[CLOSED] Resetting a Form on the client
Hi,
Please consider the code sample below. I'm curious what other call is required to select the initial value of a ComboBox on the server so that it doesn't get reset to empty on the client. I'm selecting an option on the server thinking that it's persisted into the form values. However, the Reset button cancels it out.
