将DataTemplate绑定字段设置为变量 [英] Setting DataTemplate Binding field as Variable

问题描述

大家好

在我的datagrid中，我正在使用DataTemplate.我的疑问是如何将绑定路径设置为变量，以便可以从代码中传递该变量的值.下面是代码.这里的"Binding Path = Rate"行，其中"Rate"是一个常数项.我想将"Rate"作为变量，并希望从代码中提供值.例如:在代码Rate ="NewRate"中；任何想法.... ???

在此先感谢..... :) :) :) :)

Hi All

In my datagrid I am using a DataTemplate. My doubt is that how I can set the binding path as variable.So that I can pass the value for that variable from code. Below is the code. Here the line "Binding Path=Rate", where "Rate" is a constant term. I want to make the "Rate" as a variable and want to supply the value from code. Eg: in code Rate="NewRate"; Any Idea....???

Thanks in Advance..... :) :) :) :)

<UserControl.Resources><DataTemplate x:Key="RateControlTemplate">
                <inputToolkit:Rating Background="Transparent" SelectionMode="Continuous" Name="RateControl" ValueChanged="Rating_ValueChanged"  ItemCount="6" Value="{Binding Path=Rate, Mode=TwoWay}" VerticalAlignment="Center">
                    <inputToolkit:Rating.RenderTransform>
                        <ScaleTransform ScaleX=".75"

                                            ScaleY="0.85" />
                    </inputToolkit:Rating.RenderTransform>
                </inputToolkit:Rating>
        </DataTemplate>
    </UserControl.Resources>

推荐答案

您需要为数据网格提供数据上下文，然后在数据上下文中更改Rate值.

如果您使用INotify实现此功能，则您的用户界面将自动更新.

You need to provide a datacontext for the datagrid and then change the Rate value within the datacontext.

If you implement this with INotify, your UI will update automatically.
