I am using the autocomplete control with a single line textbox.
The problem I am facing is that, when I type something in the textbox, the autocomplete popup is displayed below the textbox, but when i try to scroll through the autocomplete items using mouse wheel, the parent form gets scrolled. And due to this the position of the textbox changes but the autocomplete popup remains at the same position.
Please let me know how I can handle this issue.

Hi Pradnya,

The issue 'When try to scroll through the suggestions in the popup using Mouse Wheel, the main form scrolls first and auto complete popup remains at the same position' can be resolved by the workaround below.


void textBox1_MouseWheel(object sender, MouseEventArgs e)
if (this.autoComplete1.IsDropDownShowing())

((HandledMouseEventArgs)e).Handled = true;


Please let me know if this helps you.
