I'm creating the shapes, connections programmatically based on my custom configuration file.

I'd like to change the Text color of RadDiagramConnection based on its value, like: OK-> Black; NG-> Red

See below screenshot,

Could you show me how to do it? Thanks!

Hello Aeroth,

One way of dynamically changing the color of the RadDiagramConnection content is by checking if the content value matches a certain requirement and that is done by changing the Foreground property. I am attaching a code snippet for your convenience:

 

this.diagramConnection.Foreground = Brushes.Red;

 

As well as the snippet I am attaching an example project for a possible solution to your question.

Hi Stenly, thanks for the solution. Is there an event like ConnectionTextEditCompleted? So that I could change the color instantly.

Hello Aeroth,

You could look at EndEdit event which fires when you finish editing an item.

The following code snippet shows where to put the event into the RadDiagramConnection control:

<telerik:RadDiagramConnection  EndEdit="radDiagramConnectionLine_EndEdit"

I am attaching an example project to show the logic behind the event.
