InvalidInputDetect (Function) In french: SaisieInvalideDétecte Detects and signals an error on required controls left empty and/or controls with invalid data.
IF InvalidInputDetect() THEN
RETURN False
ELSE
RETURN True
END
Syntax
<Result> = InvalidInputDetect([<Element used>])
<Result>: Boolean - True if at least one required control is left empty or contains invalid data,
- False otherwise.
<Element used>: Optional control name or window name Name of the control or window to be checked. If the control is a container (Tab control, Supercontrol, etc.), all its controls will be checked.
If this parameter is not specified, all the controls in the current window will be checked. Remarks Characteristics of the verification/detection of controls that require data input/contain invalid data The input will be checked in the following types of controls: - Radio Button control/ switch: if the mandatory input option has been activated (or property MandatoryInput to True), check that at least one option is selected.
- Grading field: if the mandatory input option has been activated (or property MandatoryInput to True), checks that a grade has been allocated.
- Combo input if the mandatory input option has been activated (or Property MandatoryInput at True), verifies that a value has been entered or selected in the combo.
If an input mask has been used, the function checks that the entered data matches this mask.
If a custom mask with an InputMask variable is used, the verification is performed by executing the procedure associated with the CheckIfValidInput property of this mask. - Combo without input If the mandatory input option has been activated (or Property MandatoryInput to True), verifies that a value has been selected in the combo.
- Edit control field if the mandatory input option has been activated (or Property MandatoryInput to True), verifies that a value has been entered or selected in the Edit control.
If an input mask has been used, the function checks that the entered data matches this mask. If a custom mask with an InputMask variable is used, the verification is performed by executing the procedure associated with the CheckIfValidInput property of this mask.
Only active and visible controls are checked. Miscellaneous - The function sets focus to the first control detected according to the tab order.
- You can customize the error display mode in the description window of the relevant controls.
- The control will no longer be considered as containing errors once the data is edited by the user or programmatically.
- To know which controls are required/contain invalid data without highlighting them, use InvalidInputListControl.
- The MandatoryInputMessage and InvalidInputMessage properties are used to customize the error messages displayed in case of invalid/required input.
- Special case: Edit control or combo box with custom mask via a InputMask type variable. If the control does not have focus when InvalidInputDetect is called, the text displayed in the control will first be formatted with the FormatOnEntry property of the mask before checking its validity.
