Radio Buttons Question

Hello Jing,
  I want to know, if have a radio button in different cells will it still act the same as it was in the same cell? Why i am asking is because of layout reason. I have as label boxes now i want to have in spreadsheet format. Also, another things is can change the way the radio button looks like because i change the way it looks with an image.

Update:
I see from the documentation you create a radiogroup and make that radio button part of the radiogroup and it will function as one selection even though it is in different cells?

Re: Radio Buttons Question

Yes a RadioGroup can make all radio cells in the group toggling other else. What is your problem?

Re: Radio Buttons Question

Hello Jing,
   What i wanted to know is can I change the way the radio paint event to show different button image? After i posted it seen you could put the radio button in different cells, per your example you had them in one cell.. that was real question was, but i need know if can do this with the radio bottons. That is code i have radio control now. what i am trying to is get rid of all my label boxes and textboxes on the form and replace them with your spreadsheet grid.

shane

do something like this:

  Private Sub radLinear_Paint(sender As Object, e As PaintEventArgs) Handles radLinear.Paint
        RadioChange(sender, e)
    End Sub

      Private Sub RadioChange(sender As Object, e As PaintEventArgs)
        If DirectCast(sender, RadioButton).Checked Then
            e.Graphics.DrawImageUnscaled((My.Resources.TranspartSelectedRadioButton), 0, 0)
        Else
            e.Graphics.DrawImageUnscaled((My.Resources.TranspartUnselectedRadioButton), 0, 0)
        End If
    End Sub

Re: Radio Buttons Question

To do owner drawing by overriding the OnPaint method, there is an example code that contains a class derived from the RadioButtonCell class.

VB.NET:

Class ImageRadioButtonCell
  Inherits RadioButtonCell

  Public Overrides Sub OnPaint(dc As RGDrawingContext)
    If MyBase.ButtonState = Windows.Forms.ButtonState.Checked Then
      dc.Graphics.DrawImageUnscaled(My.Resources.apple, MyBase.Bounds.Location)
    Else
      dc.Graphics.DrawImageUnscaled(My.Resources.banana, MyBase.Bounds.Location)
    End If
  End Sub

End Class

The following code adds the customize radio button cells onto worksheet:

Dim rg As New RadioButtonGroup
sheet("B1") = New Object() {New ImageRadioButtonCell With {.RadioGroup = rg}, "Radio 1"}
sheet("B2") = New Object() {New ImageRadioButtonCell With {.RadioGroup = rg}, "Radio 2"}
sheet("B3") = New Object() {New ImageRadioButtonCell With {.RadioGroup = rg}, "Radio 3"}

Hope this helps.

Re: Radio Buttons Question

Hello Jing,
  That does help.. I did not think you could inherit radiobuttoncell object from the control.
Thank you,
Shane
