我已经动态地创建了一个包含两列的 Grid 控件，并使用第一列中的数据库中的数据和第二列中的文本框控件来填充它的行。但是最后两行网格重叠了。以下是我的代码片段。

    if (comboBox1.SelectedIndex > 0)
    {
        // Create the Grid
        Grid DynamicGrid = new Grid();
        DynamicGrid.Width = 400;
        DynamicGrid.HorizontalAlignment = HorizontalAlignment.Left;
        DynamicGrid.VerticalAlignment = VerticalAlignment.Top;
        DynamicGrid.ShowGridLines = true;
        DynamicGrid.Background = new SolidColorBrush(Colors.LightSteelBlue);

        //Adding columns to datagrid
        ColumnDefinition gridCol1 = new ColumnDefinition();
        ColumnDefinition gridCol2 = new ColumnDefinition();
        DynamicGrid.ColumnDefinitions.Add(gridCol1);
        DynamicGrid.ColumnDefinitions.Add(gridCol2);

        // Add first column header
        TextBlock txtBlock1 = new TextBlock();
        txtBlock1.Text = "Particulars";
        txtBlock1.FontSize = 14;
        txtBlock1.FontWeight = FontWeights.Bold;
        txtBlock1.Foreground = new SolidColorBrush(Colors.Green);
        txtBlock1.VerticalAlignment = VerticalAlignment.Top;
        Grid.SetRow(txtBlock1, 0);
        Grid.SetColumn(txtBlock1, 0);

        // Add second column header
        TextBlock txtBlock2 = new TextBlock();
        txtBlock2.Text = "Amount";
        txtBlock2.FontSize = 14;
        txtBlock2.FontWeight = FontWeights.Bold;
        txtBlock2.Foreground = new SolidColorBrush(Colors.Green);
        txtBlock2.VerticalAlignment = VerticalAlignment.Top;
        Grid.SetRow(txtBlock2, 0);
        Grid.SetColumn(txtBlock2, 1);

        //// Add column headers to the Grid
        DynamicGrid.Children.Add(txtBlock1);
        DynamicGrid.Children.Add(txtBlock2);

        RowDefinition gridRow;
        TextBlock par;
        TextBox amt;

        int i = 1;
        string pjt = comboBox1.SelectedItem.ToString();
        //Display all the Particulars
        SqlCeConnection con;
        con = dbConnection();
        SqlCeCommand cmd;
        string sql = "select * from " + pjt;
        try
        {
            cmd = new SqlCeCommand(sql, con);
            SqlCeDataReader rdr = cmd.ExecuteReader();
            int ordName = rdr.GetOrdinal("Name");

            while (rdr.Read())
            {
                string nam = rdr.GetString(ordName);
                gridRow = new RowDefinition();
                gridRow.Height = new GridLength(45);
                DynamicGrid.RowDefinitions.Add(gridRow);

                par = new TextBlock();
                par.Text = nam;
                par.FontSize = 12;
                par.FontWeight = FontWeights.Bold;
                Grid.SetRow(par, i);
                Grid.SetColumn(par, 0);

                amt = new TextBox();
                amt.Height = 20;
                amt.Width = 190;
                amt.Foreground = new SolidColorBrush(Colors.Black);
                Grid.SetRow(amt, i);
                Grid.SetColumn(amt, 1);

                DynamicGrid.Children.Add(par);
                DynamicGrid.Children.Add(amt);
                i++;
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show("Error: " + ex);
        }
        this.Content = DynamicGrid;
    }

我无法弄清楚为什么会发生这种重叠。请帮帮我。

我得到了解决方案。我只是在使用值初始化之前添加了代码来清除网格的子项、行定义和列定义。

这是我使用的代码。

grid1.Children.Clear();
grid1.RowDefinitions.Clear();
grid1.ColumnDefinitions.Clear();

//Adding columns to datagrid
ColumnDefinition gridCol1 = new ColumnDefinition();
ColumnDefinition gridCol2 = new ColumnDefinition();
grid1.ColumnDefinitions.Add(gridCol1);
grid1.ColumnDefinitions.Add(gridCol2);

// Add first column header
TextBlock txtBlock1 = new TextBlock();
txtBlock1.Text = "Particulars";
txtBlock1.FontSize = 14;
txtBlock1.FontWeight = FontWeights.Bold;
txtBlock1.Foreground = new SolidColorBrush(Colors.Green);
txtBlock1.VerticalAlignment = VerticalAlignment.Top;
Grid.SetRow(txtBlock1, 0);
Grid.SetColumn(txtBlock1, 0);

// Add second column header
TextBlock txtBlock2 = new TextBlock();
txtBlock2.Text = "Amount";
txtBlock2.FontSize = 14;
txtBlock2.FontWeight = FontWeights.Bold;
txtBlock2.Foreground = new SolidColorBrush(Colors.Green);
txtBlock2.VerticalAlignment = VerticalAlignment.Top;
Grid.SetRow(txtBlock2, 0);
Grid.SetColumn(txtBlock2, 1);

//// Add column headers to the Grid
grid1.Children.Add(txtBlock1);
grid1.Children.Add(txtBlock2);

RowDefinition gridRow = new RowDefinition();
grid1.RowDefinitions.Add(gridRow);
TextBlock par;
TextBox amt;

int i = 1;
string pjt = comboBox1.SelectedItem.ToString();


//Display all the Particulars
SqlCeConnection con;
con = dbConnection();
SqlCeCommand cmd;
string sql = "select * from " + pjt;
try
{
    cmd = new SqlCeCommand(sql, con);
    SqlCeDataReader rdr = cmd.ExecuteReader();
    int ordName = rdr.GetOrdinal("Name");

    while (rdr.Read())
    {
        string nam = rdr.GetString(ordName);
        gridRow = new RowDefinition();
        gridRow.Height = new GridLength(45);
        grid1.RowDefinitions.Add(gridRow);

        par = new TextBlock();
        par.Text = nam;
        par.FontSize = 12;
        par.FontWeight = FontWeights.Bold;
        Grid.SetRow(par, i);
        Grid.SetColumn(par, 0);

        amt = new TextBox();
        amt.Height = 20;
        amt.Width = 190;
        amt.Foreground = new SolidColorBrush(Colors.Black);
        Grid.SetRow(amt, i);
        Grid.SetColumn(amt, 1);

        grid1.Children.Add(par);
        grid1.Children.Add(amt);
        i++;
    }                   
}
catch (Exception ex)
{
    MessageBox.Show("Error: " + ex);
}

我在 XAML 文件本身中放置了一个网格，而不是动态创建。然后动态添加行和列。谢谢您的帮助。
