custom-renderer

问题 I need to remove the default underline as seen in this image EntryCell Example I have already created a custom Renderer for Android which is working fine on the device. I am able to color the EntryCells along with other UI tweaks. However I need to get rid of the line, I am using a placeholder to make it obvious that it is an EntryCell so I don't want the line to be visible. What needs to be added to achieve this using System; using System.ComponentModel; using Android.Content; using Android

问题 Is there a way to set a border radius on an Entry in Xamarin's XAML, or by using a custom renderer or something ?

问题 I have a custom JSF component renderer that renders pagination component for datatables, but it hasn't ajax behavior . I learned that it could be done by inserting ajax to encode method or by making support of f ajax tag. Unfortunately I'm not very familiar with ajax, so could you please tell me how I should modify this code to make it ajaxable? @FacesRenderer(componentFamily="javax.faces.Command", rendererType="com.component.Pager") public class PagerRenderer extends Renderer { private
