如何在XAML for WPF中使用Corporate if语句 [英] how I can in corporate if Statements in XAML for WPF

问题描述

如何在XAML中合并if语句?

我有一个主DataGrid.我绑定到数据库.但基于各种按钮，将打开数据库中的不同表.尽管每个表都链接到单个数据库，但每个表都有不同的列.因此，基于单击按钮，我只想执行某些XAML代码.其他代码将无效.它需要使用if语句.我该如何处理这种情况.我只想维护一个窗口来夸耀所有表.

也就是说，如果Mainwindow.xaml.cs中的语句是< b> sql ="Select * from Authors"</b>

执行此Segment< .. segment1 ..> Mainwidow.xaml中的残差

如果Mainwindow.xaml.cs中的语句为< b> sql ="Select * from ISBN"</b>

执行此Segment< .. segment2 ..> Mainwidow.xaml中的残缺物

任何类型的帮助都将得到感谢

在此先感谢

how I can incorporate if statements in XAML?

I have a Main DataGrid. which i binded to a Database. but based on various button click different tables from the Database will be opened. each table have dissimilar columns although it is linked to a single database.so based on the button click I want to execute only certain XAML codes . other codes will not be active. it requires the use of an if statement. how I can approach this situation. I want to maintain only one window to boast all tables .

ie if the statement in Mainwindow.xaml.cs is <b>sql="Select*from Authors"</b>

execute this Segment<..segment1..> of satement in Mainwidow.xaml

if the statement in Mainwindow.xaml.cs is <b>sql="Select*from ISBN"</b>

execute this Segment<..segment2..> of satement in Mainwidow.xaml

any type of help will be appreaciated

thanks in advance

推荐答案

一种方法可以是:

为每个单独的具有网格和其他功能的表创建一个user control.然后将 user control 动态加载到要在其中加载所有控件的窗口中.

例如，您可以在主窗口中添加StackPanel ，并根据您在if 声明之后做出的决定将新创建的用户控件添加到其Children 中.
在这里看看:

希望对您有所帮助.

One approach can be this :

Make a user control for every individual tables which have a grid and other facilities prepared in there. Then dynamically load that user control into the window which you want to load all controls in there.

For example you can add a StackPanel to your main window and add newly created user control to its Children based on decision made after your if statements.
