如何在运行时将 wpf 控件添加到特定的网格行和单元格? [英] How to add wpf control to particular grid row and cell during runtime?

问题描述

我的 WPF窗口"中有以下网格(是的类窗口)；

I have the following grid in my WPF "Window" (yes the class Window);

<Grid Name="RequiredGrid">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="70" />
                <ColumnDefinition Width="*" />
            </Grid.ColumnDefinitions>
        </Grid>

根据传入窗口的内容，我想一次将项目添加到该网格中的一行.即，我想在左列中添加一个标签，在右列中添加一个文本框.我相信我知道如何通过在后面的代码中执行以下操作来添加新行以保存新数据:

Depending on whats passed into the window, I want to add items into this grid one row at a time. Namely, I want to add a Label in the left column and a TextBox in the right column. I believe I know how to add new rows for holding new data by doing the following in the code behind:

RequiredGrid.RowDefinitions.Add(new RowDefinition());

问题是，在我创建了标签和文本框之后.

Problem is, after I've created my Label and my TextBox.

Label AttrLabel = new Label();
TextBox AttrTextBox = new TextBox();

我真的不知道如何将它放入窗口以便显示.我看到一些线程说，做这样的事情:

I don't really know how to get it into the Window so it gets displayed. I've seen some threads that say, do something like this:

this.Controls.Add(AttrLabel);
this.Controls.Add(AttrTextBox);

这有两个问题.1)我的 Window 类没有这个控件"属性或其他任何东西.并且 2) 这不会帮助我指定每个 UI 项的行和列.

There are two problems with this. 1) My Window class doesn't have this "Controls" property or whatever. And 2) This wouldn't help me specify the row and column of each UI item.

现在在 XAML 中，我可以很容易地用这样的方式指定行和列:

Now in XAML, Id be easy to specify the row and column with something like this:

 <Label Grid.Column="0" Grid.Row="0"/>

不过，这违背了我的意图的动态性".有谁知道如何让我动态创建的 UI 元素显示在我的窗口中，并指定它将显示在网格中的哪一行和哪一列.

This defeats the "dynamic-ness" of my intent here though. Does anyone know how I can get my dynamicaly created UI elements to display in my Window and specify which row and column it will show up in the grid.

推荐答案

Grid.Row 和 Grid.Column 属性是 附加属性，因此不像普通的 .net 属性那样设置.从代码中设置它们的正确方法是:

The Grid.Row and Grid.Column properties are Attached Properties, and as such are not set like normal .net properties. The right way to set them from code is:

Grid.SetRow(someLabel, 0);
Grid.SetColumn(someLabel, 0);

您应该能够在将它们添加到 Grid 对象的 Children 集合之前或之后执行此操作，但在添加控件之前设置它们应该可以防止任何可能的闪烁.

You should be able to do this before or after adding them to the Grid object's Children collection, but setting them before adding the control should prevent any possible flickering.
