Hi All
I am an absolute starter in VB.net

I am trying to enter data into a combo box and want to trigger a sub routine once I press return.
I tried this:
Private Sub ComboBox1_TextChanged(sender As Object, e As EventArgs) Handles ComboBox1.TextChanged
but this triggers on the first letter typed.
ie If I want to enter "John Doe" the sub routine starts as soon as I enter the "J"
Can anyone point me in the right direction.

Thanks given in advance

Solution 1

Use the

Combobox1_KeyDown

event.

Here's some code to start:

VB

If e.KeyCode = Keys.Enter Then
          'call your sub here
      End If

Thank you for your suggestion. I have modified my code as follows;

VB

Private Sub Player1_KeyDown(sender As Object, e As EventArgs) Handles Player1.KeyDown
        'set curComboItem to the text contained within the ComboBox
        Dim curComboItem = Player1.Text.ToString()
        'set curCombo to name of combobox
        Dim curCombo = Player1
        'check to see if last keystroke was the enter key if so run sub routine
        If e.KeyCode = Keys.Enter Then
            ComboBox_Update(curComboItem, curCombo)
        End If
    End Sub

but I get a code error of "KeyCode is not a member of 'System.EventArgs' against e.KeyCode

Can you help?

Thanks

PS Just set the arguement from "e as EventArgs" to "e as KeyEventsArgs" error cleared.

Thank you very much for your support the solution works well.
