Question

I have a WinForms application which uses a list box to display list of items. My application hangs whent the number of items in the listbox exceeds some 150 items. Is this the property of ListBox control that it can hold only so many items? If so, I would request you to provide a solution to this problem.

Thanks,
Rakesh.

It all depends on what you are binding, if you are binding simple key value pairs you can instantly bind 10k easy. You might want to try adding the items in a loop instead of binding to see if there is a certain item it hangs on.

for (int i = 0; i < 10000; i++)
{
     listBox1.Items.Add("item:" + i.ToString());
}
