fast answer. problem is with map controls, they are hidden somewhere. its on local machine, my result is same as yours. Config is ok, no errors at console.

map controls  are rendered in dom, problem is probably somewhere in conflicting css

leaflet.ok.png is similar sample but in plain html https://leafletjs.com/examples/quick-start/example-basic.html

leaflet.in.designer.png shows control as rendered in form designer

thank you

pavel

Hi Guys,

Still struggling with Crystal Reports.

I am using VS2017 and Crystal Reports 13.0.24 (latest version)

I have no problem with creating reports and applying data to them etc. The issue is with the Crystal Reports Viewer – whatever I try I am unable to attach (or indeed reference) the crviewer. I know everything is installed correctly as I can open a new VS project and as I would expect the crviewer is available in the toolbox.

Unless I can attach the Crystal Reports viewer to a form then there is no way to display the report

Any help would be appreciated

Hi Andrew,

basically there is no way way of knowing or relying on the index on the client.
If you create multiple instances of the same form class and then need to reference
it on the client in JavaScript you can either

a) give each instance a different name (the Name property) or
b) use “this” to refer to your instance when calling a script on the server

To check if a reference is an array in JavaScript either use Array,isArray() or test the length property !== undefined.

Hope that helps.

Best regards

Thank you Jens – you steered me in the right direction.  Here is the line of code that ended up working for me in case anyone else needs it:

htmlChat.Eval(“this.scrollByY(1000)”);

When your code “awaits” a response from another web server (or another web service, or another thread) it cannot automatically update your client because there is no pending request from the browser and it’s impossible to update the browser without a request from the browser. Unless you push the update using a websocket connection. In Wisej it’s built in so you can call Application.Update() after the await. Unless the await is waiting for a Wisej response (an async dialog or messagebox or javascript call), in which case the update is automatic.

The way async/await works in .NET compilers is to extract the code after the await and compile it into a callback method. The await statement receives a Task instance from the async method, then returns and completes the execution before the await. When the task is completed it calls the callback from the thread that completed the execute in the await. It’s identical to calling a function passing in a callback method.

In alternative you can wait on the task returned by the async method. All async methods return a task:

await Test(); // asyncronous in Wisej

Test().Wait(); // waits for the task to complete, like in ASP.NET

Async programming on a desktop app is easy since you don’t need a request to update the desktop.

Async programming in an ASP.NET app is emulated and in reality it blocks the request. If you try an async event with ASP.NET/MVC or WebAPI you will see that the browser waits for the request to complete synchronously and the ASP.NET session is locked. In fact the calling thread waits on the task.

In Wisej is truly asynchronous. The event is fired and executed on the server asynchronously.

Hi Shawn,

when you debug your code, can you please check the value of QueryString ?
Also did you try as ?PaintJobs without the slash before ?
