Dropdownbox clear selection

[Former Member]

Hi,

I am using a dropdown box by key to allow the user to select an entry.

This dropdown box will be filled by a source which can change.

Situation:

The DDbox has been filled and the 1st entry on top is blank.

The user now selects a value from the DDBox and the selected field becomes visible as the 1st entry.

Problem:

When the DDbox will be filled with new values the old selceted field is still visble as the 1st entry.

question:

How can we set it to empty again as at the start?

Thank you!

regards

Paul

The DDLBByKey gets is selected value from the context Attribute the key property is bound to. If you want to reset the selection of the DDLB just update the context attribute and set it back to blank.
