I'm creating a page that uses Linqfor data access and I'm using DataList to display data. How can I use Linq to do data paging ? Please read simple code below :
I normally use a PagedDatasource but this only seems to work with a DataTable.
Here's my Linq to return Datatable which is bound with Datalist :
Public Shared Function GetStudentList() As DataTable
Dim db As New DemoDataClassesDataContext()
Dim query = From st In db.students _
Order By st.st_studentid Ascending _
Select st
Dim dtStudent = New DataTable("myst")
dtStudent.Columns.Add("st_id", GetType(Integer))
dtStudent.Columns.Add("st_userid", GetType(Guid))
dtStudent.Columns.Add("st_studentid", GetType(Integer))
dtStudent.Columns.Add("st_firstname", GetType(String))
dtStudent.Columns.Add("st_lastname", GetType(String))
dtStudent.Columns.Add("st_gender", GetType(String))
dtStudent.Columns.Add("st_email", GetType(String))
For Each q In query
dtStudent.Rows.Add(New Object() {q.st_id, q.st_userid, q.st_studentid, q.st_firstname, q.st_lastname, q.st_gender, q.st_email})
Next
Return dtStudent
End Function
In the code behind of the page :
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack() Then
LoadData()
End If
End Sub
Private Sub LoadData()
dsStduent = da_Student.GetStudentList()
dt_Student.DataSource = dsStduent
dt_Student.DataBind()
End Sub
