I am trying to capture TAB keypress on Keydown Event. I can see another post on How to fire an event when the tab key is pressed in a textbox?
However, On the above link, posted solution is not working for me which I mentioned below.
Private Sub TextBox1_KeyDown(sender As Object, e As KeyEventArgs) _
Handles TextBox1.KeyDown
If e.KeyCode = Keys.Tab Then
e.SuppressKeyPress = True
'do something
End If
End Sub
For the testing purpose, I have added 2 simple textboxes on FORM1 and write the below code to capture the TAB on KeyDown event.
Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If e.KeyCode = Keys.Tab Then
e.SuppressKeyPress = True
MsgBox("TAB DOWN")
End If
End Sub
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
Me.Text = e.KeyChar
End Sub
Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp
If e.KeyCode = Keys.Tab Then
MsgBox("TAB UP")
End If
End Sub
Private Sub TextBox1_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Leave
Me.Text = "LEAVE"
End Sub
My above code should suppose to display a message box on KeyDown when TAB is press. It's not working.
Please let me know what I am doing wrong. Thanks in advance!!!
I found a new event called PreviewKeyDown()
Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If e.KeyCode = Keys.Tab Then
Me.Text = "TAB Capture From TextBox1_KeyDown At " & Now.ToString
End If
End Sub
Private Sub TextBox1_PreviewKeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles TextBox1.PreviewKeyDown
If e.KeyCode = Keys.Tab Then
Me.Text = "TAB Capture From TextBox1_PreviewKeyDown At " & Now.ToString
End If
End Sub
If you will execute the above code, you will able to capture TAB key on PreviewKeyDown() event.
