Diagram Node Label Edit Fails - Textbox Loses Focus on Each Character Typed When Windows Text Suggestions Are Enabled

[Rafed Wassila]

Hello, 

I am encountering an issue editing blazor diagram component node name. When attemping to rename a node the textbox loses focus and OnTextChanged event is fired on each character typed which prevent completing the edit. 

This occurs only when windows  "Show text suggestions when typing on the physical keyboard" setting  is enabled as shown in the image below : 

This issue can be reproduced on this example: https://blazor.syncfusion.com/demos/diagram/flowchart?theme=fluent2.

Best regards.

Hi Rafed Wassila,

 

We have fixed the reported issue  “Node Textbox Loses Focus During Annotation Addition in Blazor Diagram When Windows Text Suggestions Are Enabled” and included the fix in our SB patch release(30.2.4). Please update the “Syncfusion.Blazor.Diagram” package to the latest version in your application to resolve the reported issue. Please find the package link below.

 

https://www.nuget.org/packages/Syncfusion.Blazor.Diagram

Root Cause:

The issue stemmed from a previously implemented behavior where the annotation box was closed at the script level during the mouse leave event. As a result, when the Windows Text Suggestions triggered a mouse leave event, it inadvertently caused a loss of focus, leading to unexpected behavior in the UI.
