[RESOLVED] [2008] Multiline Textbox and KeyDown Event

Hi!!

I have two Multilined textboxes on my form (Textbox1 and Textbox2). Then I have this code:

Code:

---

    Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
        If e.KeyCode = Keys.Right Then TextBox2.Focus()
        If e.KeyCode = Keys.Down Then TextBox2.Focus()
    End Sub

---

I run the project I select the textbox1 and click the right arrow key, and he selects the textbox2 as it would be expected. Now the problem is: if I click in the down arrow key while selecting the textbox1, the textbox2 should get selected, but it doesnt. Why?

Thks a lot!

Works fine for me. That said, your code should be:

vb.net Code:

If e.KeyCode = Keys.Right OrElse e.KeyCode = Keys.Down Then TextBox2.Select()

or:

vb.net Code:

Select Case e.KeyCode
    Case Keys.Right, Keys.Down
        TextBox2.Select()
End Select

You should not have two separate If blocks and you should not be calling Focus.

Well It only works If I press right, because if I press down it doesnt work.
I've tried with a textbox where Multiline=False and it worked wonderfully. So I think its related to the multiline.

I see what you mean. I overlooked the Multiline part. Sorry about that. Change the code to this and it will work:

vb.net Code:

Select Case e.KeyCode
    Case Keys.Right, Keys.Down
        TextBox2.Select()
        e.SuppressKeyPress = True
End Select

Why exactly that should be, I don't know, because the arrow keys don't raise KeyPress events anyway. Seems like a bit of a bug but it's not worth worrying about with such a simple workaround.

Code:

and you should not be calling Focus.

Just out of curiosity why should I call Select instead of Focus?

THKS a loot for the last code. Just a pro like you could know something like that, cause the solution "doesnt follow logic".

PS: I didnt rate you because I couldn't - "You must spread some Reputation around before giving it to jmcilhinney again."

From the MSDN documentation for the Control.Focus method:

I don't do it for the reputation. I do it for the money. You did put a cheque in the mail, right? ;)

Must be arriving any minute now
