![]() ![]() In this situation, request form template helps the most in organizing and keeping the things in order. So you can easily get the things which you willing to get in order or want to have the things in keeping the order after filling request form. ![]() In department of information technology, there are bundles of requests ranging from network problem to the hardware malnutrition. Filling of request form is very simple in use because it has all the important sections which are important to request the things to the higher authorities. Request form is using in almost all fields of life. You may simply fill the request form and get the things or goods you need the most to complete business operations or processes. For example, if there is something in low quantity or missing from the store of company, you may need to fill out and send request form to concerned department or entity in order to get the request for required thing or stuff fulfilled. Public override void WillDisplay(UITableView tableView, UITableViewCell cell, Foundation.NSIndexPath indexPath)Ĭell.Request form is a document which is used to make formal request for something in professional manner. Internal ListView2Delegate(ListView listView) oldDelegate = (UITableViewSource)Control.Delegate Ĭontrol.Delegate = new ListView2Delegate(e.NewElement) Ĭlass ListView2Delegate : UITableViewDelegate Protected override void OnElementChanged(ElementChangedEventArgs e) Public partial class ListView2Renderer : ListViewRenderer Protected override void OnElementPropert圜hanged(object sender, Propert圜hangedEventArgs e)īase.OnElementPropert圜hanged(sender, e) įoreach (var cell in Control.VisibleCells)Ĭell.SelectionStyle = UITableViewCellSelectionStyle.None įor android you can add this style in your values/styles.xml renderer: public class CustomListViewRenderer : ListViewRenderer This is to be written in the platform project of iOS by creating a new Custom ListView renderer in your Forms project. If you want you can change it with other colors from UITableViewCellSelectionStyle. This example is to set the color of tapped item to transparent. In order to set the color of highlighted item you need to set the color of cell.SelectionStyle in iOS. I hope this solution will be usefull for somebody My example is extracted by a listview of places which are in a Xamarin Forms Maps (same contentpage). Propert圜hanged?.Invoke(this, new Propert圜hangedEventArgs(nameof(PlaceItemSelected))) Return (Color)value = Color.Yellow ? true : false Public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) Return (bool)value ? Color.Yellow : Color.White Public object Convert(object value, Type targetType, object parameter, CultureInfo culture) In code (MVVM) i save the lastitemselected by a boolToColor Converter i update background color public class BoolToColorConverter : IValueConverter I have & use a solution similar to custom renderers, in xaml i bind background ViewCell Property xmlns:customuicontrols="clr-namespace:MyMobileApp.CustomUIControls"Īnd don't forget to make actual use of the new Custom comtrol in your XAML. xaml page, you need to add an XMLNS reference back to the new CustomViewCell. Var customTextCell = sender as CustomTextCell ĬellCore.SetBackgroundColor(()) ĬellCore.SetBackground(unselectedBackground) I had to create a property to track the selection because cellCore.Selected is always false. Protected override void OnCellPropert圜hanged(object sender, Propert圜hangedEventArgs args)īase.OnCellPropert圜hanged(sender, args) UnselectedBackground = cellCore.Background We assume that no cells will be selected on creation. Save original background to rollback to it when not selected, Protected override GetCellCore(Cell item, convertView, ViewGroup parent, Context context)ĬellCore = base.GetCellCore(item, convertView, parent, context) Var cell = base.GetCell(item, reusableCell, tv) īackgroundColor = (),Īndroid public class CustomTextCellRenderer : TextCellRenderer Public override UITableViewCell GetCell(Cell item, UITableViewCell reusableCell, UITableView tv) IOS public class CustomTextCellRenderer : TextCellRenderer On your page do something like this: MyModel model1 = new MyModel() I am only including the relevant code here beyond the typical text, image, etc. I am assuming ViewCells, but this should work for Text or Image cells as well. This is a mash-up of lots of googling, so thanks to anyone who I may have borrowed from. It uses only binding and does not require custom renderers (which seems rare). It looks like there is actually a cross-platform way to do this that works on both iOS and Android (not sure about Windows). ![]()
