Question

I have a program that loads a tab that has roughly 332 text boxes it loads. When loading a new tab there is a 2-3 second delay before the tab can be displayed. I have tried to suspend and resume and even looked into threading but found out that a winform can only use one thread.

I was wondering if there was a way to create the text boxes in another thread and then add them into the main form or a way to better create 332 text boxes.

thanks for your help.

Depending on your layout, I’d strongly recommend replacing the textboxes with a DataGridView, or otherwise loading the textboxes on scroll with some kind of continous-control .
The main bottle neck is the creation of handles. In winforms, each control gets its own handle (even labels), and when used in large numbers such as this, can indeed give performance problems.

If a datagridview is not an option, can you give some more information on the layout (a screenshot perhaps?), so the community can have a go at alternatives. Creating the textboxes in another thread will create problems when you try to add them, but you could create them only when needed.
