How to not close a form when user presses enter key inside a text box
c#, devexpress, textbox, winforms
Solution
Update: Try handling the `PreviewKeyDown` event, too. The MSDN documentation explains it pretty well in the Remarks section. By setting `IsInputKey` to true, you can override the default behavior so that your TextBox can handle the key. You'll need to do this in `PreviewKeyDown` and then handle the key as you already do in `KeyDown`.
EDIT: Not working: Previously suggested `EnterMoveNextControl` property
Problem
Having a `TextBox` control (DevExpress `TextEdit` to be precise) inside a WinForms form, I do not want the form to close when the user presses the enter key, if the focus is inside the text box. I thought ``` filterTextBox.KeyDown += (sender, e) => e.Handled = e.KeyCode == Keys.Return || e.KeyCode == Keys.Enter; ``` would be sufficient, but it seems to be ignored and the form still closes. My question is: How to intentionally ignore the enter inside a single line text box control so that the form stays open? Solution The solution of Botz3000 worked for me: ``` filterTextBox.PreviewKeyDown += (sender, e) => e.IsInputKey = e.KeyCode == Keys.Return || e.KeyCode == Keys.Enter; filterTextBox.KeyDown += (sender, e) => e.Handled = e.KeyCode == Keys.Return || e.KeyCode == Keys.Enter; ```
