使用WPF-MVVM中的用户控件值绑定数据网格行 [英] Bind datagrid row with user control values in WPF-MVVM

问题描述

我在一个窗口中有多个用户控件。每个用户控件都有一个文本框（txtGoodQty）。双击该文本框打开一个窗口，里面有一个数据网格。我想将用户控件的值绑定到数据网格行。如何使用MVVM实现它？

我们可以在这里使用依赖属性，但我不知道如何使用它进行绑定。



我尝试了什么：



我做了这个

I have multiple user control's in a window.Every User Control has a text box (txtGoodQty).On Double click of that text box opens a Window which has a data grid inside.I want to bind the user control's value to the data grid row.How can i achieve it using MVVM?
Can we use dependency property here, but i am not aware how to use it for binding.

What I have tried:

I did this

<TextBox.InputBindings>
               <MouseBinding MouseAction="LeftDoubleClick" Command="{Binding DataContext.testmethod,
                                       RelativeSource={RelativeSource FindAncestor,
                                       AncestorType={x:Type UserControl}}}"/>
               <!--CommandParameter="{Binding .}"/>-->
           </TextBox.InputBindings>

在某些方法中我称之为窗口的show属性。

但现在我我对用户控件值绑定到datagrid行感到困惑。

and in the somemethod i called the show property of window.
But now I am stucked up with bindings of user control values to the datagrid row.

推荐答案

我对你要做的事情感到有些困惑，但你确实有CommandParameter哪个传递控件的值。

I am somewhat confused about what you are trying to do, but you do have the CommandParameter with which to pass the control's value.
