如何在按钮上显示Usercontrol Wpf页面单击 [英] How Do I Show A Usercontrol Wpf Page On Button Click

问题描述

我有类作为ModuleInitialization注册相应的视图。

我有以下视图。

CustomerMainView

StockMainVIew

SupplierMainView



----注册StockMainView的代码------

container.RegisterType< stockmainviewviewmodel> （）;

container.RegisterType< object，Menu.Menu>（）;

this.container.RegisterType< object，StockMainView>（typeof（StockMainView）.Name） ;

this.regionManager.RegisterViewWithRegion（RegionNames.ModulesMenuRegion，typeof（Menu.Menu））;

-----------结束--- --------------------------

其对应的ViewModel是

CustomerMainViewViewModel

StockMainViewViewModel

SupplierMainViewViewModel





现在我需要3个按钮，如客户，股票，供应商....所以当我点击Customer时，Customer视图应该得到D.相应地显示了其他人。



这个视图是UserControl WPF所以我无法使用.Show（）方法....





先谢谢..

I have classes as ModuleInitialization which registers the appropriate Views.
I have the following view.
CustomerMainView
StockMainVIew
SupplierMainView

----the code to register StockMainView------
container.RegisterType<stockmainviewviewmodel>();
container.RegisterType<object, Menu.Menu>();
this.container.RegisterType<object, StockMainView>(typeof(StockMainView).Name);
this.regionManager.RegisterViewWithRegion(RegionNames.ModulesMenuRegion, typeof(Menu.Menu));
-----------End-----------------------------
Its corresponding ViewModels are
CustomerMainViewViewModel
StockMainViewViewModel
SupplierMainViewViewModel


Now I need 3 Buttons like Customer,Stock,Supplier....so when I click on Customer the Customer view should get Displayed and hence the others accordingly.

This views are UserControl WPF so I am not able to use .Show() method....


Thanks in advance..

推荐答案

你必须在MainView.xaml中使用ContentControl

Hi,

you must use "ContentControl" in your MainView.xaml

<contentcontrol content="{Binding CurrentView}"></contentcontrol>

并将其绑定到ViewModel中的属性

and bind it to a property in your ViewModel

private object currentView;

public object CurrentView
{
    get
    {
        return currentView;
    }
    set
    {
        if(currentView != value)
        {
            currentView = value;

            OnPropertyChanged();
        }
    }
}

假设您调用了用户控制视图，例如UcViewBlue和UcViewRed

您可以通过激活ChangeCommandBlue命令切换到UcViewBlue。

Assuming you User Control views are called e.g. UcViewBlue, and UcViewRed
you could switch to "UcViewBlue" by excuting the "ChangeCommandBlue" Command.

private RelayCommand changeCommandBlue;

public ICommand ChangeCommandBlue
{
    get
    {
        if (changeCommandBlue == null)
        {
            changeCommandBlue = new RelayCommand(param => this.ChangeBlue());
        }

        return changeCommandBlue;
    }
}

private void ChangeBlue()
{
    CurrentView = new UcViewBlue();
}

祝你好运，
