由 丶灬走出姿态 提交于 2020-02-07 02:36:23
问题 I'm trying to add button to this datatemplate but I cannot access the ICommand EditTripClick Command from the ViewModel. So I am wondering is it possible to access it although I am in a datatemplate? Example code of what I want to do <CommandBar OverflowButtonVisibility="Auto"> <AppBarButton Label="Add trip" Icon="Add" Command="{x:Bind ViewModel.NewTripClickCommand}"/> <AppBarButton Label="Refresh" Icon="Refresh" Command="{x:Bind ViewModel.RefreshClickCommand}"/> </CommandBar> <controls

Silverlight multiple line textbox

由 限于喜欢 提交于 2020-02-06 05:38:25
问题 I have looked at several code snippets where people suggest that the AcceptsReturn property of a textbox in Silverlight will enable multiple lines. My problem however is when I add a textbox with said property and explicity set the height or allow it to fill the container, the text sits vertically in the middle of the textbox. <Grid x:Name="LayoutRoot" > <TextBox TextWrapping="Wrap" Text="TextBox" AcceptsReturn="True"/> </Grid> I need the text to anchor to the top of the textbox. 回答1: Ensure

由 浪尽此生 提交于 2020-02-06 03:58:12
问题 So I have a MenuItem (within a ContextMenu, if it really makes a difference, don't think it does). I want to display an icon within the MenuItem using the MenuItem.Icon property.

But what if I want to specify the size of the icon with Height and Width ? Search on the web reveals that it should be 32, some say it should be 20. 20 works the

问题 I'm getting InvalidOperationException . This code is running in a thread. I've delegate it to the UI thread to handle the UI. Is the problem occuring because of my resources?

RadioButton TwoWay Binding Issues

由 天大地大妈咪最大 提交于 2020-02-05 09:24:50
问题 Consider the below simplified application, which allows you to select between two elements, each of which has A and B boolean properties that are bound to radio buttons. The idea is that you should be able to set A/B independently for each element and if you switch between elements, the radio buttons should reflect the flags for that element. This isn't what happens however. ViewModel: using System; using System.Collections.Generic; using System.ComponentModel; using System.Linq; using System
