Hi @111,

I do not understand what you are trying to do.

when I clicked '>>' button

I want to move the selected value on the left to the right.

but I don't know how to access the selected value in c# code

plz help
thanks

You use a property which contains the value. That property is usually specified via @bind-Value.

thanks to you ~
have a nice day~
