WPF Routed Command with Bindings per-Tab

由 拜拜、爱过 提交于 2019-12-01 10:09:27
问题 I intended to disable and enable the Buttons outside the TabControl, just like those inside the TabItem when the current tab is changed. But the CommandBindings of the TabItem do not seem to impact "up" the visual tree. What is the right way to do this? With this XAML: <Window x:Class="WpfApplication10.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication10" Title=

Getting parent of new tab after adding to bound TabControl (mvvm)

I'm adding a close button to my tabs using the following guide: http://www.codeproject.com/Articles/84213/How-to-add-a-Close-button-to-a-WPF-TabItem This has become a problem because the event uses the 'parent' of the added tab to remove that tab from the tabcontrol. I'm binding the tab control using mvvm, so the parent property is apparently not being set and giving me a null reference exception for the parent when the event tries to remove from it. Here's the binding so you get the idea: <TabControl Name="tabControl" Margin="0,22,0.2,-5.2" ItemsSource="{Binding Tabs}" Background="#FF4C76B2"/

How can i make WinForms TabPage header width fit it's title? Here is the problem. The native Windows tab control allows overriding the default minimum tab width. Sadly that capability is not exposed in the TabControl wrapper class. That's fixable though. Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form. using System; using System.Windows.Forms; class MyTabControl : TabControl { protected override void OnHandleCreated(EventArgs e) { base.OnHandleCreated(e); // Send TCM_SETMINTABWIDTH SendMessage(this.Handle,
