IJSEditDialogControl.ValidateInput Method
|
LMD DialogPack
|
|
|
Called so the control can prevent a dialog from closing.
function ValidateInput(out Message: TJSString; const ModalResult: TModalResult): Boolean;
Implement the CanClose method to provide validation on the control. If the method returns false then an appropriate error message should be returned in the Message parameter. The ModalResult parameter indicates what the result value of the dialog will be so you can perform any required validation that might prevent the dialog from being closed. If the user has cancelled the dialog, then there is no point in validating the dialogs contents.
