WPF is unusually slow to use TextBox in bulk

If you want to be faster, you shouldn't use TextBox.
Please let me know if there is any way to make it faster using TextBox.

c# wpf

The design of 7000 TextBox displayed at the same time is not practical (if so, you should reconsider it), so in common sense, only a small fraction of them are actually displayed on the screen by some kind of scrolling.
For such a design, UI virtualization can reduce the load.In a nutshell, the method is not to actually create elements that are not displayed.
If ItemsSource is specified, ListView and DataGrid have virtualization enabled by default, but

for ItemsControl

<ItemsControl
    VirtualizingPanel.IsVirtualizing="True">
    </ItemsControl.ItemsHost>
        <VirtualizingStackPanel/>
    <ItemsControl.ItemsHost>
</ItemsControl>

and VirtualizingStackPanel for virtualization.If you are using a layout other than StackPanel, you do not have a built-in VirtualizingPanel, so you must make your own.

It is recommended that you analyze it with a profiler once, as it may actually be due to non-UI reasons.
