Cannot confirm the DropDownList value with a predefined dialog

[Julien Barach]

Hi,

I have a DropDownList and I want the user to confirm before changing de selected value.

Please see the repro link here : https://blazorplayground.syncfusion.com/hXLzZrjHTlXAxeel

1. Select a value
2. Change the value (confirm the dialog)
3. The selected value does not change + clicking on the dropdown directly triggers the dialog so it's broken

If I disable the dialog everything is working fine.

Looks like it's bugged when combined with a predefined dialog.

Regards.

It doesn't work properly.

Something weird is happening with the binded value.

If you select 5, then you select 3 and click Cancel on the dialog, it looks like it's working (but it seems the value is incorrect if you check the Console.WriteLine of my sample).

Then you try to select again the same value (3), here the dialog won't appear and 3 will be the new value.

Hi Julien Barach,

We have included the fix for the issue "“When changing the dropdown value with a confirmation dialog, the @bind-Value returns incorrect data" with our package version “24.2.9”. Therefore, we recommend upgrading to our latest version to resolve the current issue.

Root cause:

• When the ItemData value is updated, the value select event is also canceled.
