You can use Attributes to add onclick client side callback. I didn’t know you can do this on span tags, but if it works you can add ‘onclick’ by lblMyLabel.Attributes.Add(“onclick”, “foo();”); But foo(); would need to be a client side javascript function. System.Web.UI.WebControls.Label does NOT have OnClick server event. You could look into using AJAX … Read more
It looks like injector.get(NgControl) is throwing a deprecation warning, so I wanted to chime in with another solution: constructor(public ngControl: NgControl) { ngControl.valueAccessor = this; } The trick is to also remove NG_VALUE_ACCESSOR from the providers array otherwise you get a circular dependency. More information about this is in this talk by Kara Erickson of … Read more
Credit to Steven for this answer, but I had to make some changes for it to work as this.Validators.Where() had some problems. using System.Linq; List<IValidator> errored = this.Validators.Cast<IValidator>().Where(v => !v.IsValid).ToList();

You can confirm this with reflector: public void Hide() { this.Visible = false; } You might use Show() or Hide() when you know the value and use Visible when you take the visibility in as … Read more

I took Jordan’s example and made some changes to it. This version should work for any number of tabs: namespace WpfApplication1.Converters { public class TabSizeConverter : IMultiValueConverter { public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { TabControl tabControl = values[0] as TabControl; double width = tabControl.ActualWidth / tabControl.Items.Count; //Subtract 1, otherwise we … Read more
Button controls have a PerformClick() method that you can call. button1.PerformClick();
OrbitControls source Zoom in / zoom out this.minDistance = 0; this.maxDistance = Infinity; Where to stop rotation : this.minPolarAngle = 0; // radians this.maxPolarAngle = Math.PI; // radians Don’t let to go below the ground controls.maxPolarAngle = Math.PI/2;
You can get access of the NgControl through DI. NgControl has all the information about validation status. To retrieve NgControl you should not provide your component through NG_VALUE_ACCESSOR instead you should set the accessor in the constructor. @Component({ selector: ‘custom-form-comp’, templateUrl: ‘..’, styleUrls: … }) export class CustomComponent implements ControlValueAccessor { constructor(@Self() @Optional() private control: … Read more
