WPF：将DataGrid列标题绑定到ViewModel [英] WPF: Binding DataGrid column header to ViewModel

问题描述

我有一个datagrid我手动指定列（AutoGenerateColumns =false）。我使用MVVM，我想绑定列标题（文本），以便我从我的ViewModel中获取它。但是我找不到一个办法。

最近我发现的是：
Wpf工具包。将DataGrid列标题绑定到DynamicResource
...这是一个技巧，您可以使用该技巧将列标题绑定到在XAML中静态声明的字符串。但是我需要从我的ViewModel中获取它。

我想要这样做的原因是我要用作列标题的文本将显示在整个GUI。要确保它实际上是一样的，我想要在代码中可用。我不能将这些字符串存储在XAML资源文件中，因为我还需要在代码中访问这些字符串。

我正在使用TeleRik的RadGridView，但是猜猜我会有同样的问题，如果我的标准网格视图。

任何提示赞赏！谢谢！

解决方案

在Silverlight中，我尝试了以下内容：

 < DataGridTextColumn Header ={Binding ElementName = LayoutRoot，Path = DataContext.MyProperty}... /> （LayoutRoot是Window / UserControl中的第一个控件，MyProperty是VM中的一个）
  

$ b它不起作用，因为列无法访问视觉树。

可能值得一试在WPF与您的网格。

I have a datagrid in which i manually specify the columns (AutoGenerateColumns="false"). I'm using MVVM and I would like to bind the column header (the text) so that I get it from my ViewModel. But I can't find a way to do that.

The closest thing I've found is this: Wpf Toolkit. Bind DataGrid Column Header to DynamicResource ...which is a "trick" with which you can bind the column header to a string statically declared in XAML. But I need to get it from my ViewModel.

The reason I want to this is that the text I want to use as column header will be shown in several places throughout the GUI. To get make sure it actually is the same everywhere I want to have it available in code. And I can't store the strings in a XAML resource file because I also need access to these strings in code.

I'm using a RadGridView from TeleRik, but I guessing I'd have the same problem if I the standard gridview.

Any tips appreciated! Thanks!

解决方案

In Silverlight I have tried the following:

<DataGridTextColumn Header="{Binding ElementName=LayoutRoot, Path=DataContext.MyProperty}" ... />

(LayoutRoot is the first control in the Window/UserControl, MyProperty is something in the VM) It does not work because the column has no access to the visual tree.

It may be worth a try in WPF with your Grid.
