Event when changing the content of a label?

[Walter Porada]

Hi there

Is there a way to get notified, when the text of a Label is changed by the user?

I´ve got a Group node, consisting of a rectangle with a fixed Label (not editable), an Image node and a Label node, which should be edited by the user.

I expected to get the "Property Changing"/"Property Changed" from the eventsink, but actually no event is being thrown.

Is there any way to get notified programatically when the user changed the text of an editable Label?

Using: VS2013/.NET 4.51/Winform/VB.NET/Release 13.1.0.21

with best regards,

Walter

Hi Walter,

Thanks for using Syncfusion product.

We are unable to reproduce the reported behavior at our end. Please refer the below code snippet, video and sample for your reference.

Here is the code snippet:

[C#]

private void Form1_Load(object sender, EventArgs e)

{

Ellipse ellip = new Ellipse(100, 100, 100, 70);

ellip.Labels.Add(new Syncfusion.Windows.Forms.Diagram.Label(ellip, "Test"));

diagram1.Model.AppendChild(ellip);

//Property changed event to get Label Text changing event

diagram1.Model.EventSink.PropertyChanging += EventSink_PropertyChanging;

//Property changed event to get Label Text changed event

diagram1.Model.EventSink.PropertyChanged += EventSink_PropertyChanged;

}

void EventSink_PropertyChanging(Syncfusion.Windows.Forms.Diagram.PropertyChangingEventArgs evtArgs)

{

if (evtArgs.PropertyName == ".Text")

{

//Define the Logic

MessageBox.Show("Label Changing");

}

}

void EventSink_PropertyChanged(Syncfusion.Windows.Forms.Diagram.PropertyChangedEventArgs evtArgs)

{

if (evtArgs.PropertyName == ".Text")

{

//Define the Logic

MessageBox.Show("Label Changed");

}

}

Hi Naganathan

Allright. Now I see my mistake. I was subscribing to the Diagrams EventSink, not to the Models one.

Thank you for your assistance.
