    Scroll Listview items by text box

    At first I am totally new in VB 2008. In my project I Three textboxes and a listview. I can find the items of listview by 1st textbox change event. The codes are as given below:-

    Code:
    Private Sub sealv_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles sealv.TextChanged
    	        Dim i As Integer
    	        For i = 0 To LV1.Items.Count - 1
    	            LV1.Items(i).BackColor = Color.White
    	        Next
    	        With LV1
    	            lst = .FindItemWithText(sealv.Text, True, 0, True)
    	            If Not lst Is Nothing Then
    	                .Items.Item(lst.Index).EnsureVisible()
    	                .Items.Item(lst.Index).BackColor = Color.YellowGreen
    	            Else
    	                For i = 0 To LV1.Items.Count - 1
    	                    LV1.Items(i).BackColor = Color.White
    	                Next
    	                .Items.Item(0).EnsureVisible()
    	                .Items.Item(0).BackColor = Color.YellowGreen
    	            End If
    	        End With
    	        lst = Nothing
    	    End Sub
    Now, I want to learn the followings:-
    1) How to scroll the listview items by textbox keyDown and KeyUp event.
    2) And I want to get the listview focused item in the 2nd and 3rd textbox by 1st textbox keypress event( Enter press on keyboard).

    Please help me regarding the above.

    By KeyDown and KeyUp I am taking it you mean Up Arrow and Down Arrow?

    You would use the KeyDown Event for this. You would then add code to detect the key(s) you want to do something. You will need to know the KeyCode of the key(s) you want to use. The easy way to get the KeyCode is to place some code in the KeyDown event that displays the KeyCode of the key pressed in a label or msgbox then run the program and hit the keys you will want to use taking note of the keycode shown for each.
    Always use [code][/code] tags when posting code.
