https://answers.axonivy.com/questions/443/how-to-set-the-mandatory-property-dynamically<p>I need to set the <code>mandatory</code> property of some widgets at the run-time depending on some run time criteria and without having a typed reference to the widget. How can I do this?</p> <p>I can do this for example for the <code>visible</code> property. I can loop through all components of a display or other panel or container by <code>panel.myContainer.getComponents()</code>, select which components I am interested in and then call <code>setVisible(Boolean)</code> on them.</p> <p>I cannot call <code>setMandatory(Boolean)</code> on this level but I would need to. </p>enThu, 29 Mar 2012 05:13:46 -0400https://answers.axonivy.com/questions/443/how-to-set-the-mandatory-property-dynamically/444<p>The problem is that <code>panel.getComponents()</code> returns a list of ULC components. The validation with the <code>mandatory</code> property is an improvement from ivyTeam which is not accessible on ULC level.</p> <p>The solution would be to cast the ULC component to concrete type of widgets and then call <code>setMandatory(Boolean)</code> on the casted object.</p> <pre><code>for(Object object : panel.GridBagLayoutPane.getComponents()) { if(object instanceof RTextField) { (object as RTextField).setMandatory(true); } } </code></pre>Philipp HaslingerThu, 29 Mar 2012 05:13:46 -0400https://answers.axonivy.com/questions/443/how-to-set-the-mandatory-property-dynamically/444
