Refreshes the current record (the current data refresh caused by a control modification of the screen)

Recently encountered a problem, need a control modified, assign a value to several other fields,

But there is a problem, or you have to leave the control after the cursor, the other field values will change;

Either the entire picture is reloaded, and the data cursor is re-selected on the first data.

For the above issues, I reviewed the code for the purchase order header status update after the system purchase order is posted to the warehouse.

Code in the Purchformletter \ Mainonserver method, there are the following methods,

Purchformletter::updatecallerdatasource (Purchtable_ds, recordexists, doexecutequery);

After entering, the contents are as follows:

if (recordexists)    {        if  (doexecutequery)        {            purchtable_ds.executequery ();        }         Else         {            purchtable_ds.reread ();            Purchtable_ds.refresh ();            Purchtable_ds.editpurch ();            Purchtable_ds.rereadlines ();        }    }     Else     {        purchtable_ds.research ();    }

As in the code, when the data exists, either just requery the data or perform a refresh of the current record.

Yes, it is.

Purchtable_ds.reread ();p Urchtable_ds.refresh ();

These two lines of code play a role in refreshing the current record.
