Hi Experts

in my  textbox1  presskey i have the following code

      If e.KeyChar <> "" Then

            Dim dv As New DataView
            Dim regicx As String = ""
            If e.KeyChar < "A" Or e.KeyChar > "z" And e.KeyChar <> ControlChars.Back Then
                If Microsoft.VisualBasic.Len(codeBox.Text.Trim) > 0 Then
                    regicx = Microsoft.VisualBasic.Left(codeBox.Text, Microsoft.VisualBasic.Len(codeBox.Text.Trim) - 1)
                End If
            Else
                regicx = codeBox.Text.Trim + e.KeyChar.ToString
            End If
            Dim reglenx = Microsoft.VisualBasic.Len(regicx)
            dv = New DataView(dtCustFull, "Substring(ccode, 1, " & reglenx & ")= '" & regicx & "'", "", DataViewRowState.CurrentRows)
            DataGridView2.DataSource = dv
            DataGridView2.Visible = True
        Else
            DataGridView2.Visible = False
        End If

and then textbox1 keydown
  DataGridView2.Visible = False

But   DataGridView2 is still visible

I have even tried in the next textbox.gotfocus
  DataGridView2.Visible = False

still same problem

I tried this code in myform.click
  DataGridView2.Visible = False

and when I click on my form it disappears.

Please help

            DataGridView2.Visible = False
        End If

Considering it's a keyPress I don't think e.KeyChar will ever be blank.

Did you confirm the textbox.GotFocus actually fires?

Try the Enter Event.
