The paging function of Microsoft DataPager is very powerful. Do not set database stored procedures. You only need to add a DataPager control and associate it with the control to be paged. A simple setting can have a good paging effect. Of course, the ideal results should be processed at the front-end and back-end.

DataPager display mode in winform:

Styles in webForm are controlled by TemplatePagerField, NextPreviousPagerField, and NumericPagerField.

By setting the cooperation of the preceding controls, you can also achieve the effect of winForm. The most important of the three controls is the TemplatePagerField control.

The following describes how to set the TemplatePagerField control:

Copy codeThe Code is as follows:
<% @ Page language = "VB" %>
<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN"
Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd>
<Script runat = "server">
Protected Sub TemplatePagerField_OnPagerCommand (ByVal sender As Object ,_
ByVal e As DataPagerCommandEventArgs)
'Check which button raised the event
Select Case e. CommandName
Case "Next"
Dim newIndex As Integer = e. Item. Pager. StartRowIndex + e. Item. Pager. PageSize
If newIndex <= e. TotalRowCount Then
E. NewStartRowIndex = newIndex
E. NewMaximumRows = e. Item. Pager. MaximumRows
End If
Case "Previous"
E. NewStartRowIndex = e. Item. Pager. StartRowIndex-e. Item. Pager. PageSize
E. NewMaximumRows = e. Item. Pager. MaximumRows
Case "First"
E. NewStartRowIndex = 0
E. NewMaximumRows = e. Item. Pager. MaximumRows
End Select
End Sub
