<Button Content="Add Hrzntly" Grid.Row="0" Grid.Column="1" Width="100" Height="30" Click="Button_Click"/>
    <Button Content="Add Vrtcly" Grid.Row="1" Grid.Column="0" Width="100" Height="30" Click="Button_Click_1"/>
    <Grid ShowGridLines="True" x:Name="gridChart" Grid.Row="1" Grid.Column="1">
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
    </Grid>


    private void Button_Click(object sender, RoutedEventArgs e)
    {
        var newTextBox = new TextBox();
        newTextBox.Width = 100;
        newTextBox.Height = 30;
        newTextBox.Text = "FTB solutions";
        // here set new textbox parameters
        gridChart.Children.Add(newTextBox);

    }

    private void Button_Click_1(object sender, RoutedEventArgs e)
    {
        var newTextBox = new TextBlock();
        newTextBox.Width = 100;
        newTextBox.Height = 30;
        newTextBox.Text = "FTB solutions";
        // here set new textbox parameters
        gridChart.Children.Add(newTextBox);
    }

Answer 1

您需要指定TextBox正在进行哪一Row 。

newTextBox.SetValue(Grid.RowProperty, number);

Answer 2

Is to to create a list? if so, there are already built in controls within WPF that support this (no need to re-invent).

Example

xaml:

<ListBox x:Name="myListBox Width="200" Margin="10"/>

xaml.cs:

private void Button_Click_1(object sender, RoutedEventArgs e)
{
    var listBoxItem = new ListBoxItem();
    listBoxItem.Content = "this is a new item";
    myListBox.Items.Add(listBoxItem);
}

Though, handling events like this is a bit more 'Winform-ish'. With WPF, you would want to use MVVM, and handle the adding/updating of collections via a ViewModel (rather than code behind). Please look into MVVM once you have gained more experience with WPF.

For reference, see: How can I add items from a listbox to a list by clicking a button without any codebehind?
