Are you trying to show data from database in a data grid and on select of one record, try to show the details of the selected record?

IF yes, then you dont need two data grid. You need one datagrid and one data view.

The data view data source must be set to Listen to widget and select your master datagrid. Within Data view, you can actually any data of the selected record.

It is very difficult to understand your question, in the way it is written now.


Thank you for reply.


This is what i want. almost my customer want to see more information on one page.

some time need more grid info only one page. 3 or 4


and my second question.


Among the numerous data, I want to display only the data I want on the grid

For example, a list of Koreans among Amazon employees


when i used datasouce microflow. only apply when load page.

but i want chage key-word for search. and refresh.


what can i do.


As far as I know, if you do the following, it will be searched among the data once called.

“use filter text”

However, new information entered elsewhere must also be inquired immediately. at the time ‘refresh’ button click event.
