wpf 如何以编程方式设置网格行和列位置

How to set Grid row and column positions programmatically

提问by Vinod

I have two Grids inside a Stackpanel. The first grid is named as GridX. Initially, inside the grid, there is a 2D array of Textboxes(RowDefs/ColumnDefs). The TextBox definition in XAML is

我在 Stackpanel 中有两个网格。第一个网格被命名为 GridX。最初，在网格内部，有一个二维文本框数组（RowDefs/ColumnDefs）。XAML 中的 TextBox 定义是

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

I want to add a TextBlockprogrammatically in the same position as part of GridX.

我想以编程方式在与 GridX 的一部分相同的位置添加一个TextBlock。

The effect must be like this

效果一定是这样的

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

How to add this. I have tried this:

这个怎么加。我试过这个：

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

But failed.

但是失败了。

Again I tried this:

我再次尝试了这个：

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;    

Now the problem is that TextBlock is not visible. TextBox hides it. I appreciate your help.

现在的问题是 TextBlock 不可见。文本框隐藏它。我感谢您的帮助。

For attached properties you can either call SetValue on the object for which you want to assign the value:

对于附加属性，您可以在要为其分配值的对象上调用 SetValue：

tblock.SetValue(Grid.RowProperty, 4);

Or call the static Set method (not as an instance method like you tried) for the property on the owner type, in this case SetRow:

或者为所有者类型上的属性调用静态 Set 方法（不是像您尝试的那样作为实例方法），在本例中为 SetRow：

Grid.SetRow(tblock, 4);

Here is an example which might help someone:

这是一个可能对某人有所帮助的示例：

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);

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);
}

Try this:

尝试这个：

                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++)

                            FontSize = 10,

                        Grid.SetColumn(t1, j);
                        grid.Children.Add(t1); //Add the Label Control to the Grid created
                    }
                }
