ASP.Net Vb Public Shared Function Variable

Hi

I'm trying to add a variable to the below code, but every time I do I get an error:

Microsoft JScript runtime error: Sys.Net.WebServiceFailedException: The server method 'GetSlides' failed with the following error: System.InvalidOperationException-- Invalid web service call, missing value for parameter: 'Nodeinfo'.

My code is below can any one help?  (and befor any one asks txtnode.Text does exist)

Thanks

Brasso


<System.Web.Services.WebMethod(), System.Web.Script.Services.ScriptMethod()> _
    Public Shared Function GetSlides(ByVal Nodeinfo As String) As AjaxControlToolkit.Slide()


        Dim imgSlide(3) As AjaxControlToolkit.Slide
       
        imgSlide(0) = New AjaxControlToolkit.Slide("images/Chrysanthemum.jpg", "Autumn", "Autumn Leaves")
        imgSlide(1) = New AjaxControlToolkit.Slide("images/Desert.jpg", "Creek", "Creek")
        imgSlide(2) = New AjaxControlToolkit.Slide("images/Hydrangeas.jpg", "Landscape", "Landscape")
        imgSlide(3) = New AjaxControlToolkit.Slide("images/Jellyfish.jpg", "Dock", "Dock")

        Return (imgSlide)
    End Function

'Call Function

 GetSlides(txtnode.Text)

This appears to be a web method, and it shouldn't be static (Shared)...

The answer is you cant directly.  You have to use Contextkey of you slideshowextender.

e.g.

    <System.Web.Services.WebMethod()> _
      <System.Web.Script.Services.ScriptMethod()> _
    Public Shared Function GetSlides(ByVal contextKey As String) As AjaxControlToolkit.Slide()
then

  SlideShowExtender1.ContextKey = txtnode.Text

to call the function / chage slides

thanks any way
