IbComposer_getAllAmpersValues([verifySelection]);

where:

verifySelection

Boolean

Is an optional parameter. When true and when the Selection required property for the control is set to Yes, this returns an empty string for the parameter controls that do not have a selection made.

Note: All controls have the Selection required property. This property is set to Yes by default. If a control has no valid selection made at runtime, a red box appears around it and the following status bar message displays:

Please make required selections

function button1_onclick(event) {
   var val = IbComposer_getAllAmpersValues();
   alert(val);
   OnExecute(event);
}
