Set a text property of TpsLabel

granale

Hello,

 

I want set the text property of a TpsLabel component. It works on virtual controler very well, but on real controler not. I use RW5.13.0225. See following lines.

 

_Test.SetValue("3", true);
this.lMode.Text = "Grundstellungsfahrt";
_Test.SetValue("31", true);

In real controler the variable _Test is 3. I get also no exception.

Please, help.

The variable must be declare in the controler as PERS.

...yes I know. That is not the problem. My problem is, the 3rd line in my example is never called. But only on real controller!!!!

Hi,

 

Is this code running in the UI thread?

granale

...no, it isn't. Is in a subform. But the controller is in UI-Thread. Also the Variable-Object for the change event.

The UI can be modified only by code running on a UI thread. Even if the controller was created in the UI thread, all its events are executed in a non-ui thread. If you would want to make a change in the UI, make sure to invoke the UI thread ...

 

Sample Pseudo-code ..

 

 

// Assumming this code runs inside a TpsForm

 

void MyNoUIThread (....)

{

    this.Invoke(new EventHandler(this.MyUIThread ), this, EventArgs.Empty));

}

 

void MyUIThread (....)

{

   // Change of the UI

}
