I have a user control on my web form which is as follows in the following link..
http://s8.postimg.org/dmcydrv3p/sample.png[^]

I select the program year, category type , category and position group and then click search, it should return a collection which contains the programyearID, categorytypeID and positionGroupID for the corresponding selected items in the dropdownlist and pass it on to a webmethod which is already defined to get a specific certificationID.

Interface
VB
Namespace SI.Certification.UserControl

Public Interface IUserSearchResultList
Property DataSource() As User.Learning.Business.HR.UserCollection
ReadOnly Property List() As User.Web.UI.WebControls.PagedRepeater
End Interface 
End Namespace

VB
Public Class curriculum_search
    Inherits System.Web.UI.UserControl

            Return _dataSource
        End Get
        Set(value As UserCollection)

This is the webmethod I have to use in my usercontrol to pass the parameters

VB
_ Public Function GetCertificationLevelsList(ByVal programYearId As Integer, ByVal PositionGroupId As String, ByVal CategoryId As String) As User.Department.Application.Curriculum.Items Dim items As User.Department.Application.Curriculum.Items = User.Department.Application.Curriculum.CategoryCollection.GetCategoryLevelsList(programYearId, PositionGroupId, CategoryId) items.Sort() Return items End Function


I am stuck here, pls help to proceed further. Thanks

How to pass the ID's to the webmethod?
Apart from using the [WebMehtod] attribute mark the method as static.
