RE: Exact scenario to use reread, research and refresh

Hi Chaiatanya,

Actually as business need i added one button "Update" in Carate customization form in header. The function of this button is when user clicked button "Update" it will check all corresponding records in Line Table based on Carate Ids and update checkbox "Bypass Carate" to YES.

It's worked fine but user will see check box "Carate = Yes when press F5.

I want this without press F5.

shall i go for only table_ds.refresh() ?

Please give me more shed on this.

Hi,

Based on your business need we need to make a call to this form datasource methods.

research(): research() method will rerun the existing form query against the database, fetches the data and also honours the filters that are set on the grid. Like if we want to have some operation to be performed on the selected list, right after the operation the selected list is maintained without removing it.

refresh() : Refresh will read the data in the data source cache and no interaction with the data base happens to fetch the new/updated record values

reread(): reread interacts with the data base and runs the query against the data base in order to fetch the new/updated record values. But will not show the updated values in the form until calling the refresh method. So general usage is

formDataSource.reread()

formDataSource.refresh()

Hope this information helps you.
