binding

问题 I've got two WPF Toolkit DataGrids , I'd like so that when the user resizes the first column in the first grid, it resizes the first column in the second grid. I've tried binding the width of the DataGridColumn in the second grid to the appropriate column in the first grid, but it doesn't work. I'd prefer to use all xaml, but I'm fine with using code behind as well. <tk:DataGrid Width="100" Height="100"> <tk:DataGrid.Columns> <tk:DataGridTextColumn x:Name="Column1" Width="50"/> </tk:DataGrid

问题 I've a read only property I need to display in a textbox, and getting this error at runtime. I've set IsEnabled="False" , IsReadOnly="True" - no luck. Other searches say the readonly should fix it, but not for me. I've got an ugly workaround by adding a dummy setter... 回答1: It's hard to guess without code, but you should be able to set the BindingMode to OneWay. <TextBox Text="{Binding Path=MyProperty, Mode=OneWay}" /> or from code: Binding binding = new Binding(); binding.Mode = BindingMode

问题 I have a dependency property of type collection, when its callback fires based on the count I need to set the visibility of some of the controls on the screen. But the controls remains Collapsed all the time. As per the code, one control remains visible all the time. XAML binding is <TextBlock Text="106 search results for 'a'" Margin="5,0,100,0" Visibility="{Binding CountLabelVisibleReverse, Converter={StaticResource VisibilityConverter}}"/> <StackPanel Grid.Row="1" Orientation="Horizontal"

问题 I have a custom web component treez-tab-folder . As the name suggests it represents a tab folder. Here is a jsfiddle and some image to demonstrate its usage (might require Chrome browser to work correctly): https://jsfiddle.net/fg4dL2rx/ I would like to use vue.js to bind the properties of a JavaScript object to some attributes of the tab folder. If I use a div inside a treez-tab as target element for the Vue instance ( el: '#firstContent' ), the binding works as expected (also see above

问题 Being new to WPF, and its apparently amazing ability to change, bind, enable, and otherwise manipulate. I'm trying to get a mental overview of what is happening and hope some can either confirm or correct my readings. Before WPF, you have delegates and events. You could have a dozen controls all listening (via being registered to the event), so when the event fires, all other controls will be notified automatically and can act on however they were so coded. Such as... From Code Behind, you

问题 I am c# and silverlight-5 beginner. First i had to create object by deserializing an xml string. I have done that succesfully but now my next step is to create GUI using the object elements. I have idea that i have to use " IValueConverter " for doing this. But how that i dont know. My Program class which contains the object is like this: using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System

问题 Error CS0234: The type or namespace name IBitmap' does not exist in the namespace Com.Sushi.Hangover'. Are you missing an assembly reference? I have an Android binding project which has classes that are inheriting from multiple interfaces but these interfaces are not been generated and thus all of the public classes that depend upon them are failing to bind. Java Class: abstract interface Bitmap { ~~~ (methods removed) } api.xml: <interface abstract="true" deprecated="not deprecated" final=
