Windows窗体用户控制的问题

Question

I am creating a Windows forms user control. This control has a textbox and a listbox .

When the end user types text in the textbox , the listbox will appear and filter the data depending on the text box. The data is set by a datasource.

I have created this control because I want to filter in the contains of data "not start with."

Now after I create the control I found a problem when the list appear it did not appear out of form boundaries.

I change the control size in appear and disappear the listbox. What can I do?

Answer 1

You can not show a ListBox out of the boundaries of its parent Form . What you really wan to do is open a new Form where ListBox is visible.

Hope this helps.
