Keypress event in vb.net

[bhagawatshinde]

Hi,
I am developing an windows application in vb.net.
in this project i want to set the Richtextbox height according to the content in that richtextbox. For this i want to call the Richtextbox textchanged event on button click

Here is my code but i got error

on button click

 RichAll_KeyPress(sender, New KeyPressEventArgs(e))

and

 Private Sub RichAll_KeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs)
        Dim tempFont As Font = DirectCast(sender, RichTextBox).Font

        Dim textLength As Integer = DirectCast(sender, RichTextBox).Text.Length

        Dim textLines As Integer = DirectCast(sender,    RichTextBox).GetLineFromCharIndex         (textLength) + 1

        Dim Margin As Integer = DirectCast(sender, RichTextBox).Bounds.Height - DirectCast(sender, RichTextBox).ClientSize.Height

        DirectCast(sender, RichTextBox).Height = (TextRenderer.MeasureText(" ", tempFont).Height * textLines) + Margin + 2

 End Sub

How i can solve the issue
can i call textchanged event

Thanks in advance...
