How to send TAB keypress programmatically to netcf
I need my edit box to work the same for both tabs and enter key.
I found many problems related to this in the app. Is there a way I can send the tab key to the form / edit field.
(Note that this must be in the Compact Framework.)
Solution:
Here's what I ended up using:
// This class allows us to send a tab key when the the enter key is pressed for the mooseworks mask control.
public class MaskKeyControl : MaskedEdit
{
[DllImport("coredll.dll", EntryPoint = "keybd_event", SetLastError = true)]
internal static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
public const Int32 VK_TAB = 0x09;
protected override void OnKeyDown(KeyEventArgs e)
{
if (e.KeyData == Keys.Enter)
{
keybd_event(VK_TAB, VK_TAB, 0, 0);
return;
}
base.OnKeyDown(e);
}
protected override void OnKeyPress(KeyPressEventArgs e)
{
if (e.KeyChar == '\r')
e.Handled = true;
base.OnKeyPress(e);
}
}
I give the answer to Hans because his code made me move towards the right solution.

You can try this control:
using System;
using System.Windows.Forms;
class MyTextBox : TextBox {
protected override void OnKeyDown(KeyEventArgs e) {
if (e.KeyData == Keys.Enter) {
(this.Parent as ContainerControl).SelectNextControl(this, true, true, true, true);
return;
}
base.OnKeyDown(e);
}
protected override void OnKeyPress(KeyPressEventArgs e) {
if (e.KeyChar == '\r') e.Handled = true;
base.OnKeyPress(e);
}
}
