How do I generate WPF controls through code
提问by
I was trying to get my head around XAML and thought that I would try writing some code.
我试图了解 XAML，并认为我会尝试编写一些代码。
Trying to add a grid with 6 by 6 column definitions then add a text block into one of the grid cells. I don't seem to be able to reference the cell that I want. There is no method on the grid that I can add the text block too. There is only grid.children.add(object), no Cell definition.
尝试添加具有 6 x 6 列定义的网格，然后将文本块添加到其中一个网格单元格中。我似乎无法引用我想要的单元格。网格上没有方法可以添加文本块。只有 grid.children.add(object)，没有 Cell 定义。
XAML:
XAML：
<Page x:Class="WPF_Tester.Page1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Page1"
Loaded="Page_Loaded">
</Page>
C#:
C＃：
private void Page_Loaded(object sender, RoutedEventArgs e)
{
//create the structure
Grid g = new Grid();
g.ShowGridLines = true;
g.Visibility = Visibility.Visible;
//add columns
for (int i = 0; i < 6; ++i)
{
ColumnDefinition cd = new ColumnDefinition();
cd.Name = "Column" + i.ToString();
g.ColumnDefinitions.Add(cd);
}
//add rows
for (int i = 0; i < 6; ++i)
{
RowDefinition rd = new RowDefinition();
rd.Name = "Row" + i.ToString();
g.RowDefinitions.Add(rd);
}
TextBlock tb = new TextBlock();
tb.Text = "Hello World";
g.Children.Add(tb);
}

I don't get the methods in autocomplete.

WPF makes use of a funky thing called attached properties. So in your XAML you might write this:
WPF 使用了一种叫做附加属性的时髦东西。所以在你的 XAML 中你可以这样写：
<TextBlock Grid.Row="0" Grid.Column="0" />
And this will effectively move the TextBlock into cell (0,0) of your grid.
这将有效地将 TextBlock 移动到网格的单元格 (0,0) 中。
In code this looks a little strange. I believe it'd be something like:
在代码中这看起来有点奇怪。我相信它会是这样的：
g.Children.Add(tb);
Grid.SetRow(tb, 0);
Grid.SetColumn(tb, 0);
Have a look at that link above - attached properties make things really easy to do in XAML perhaps at the expense of intuitive-looking code.
看看上面的链接 - 附加属性使在 XAML 中的事情变得非常容易，这可能会牺牲直观的代码。

The cell location is an attached property - the value belongs to the TextBlock rather than Grid. However, since the property itself belongs to Grid, you need to use either the property definition field or the provided static functions.
单元格位置是一个附加属性 - 该值属于 TextBlock 而不是 Grid。但是，由于属性本身属于 Grid，因此您需要使用属性定义字段或提供的静态函数。
TextBlock tb = new TextBlock();
//
// Locate tb in the second row, third column.
// Row and column indices are zero-indexed, so this
// equates to row 1, column 2.
//
Grid.SetRow(tb, 1);
Grid.SetColumn(tb, 2);

Use attached properties of the Grid class.
使用 Grid 类的附加属性。
in C#:
在 C# 中：
Grid.SetRow( cell, rownumber )In XAML:
在 XAML 中：
<TextBlock Grid.Row="1" />Also, I would advice if you do not use dynamic grids, use the XAML markup language. I know, it has a learning curve, but once you mastered it, it is so much easier, especially if you are going to use ControlTemplates and DataTemplates! ;)
另外，如果您不使用动态网格，我会建议您使用 XAML 标记语言。我知道，它有一个学习曲线，但是一旦你掌握了它，它就会容易得多，特别是如果你要使用 ControlTemplates 和 DataTemplates！;)

Here is some sample
这是一些示例
Grid grid = new Grid();
// Set the column and row definitions
grid.ColumnDefinitions.Add(new ColumnDefinition() {
Width = new GridLength(1, GridUnitType.Auto) });
grid.ColumnDefinitions.Add(new ColumnDefinition() {
Width = new GridLength(1, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition() {
Height = new GridLength(1, GridUnitType.Auto) });
grid.RowDefinitions.Add(new RowDefinition() {
Height = new GridLength(1, GridUnitType.Auto) });
// Row 0
TextBlock tbFirstNameLabel = new TextBlock() { Text = "First Name: "};
TextBlock tbFirstName = new TextBlock() { Text = "John"};
grid.Children.Add(tbFirstNameLabel ); // Add to the grid
Grid.SetRow(tbFirstNameLabel , 0); // Specify row for previous grid addition
Grid.SetColumn(tbFirstNameLabel , 0); // Specity column for previous grid addition
grid.Children.Add(tbFirstName ); // Add to the grid
Grid.SetRow(tbFirstName , 0); // Specify row for previous grid addition
Grid.SetColumn(tbFirstName , 1); // Specity column for previous grid addition
// Row 1
TextBlock tbLastNameLabel = new TextBlock() { Text = "Last Name: "};
TextBlock tbLastName = new TextBlock() { Text = "Smith"};
grid.Children.Add(tbLastNameLabel ); // Add to the grid
Grid.SetRow(tbLastNameLabel , 1); // Specify row for previous grid addition
Grid.SetColumn(tbLastNameLabel , 0); // Specity column for previous grid addition
grid.Children.Add(tbLastName ); // Add to the grid
Grid.SetRow(tbLastName , 1); // Specify row for previous grid addition
Grid.SetColumn(tbLastName , 1); // Specity column for previous grid addition
