如何在StackPanel添加列 [英] How to add Columns at StackPanel

问题描述

您好我可以问一个问题吗？我试图在StackPanel添加Columns，但我不知道如何使这个解决方案工作。

Hello can I ask a question? I tried to add Columns at StackPanel, but I've not idea, how to make this solution work.

//xaml
<Grid>
        <StackPanel x:Name="sp">
            <Grid x:Name="GridPanel" Grid.Row="0" Grid.Column="0">
                
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>
                
            </Grid>
        </StackPanel>
    </Grid>

//C#
TextBox tb = new TextBox();
            tb.Height = 60;
            tb.Width = 100;
            Grid.SetRow(tb, 0);
            Grid.SetColumn(tb, 0);
            //this.GridPanel.Children.Add(tb);
            Button b = new Button();
            b.Content = "Button";
            b.Width = 100;
            b.Height = 60;
            b.Click += new RoutedEventHandler(new_but);
            Grid.SetRow(b,0);
            Grid.SetColumn(b,1);
            //this.GridPanel.Children.Add(b);

如何添加列，我用 this.sp.Children.Add

推荐答案

StackPanel不支持列，它只有一列可以水平或垂直堆叠。 Grid（您确实使用它）支持列和行。您的代码甚至没有引用Grid来添加列。



您的代码几乎就在那里。下面看一下，

StackPanel doesn't support columns, it has only one column that can be stacked horizontally or vertically. Grid (which you are indeed using) supports columns and rows. Your code doesn't even refer to the Grid for adding the columns.

Your code, is almost there. Here have a look below,

sp.Children.Add(UIElement); // Adds a new element "in the stack"

你需要使用这段代码，

Whereas you need to use this code,

foreach (var child in sp.Children) {
   // check the type of children
   if(child is Grid) {
      // the grid, which supports columns.
      // Now, add columns to the "child".
   }
}

现在，当你改变定义时 child ，它会改变StackPanel中存在的网格。我可以问，为什么当一切都必须在网格中时，你甚至使用StackPanel。 Grid已作为此StackPanel的父级存在。

Now, when you will alter the definition of child, it would alter the grid that is present inside the StackPanel. Can I ask, why are you even using a StackPanel when everything has to be in a Grid. Grid is already present as a parent for this StackPanel.

我只是在程序中编写了一个动态构建的600代码。你说为什么stakpanel而不是网格。因为我不知道一切都会变成这样！只需在文本框附近添加一个Knop来更改数据库

I just wrote a 600 code in the program all built dynamically. And you say why stakpanel instead grid. Because I did not know that everything will turn so! just had to add one Knop near textbox to change the database
