Inputfield: Returning from value help: Triggering roundtrip?

[Former Member]

Hello Experts

I'm looking for a way that WD runtime triggers automatically a roundtrip when data in the inputfield has changed (for instance returning from a assigned value help change the value of the corresponding input field). Can WD4A detect such change without pressing ENTER or TAB and triggering a round trip to the server?

Regards and thanks for your help.

well, if it's an input field with a search help and a limited number of options, you could try using a dropdown

there's an roundtrip when you change the selection

but it depends on your requirements ofc...

Hi,

As per my understanding, there is no automatic process of triggering when a change occurs in

input field.

Please try to do this way - Using the Context change log for that attribute can be used,

IF_WD_CONTEXT ->ADD_CONTEXT_ATTRIBUTE_CHANGE for Adds an Entry for Attribute Changes

Enable this context change log for this context attribute to which the Input field value is bound.

And when ever the change occurs then call the appropraite method.

By defalut, F4 selection for the Input field doesnot trigger any event. You need press Enter Key or Tab or any other event that gets triggered fror input field.

Hope this helps you.

Regards,

Lekha.
