| Summary | 0005190: jvDBlookup don't refresh displayValue when lookupindex is the same value of the previous | ||||
| Description | Suppose you browse a table1 that is master for a table2. Table2 is master for table3. You have a jvDBlookup with use table1 as datasource and a field from table1 as datafield. The same jvDBlookup use Table3 as lookupsource + a field as lookupindex and another field as lookupdisplay. When you browse the table1 this change also table2 and table3 but if the value for the field lookupindex and datafield is the same as the previous, the lookupdisplay don't change ! I've tryed to force the display in the following way (on an event of record change of the first table) but none of this worked : // DBLCindc.Refresh; // DBLCindc.Realign; // DBLCindc.Repaint; // DBLCindc.Update; // DBLCindc.ResetField; // DBLCindc.DisplayValue:=IFAT.Tindc.fieldbyname('indirizzo').asstring; P.S: DBLCindc is the TjvDBlookup Solved with the following new method in the class and calling (DBLCindc.ForceDisplay;) in the event record change Below the patch with the current SVN. If you find a way to automate the display change without calling "ForceDisplay" is welcome ;-) | ||||
