Question

我在Stackpanel中有两个网格。第一个网格名为GridX。最初在网格内部有一个文本框的2D数组（RowDefs / ColumnDefs）。 XAML中的TextBox定义是

<TextBox x:Name="A1" Grid.Row="4" Grid.Column="5" TextAlignment="Center" />

我想以编程方式在GridX中添加 TextBlock 。

效果必须像这样

<TextBlock Grid.Row="4" Grid.Column="5"
    HorizontalAlignment="Left" VerticalAlignment="Top" Text="10" FontSize="8"/>

如何添加此内容。我试过这个：

TextBlock tblock = new TextBlock();
GridX.SetColumn(tblock, cIndex);
GridX.SetRow(tblock, rIndex);

但失败了。

我再试一次：

int rIndex = Grid.GetRow(txtBox);
int cIndex = Grid.GetColumn(txtBox);                               

                            TextBlock tblock = new TextBlock();
                            tblock.VerticalAlignment = VerticalAlignment.Top;
                            tblock.HorizontalAlignment = HorizontalAlignment.Left;
                            tblock.FontSize = 8;
                            tblock.Text = rc[i, j - 1];

                            Grid.SetColumn(tblock, cIndex);
                            Grid.SetRow(tblock, rIndex);


                            txtBox.MaxLength = 1;

现在问题是TextBlock不可见.TextBox隐藏它。你能帮忙吗

Answer 1

对于附加属性，您可以在要为其指定值的对象上调用SetValue：

tblock.SetValue(Grid.RowProperty, 4);

或者为所有者类型的属性调用静态Set方法（而不是像你尝试过的实例方法），在本例中为SetRow：

Grid.SetRow(tblock, 4);

Answer 2

这是一个可以帮助某人的例子：

Grid test = new Grid();
test.ColumnDefinitions.Add(new ColumnDefinition());
test.ColumnDefinitions.Add(new ColumnDefinition());
test.RowDefinitions.Add(new RowDefinition());
test.RowDefinitions.Add(new RowDefinition());
test.RowDefinitions.Add(new RowDefinition());

Label t1 = new Label();
t1.Content = "Test1";
Label t2 = new Label();
t2.Content = "Test2";
Label t3 = new Label();
t3.Content = "Test3";
Label t4 = new Label();
t4.Content = "Test4";
Label t5 = new Label();
t5.Content = "Test5";
Label t6 = new Label();
t6.Content = "Test6";

Grid.SetColumn(t1, 0);
Grid.SetRow(t1, 0);
test.Children.Add(t1);

Grid.SetColumn(t2, 1);
Grid.SetRow(t2, 0);
test.Children.Add(t2);

Grid.SetColumn(t3, 0);
Grid.SetRow(t3, 1);
test.Children.Add(t3);

Grid.SetColumn(t4, 1);
Grid.SetRow(t4, 1);
test.Children.Add(t4);

Grid.SetColumn(t5, 0);
Grid.SetRow(t5, 2);
test.Children.Add(t5);

Grid.SetColumn(t6, 1);
Grid.SetRow(t6, 2);
test.Children.Add(t6);

Answer 3

尝试一下：

                Grid grid = new Grid(); //Define the grid
                for (int i = 0; i < 36; i++) //Add 36 rows
                {
                    ColumnDefinition columna = new ColumnDefinition()
                    {
                        Name = "Col_" + i,
                        Width = new GridLength(32.5),
                    };
                    grid.ColumnDefinitions.Add(columna);
                }

                for (int i = 0; i < 36; i++) //Add 36 columns
                {
                    RowDefinition row = new RowDefinition();
                    row.Height = new GridLength(40, GridUnitType.Pixel);
                    grid.RowDefinitions.Add(row);
                }

                for (int i = 0; i < 36; i++)
                {
                    for (int j = 0; j < 36; j++)
                    {
                        Label t1 = new Label()
                        {
                            FontSize = 10,
                            FontFamily = new FontFamily("consolas"),
                            FontWeight = FontWeights.SemiBold,
                            BorderBrush = Brushes.LightGray,
                            BorderThickness = new Thickness(2),
                            HorizontalContentAlignment = HorizontalAlignment.Center,
                            VerticalContentAlignment = VerticalAlignment.Center,
                        };
                        Grid.SetRow(t1, i);
                        Grid.SetColumn(t1, j);
                        grid.Children.Add(t1); //Add the Label Control to the Grid created
                    }
                }

Answer 4

for (int i = 0; i < 6; i++)
{
    test.ColumnDefinitions.Add(new ColumnDefinition());

    Label t1 = new Label();
    t1.Content = "Test" + i;

    Grid.SetColumn(t1, i);
    Grid.SetRow(t1, 0);
    test.Children.Add(t1);
}
