Const.PM_DataItemValidate
The Const.PM_DataItemValidate message is sent to a data item when it needs to be validated.
Name | Description |
---|---|
wParam | Unused |
lParam | Unused |
Application should return Sys.VALIDATE_Ok if processing this message and validation was successfully performed. If the validation fails (e.g. the value is not valid), Sys.VALIDATE_Cancel should be returned.
The framework is capable of performing many types of validation automatically. Applications need only catch the Const.PM_DataItemValidate to perform additional validation. The framework will perform the following validations automatically:
Note: Validation method specified in Foundation1 properties
is called after the Const.PM_DataItemValidate message is sent, and then only if
Const.PM_DataItemValidate
returns Sys.VALIDATE_Ok
.
This example catches the Const.PM_DataItemValidate message to check a customers credit before allowing that customer to place an order.
Sal code:
On PM_DataItemValidate If DbPLSQLBlock( c_hSql, '&AO.Demo_Customer_API.Check_Credit( :i_hWndFrame.frmDemoOrderOnTab.dfsCompanyId, :i_hWndFrame.frmDemoOrderOnTab.dfsCustomerId )' ) Return VALIDATE_Ok Else Return VALIDATE_Cancel
C# version:
private void dfsBranchId_MessageActions(ref SalMessage message) { switch (message.Code) { case Ifs.Fnd.ApplicationForms.Const.PM_DataItemValidate: dfsBranchId_OnPM_DataItemValidate(ref message); break; default: break; } } private void dfsBranchId_OnPM_DataItemValidate(ref SalMessage message) { message.Handled = true; if (DbPLSQLBlock(cSessionManager.c_hSql, @":i_hWndFrame.frmInventoryDetails.dfsCountryId := &AO.Trn_Branch_API.Get_Country_Id( :i_hWndFrame.frmInventoryDetails.dfsCompanyId IN, :i_hWndFrame.frmInventoryDetails.dfsBranchId IN)")) { message.Return = Sys.VALIDATE_Ok; } else { message.Return = Sys.VALIDATE_Cancel; } }
