Kanban: Toggle column fails with Async initialization


I'm using Blazor Webassembly with .Net6 (6.0.10) and Syncfusion

It seems that the toggle column doesn’t work when OnInitializedAsync is used. If I toggle a column, its title is toggled but not its content.

I attached an example and a print screen.

Do you accept it as an issue?

The problem can be avoided if the Kanban is displayed after initialization is complete. See “_initDone” boolean in my example.

Best regards,

Hi François,

We have validated the reported issue from our end and found that the reported issue occurs due to the delay added in the OnInitializedAsync function. During that delay, the Kanban scripts are not properly rendered and hence the issue occurred. 

So we suggest you to initiate the Kanban columns once the Kanban board is fully rendered like the way you have tried using a Boolean variable to resolve the issue.
