Example of cascading combobox

[satyajit-behera]

Hi, is there any example of cascading combobox.
Ex - If I select country, based on that, states should be filled.
Thanks in advance.

See #1298 for example code with Select. Same idea

Nope. For search you'd need to use the autocomplete

Thanks

while using autocomplete, is it possible to get the underlying Pk value of the selected items. ValueChanged="HandleCountryChanged" gives only the typed value in corresponding method param.

I would advise to use @bind-SelectedItems and then add a @bind-SelectedItems:after method to work with the variable you used to store the selected items in. You can get to all the item data that way. You shouldn't have to tie in to the binding process like you are trying to do.

See https://www.fluentui-blazor.net/Autocomplete#default for an example. We just get the country name and display it, but you could get all Country properties like that

Thanks a lot. Its awesome. When an item is removed from the list, it does not fire the method for @bind-SelectedItems:after . can you pls guide on that.

If you use the cross on the items' presentation in the autocomplete, it will be removed from the selection. You can see in the example I linked to that the display of selected countries gets updated. I don't think there is a way to trigger the :after callback like that
