Do not allow Enter Key to make a new line in MultiLine TextBox C#

I set the property Multiline=true;.

I do not want to allow the Enter Key to make a new line.

How can I solve this issue?

Well, I am quite late to the party, but for others who read this I would mention that there is a property named TextBox.AcceptsReturn (Boolean).

Just set it in the properties window of the TextBox.

I had the same problem just the other way round: I had a multiline TextBox, but it didn't allow me to enter Returns.

That could be as simple as listening to TextChanged event and then executing the following line inside it:

txtYourTextBox.Text = txtYourTextBox.Text.Replace(Environment.NewLine, "");

This solution involves some screen flicker though. A better way is to prevent it entirely by listening to KeyDown event:

private void txtYourTextBox_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
        e.SuppressKeyPress=true;
}
