how do that when hit the enter form key board then submit the form

推荐答案

尝试一下:)

try this :)

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
       {
           if (keyData == Keys.Enter)
           {
              //submit logic
           }

           return base.ProcessCmdKey(ref msg, keyData);
       }

您可以设置

You can set AcceptButton[^] property to the button in your Form what handles the data entered.

As SA has pointed out, AcceptButton property makes sense when used with form1.ShowDialog(). And remember, just setting the AcceptButton/CancelButton is not enough. This just tell which button should be invoked on ENTER/ESC. We have to set the DialogResult in the Button handler.

button1.DialogResult = System.Windows.Forms.DialogResult.OK;
button2.DialogResult = System.Windows.Forms.DialogResult.Cancel;

form1.AcceptButton = button1;
form1.CancelButton = button2;

您可以设置form1.KeyPreview = true;并处理事件form1.KeyDown.
将KeyPreview设置为true，则该窗体将在事件传递给具有焦点的控件之前接收键事件

You can set form1.KeyPreview = true; and handle event form1.KeyDown.
Setting KeyPreview to true, then the form will receive key events before the event is passed to the control that has focus

form1.KeyPreview = true;
form1.KeyDown += new System.Windows.Forms.KeyEventHandler(this.form1_KeyDown);

抑制ENTER按钮的方法.

Method to suppress ENTER button.

private void form1_KeyDown(object sender, KeyEventArgs e)
{
  if (e.KeyData == Keys.Enter)
  {
    e.SuppressKeyPress = true; // Event should not be sent to the control
    SaveData(); // Get data in form and save.
  }
}
