When you add a
ToolStripComboBox control to a Microsoft Windows
Application project that uses the Microsoft .NET Framework 2.0, you cannot control the behavior that occurs when a user presses ENTER.
Back to the top
This problem occurs because the
ToolStripComboBox and
ComboBox controls do not contain an
AcceptsReturn property that you can use to control ENTER key behavior.

To work around this problem, use one of the following methods:
| • | Add a KeyUp event handler to the ToolStripComboBox control. To do this, use code that resembles the following code example.private void toolStripComboBox1_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyData == Keys.Enter)
{
MessageBox.Show("ENTER");
};
} |
| • | Create a custom ToolStripComboBox control that encapsulates a
custom ComboBox control. In this custom ComboBox control, override the IsInputKey method to
capture the ENTER key. To do this, use code that resembles the following code example.protected override bool IsInputKey(System.Windows.Forms.Keys keyData)
{
if(keyData == Keys.Enter){
return true;
}else{
return false;
}
} |
