It was just a standalone desktop program for each computer (1 user).Īm I wrong or are these Windows not packed with controls:Īt least way more than the 100+ that is supposedly some point where it's time to scale back:Īre they images that turn into controls when the mouse scrolls over them? How many users were there? Painting an area of the screen to look like a control takes very little resources.

Both controls can be used in a so called virtual mode, which allowsįor manual control of the data source display. The other, more sofisticated way is to use a DataRepeaterControl. One way to display large quantity of Excel-like data in Windows Forms is to use a DataGridView control. It may have been a Java application, I'm not sure if that would make a I'd say at any given moment there were 2500 interactive buttons and interactive cells of information.

Hi RBBB2, Well, when I was working at a financial firm we used an trading application by ThinkorSwim It may have been a Java application, I'm not sure if that would make a difference.
In addition, you could click on the prices as they were coming in and it would automatically open more forms upon clicking on the prices, not to mention Each order had a button to "Cancel", and "Modify".

I see professional Windows programs with tons of controls that operate without any issues. Caching can also be used, so instead of destroying the control's window when you don't need it any more, you could reinitialize it, make it invisible and bring it back into view at the desired position some With the current cell object and displayed.

No, there are only a very few. Hi RBBB2, Isn't an Excel sheet a similar set of textbox controls. Somehow programmers are finding a way to make it work. How does Excel manage 10s of thousands of boxes of information without any delay, but 1000 blank textboxes is too much on a Windows form? I also just copied and pasted 1000īuttons onto an Excel sheet and there is no delay in scrolling around the sheet.Ģ) What should I do if eliminating the controls isn't an option?

Just to experiment and make sure that it wasn't something in my code that was causing the slowdown, I created a form and just copied about 1000 blank textboxes, making the window look like a spreadsheet. It appears that 1300 is a lot for the system to handle.
I've looked around the forums and the web at similar questions and it seems that the most common response is to cut back on the number of controls. I have a form I made with Visual Studio with about 1300 controls (mostly textboxes) that moves very slow.
