</table>
</form>
</body>
</html>
[/php]
This the actual page which use some master page along with this page.
And follwing is the server side code
[php]
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Ajax.Utility.RegisterTypeForAjax(GetType(_Default))
End Sub
<Ajax.AjaxMethod()> _
Public Function GetProductDes(ByVal ProdID As String) As String
Dim CatAdap As New CatagoryTableAdapters.CatagoryTableAdapter
Dim CatTable As Catagory.CatagoryDataTable
Dim ID As Integer = CInt(ProdID.Substring(11).ToString)
CatTable = CatAdap.GetDescription(ID)
If CatTable.Count > 0 Then
Return CatTable(0).Description.ToString
End If
Return Nothing
End Function
[/php]
when i call the GetProductDes function through _default object through javascript i give a runtime error _default undefined
Does anybody have any idea of why the object is the created.
Sorry about the long post.
Thanks guys.
