文本块不想调整网格列

Question

我正在准备控件以显示一些数据。它以以下方式构建：

-> ScrollViewer
--> StackPanel
---> Border
----> Grid
---> Border
----> Grid
...
---> Border
----> Grid

这是我的每一项的代码

public class PresenterItem : Border
{
// Variables
private Submission submission;
private int index;
private Grid grid = new Grid();
// Constructor
public PresenterItem(int i, Submission subm)
{
index = i;
submission = subm;
Child = grid;
Background = Global.GET_BRUSH("ItemBackground");
CornerRadius = new CornerRadius(5);
Margin = new Thickness(0, 0, 0, 10);
Padding = new Thickness(5);
grid.ShowGridLines = true;

grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(40, GridUnitType.Pixel) });
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(2, GridUnitType.Star) });
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(2, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(40, GridUnitType.Pixel) });
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(30, GridUnitType.Pixel) });
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) });
InsertContent();
}
private Label CreateLabel(int row, int column, string content, int columnSpan = 1)
{
Label newLabel = new Label();
newLabel.Content = content;
Grid.SetRow(newLabel, row);
Grid.SetColumn(newLabel, column);
Grid.SetColumnSpan(newLabel, columnSpan);
grid.Children.Add(newLabel);
return newLabel;
}
private TextBlock CreateTextBlock(int row, int column, int columnSpan = 1)
{
TextBlock newTextBlock = new TextBlock();
newTextBlock.Foreground = Brushes.Silver;
Grid.SetRow(newTextBlock, row);
Grid.SetColumn(newTextBlock, column);
Grid.SetColumnSpan(newTextBlock, columnSpan);
grid.Children.Add(newTextBlock);
return newTextBlock;
}
private void InsertContent()
{
// Number
Label number = CreateLabel(0, 0, $"#{index + 1}");
number.HorizontalAlignment = HorizontalAlignment.Center;
number.VerticalAlignment = VerticalAlignment.Center;
number.FontSize = 17;
// Header
Label header = CreateLabel(0, 1, $"{submission.Name} ({submission.Rank})");
header.Foreground = Global.GET_BRUSH("HeaderForeground");
header.HorizontalAlignment = HorizontalAlignment.Left;
header.VerticalAlignment = VerticalAlignment.Center;
header.FontSize = 17;
// Timestamp
TextBlock timestamp = CreateTextBlock(0, 2);
timestamp.Inlines.Add(new Run("Timestamp"));
timestamp.Inlines.Add(new Run($"{submission.Timestamp}") { Foreground = Global.GET_BRUSH("HeaderForeground") });
timestamp.HorizontalAlignment = HorizontalAlignment.Right;
timestamp.VerticalAlignment = VerticalAlignment.Center;
timestamp.FontSize = 13.5;
// Range
TextBlock range = CreateTextBlock(1, 1);
range.Inlines.Add(new Run("Some text "));
range.Inlines.Add(new Run($"{submission.Range.ToStringWithDayNames()}") { Foreground = Global.GET_BRUSH("HeaderForeground") });
range.HorizontalAlignment = HorizontalAlignment.Left;
range.VerticalAlignment = VerticalAlignment.Center;
range.Margin = new Thickness(5, 0, 0, 0);
range.FontSize = 13.5;
// Conflict
Label conflict = CreateLabel(1, 2, "Nie wykryto konfliktu");
conflict.Foreground = Global.GET_BRUSH("GreenForeground");
conflict.HorizontalAlignment = HorizontalAlignment.Right;
conflict.VerticalAlignment = VerticalAlignment.Center;
conflict.FontSize = 13.5;
// Content
TextBlock content = CreateTextBlock(2, 1, 2);
content.Inlines.Add(new Run($"{submission.Content}"));
cotent.HorizontalAlignment = HorizontalAlignment.Left;
content.VerticalAlignment = VerticalAlignment.Top;
content.Margin = new Thickness(5, 0, 0, 0);
content.TextWrapping = TextWrapping.WrapWithOverflow;
content.FontSize = 13.5;
}

它看起来像

它非常有效，但当我添加最后一个TextBlock时，整个控件向右拉伸。在设计器中，创建元素的方法是一样的，但在代码中却没有。我做错了什么？

我想通过第1列和第2列的所有位置都具有相同的宽度来实现这种效果。我想要什么

Answer 1

您必须在StackPanel中将依赖属性Grid.IsSharedSizeScope设置为true，然后将每个ColumnDefinition的属性SharedSizeGroup设置为定义相同大小组的字符串。

Answer 2

我自己处理了这个问题。如果有人会像我一样有同样的问题，我会写下如何修复它。

在我的应用程序初始化ScrollViewer的地方，我将属性HorizontalScrollBarVisibility设置为Hidden。将此属性设置为Disabled后，一切都开始正常工作。
