Two-way binding automatically gets the display labels in the resource file

Demo

When the Dispaly components turn on bidirectional binding, the Display/DisplayName label value is automatically obtained based on the Model property value of the binding and appears as a pre-Label, with DisplayText properties you can customize the display of the pre-label, or by turning off the display of the pre-label through the ShowLabel property

Custom labels

Set the DisplayText value to custom label

Occupants

The value of DisplayText is displayed when ShowLabel is true, regardless of whether the value is set

Zhangsan 1000
Do not occupy seats

The value of DisplayText is not displayed when the ShowLabel is false

Set the Lookup value to IEnumerable<SelectedItem> collection, through which the component will perform translations through the Value display Text

Demo

In this example, the component Value='@IntValue' set Lookup='@IntValueSource' component to display the Text corresponding to the value of the Value
InitValue: 1,2,3
IntValueSource: Text1,Text2,Text3

Oh snap! Failed to reconnect with the server. This is typically caused by a longer network outage, or if the server has been taken down. You can try to reconnect, but if that does not work, you need to reload the page.
Oh man! The server rejected the attempt to reconnect. The only option now is to reload the page, but be prepared that it won't work, since this is typically caused by a failure on the server.
