Objectives

Learn how to sort columns in a grid in both ascending and descending order

Learn how to use automatic and custom paging

Learn how to use templated columns

Pagination

11


Webinar Series 2003

Sorting Grids

Steps to provide sorting

1. AllowSorting = “True”

2. Provide sorting event handler that retrieves sort expression (name of sort column)

3. Sort data based on sort expression

12


Webinar Series 2003

Simple Sort Example: SortedGrid1.aspx

Private Sub dgrCustomers_SortCommand(source As Object, _e As DataGridSortCommandEventArgs) Call BindDataGrid(e.SortExpression)

End Sub

Sub BindDataGrid(ByVal strSort As String)...

' Customize sort order based on strSortDim strSQL As String = _"SELECT CustomerID, CompanyName, ContactName, " & _"Country FROM Customers " & _"ORDER BY " & strSort

...

Private Sub dgrCustomers_SortCommand(source As Object, _e As DataGridSortCommandEventArgs) Call BindDataGrid(e.SortExpression)

End Sub

Sub BindDataGrid(ByVal strSort As String)...

' Customize sort order based on strSortDim strSQL As String = _"SELECT CustomerID, CompanyName, ContactName, " & _"Country FROM Customers " & _"ORDER BY " & strSort

...

13


Webinar Series 2003

Ascending/Descending Sorts

Need to store away sort column and direction between postbacks

Use ViewState

14


Webinar Series 2003

Ascending/Descending Sort ExampleSortedGrid2.aspx – rebuilds DataReader each time

Private Sub dgrCustomers_SortCommand(…) If ViewState("SortCol") = e.SortExpression Then

If ViewState("SortDir") = "ASC" ThenViewState("SortDir") = "DESC"

ElseViewState("SortDir") = "ASC"

End IfElse

ViewState("SortDir") = "ASC"End IfViewState("SortCol") = e.SortExpressionCall BindDataGrid()

End SubSub BindDataGrid()

…Dim strSQL As String = _

"SELECT CustomerID, CompanyName, ContactName, " & _"Country FROM Customers "

If Not ViewState("SortCol") Is Nothing ThenstrSQL &= "ORDER BY " & ViewState("SortCol") & " " & _ViewState("SortDir")

End If...




End IfElse

ViewState("SortDir") = "ASC"End IfViewState("SortCol") = e.SortExpressionCall BindDataGrid()

End SubSub BindDataGrid()

…Dim strSQL As String = _

"SELECT CustomerID, CompanyName, ContactName, " & _"Country FROM Customers "

If Not ViewState("SortCol") Is Nothing ThenstrSQL &= "ORDER BY " & ViewState("SortCol") & " " & _ViewState("SortDir")

End If...

15


Webinar Series 2003

Ascending/Descending Sort ExampleSortedGrid3.aspx – caches DataView in Session




End IfElse

ViewState("SortDir") = "ASC"End IfViewState("SortCol") = e.SortExpression

CType(Session("dvCustomer"), DataView).Sort = _ViewState("SortCol") & " " & ViewState("SortDir")

Call BindDataGrid()End Sub




End IfElse

ViewState("SortDir") = "ASC"End IfViewState("SortCol") = e.SortExpression

CType(Session("dvCustomer"), DataView).Sort = _ViewState("SortCol") & " " & ViewState("SortDir")

Call BindDataGrid()End Sub

Webinar Series 2003

Pagination

Properties related to pagination

AllowPaging

AllowCustomPaging

PageSize

PagerStyle-Mode (NextPrev or NumericPages)

PagerStyle-Position (Top, Bottom, TopAndBottom)

PagerStyle-PageButtonCount

…

18


Webinar Series 2003

Automatic Pagination

AllowPaging = "True"

You provide DataGrid with data source and a PageSize and it takes care of chopping up data into pages and displaying the correct page

Very little coding on your part

Requires query to be re-run for every page unless you cache the data source somewhere

19


Webinar Series 2003

Pagination ExamplesCustomersPageAuto1.aspx – rebuilds DataReader each timeCustomersPageAuto2.aspx – caches DataSet in Session

<asp:DataGrid id="dgrCustomers" runat="server"...AllowPaging="True"PageSize="10"PagerStyle-Mode="NumericPages"PagerStyle-HorizontalAlign="Left">

</asp:DataGrid>

Private Sub dgrCustomers_PageIndexChanged(source As Object, _e As DataGridPageChangedEventArgs) dgrCustomers.CurrentPageIndex = e.NewPageIndexCall BindDataGrid()

End Sub

<asp:DataGrid id="dgrCustomers" runat="server"...AllowPaging="True"PageSize="10"PagerStyle-Mode="NumericPages"PagerStyle-HorizontalAlign="Left">

</asp:DataGrid>

Private Sub dgrCustomers_PageIndexChanged(source As Object, _e As DataGridPageChangedEventArgs) dgrCustomers.CurrentPageIndex = e.NewPageIndexCall BindDataGrid()

End Sub

20


Webinar Series 2003

Custom Pagination

AllowPaging = "True"

AllowCustomPaging = "True"

You provide DataGrid with each page of data

More coding than automatic paging

21


Webinar Series 2003

Custom Pagination, Solution #1

How do you split up data into pages and grab correct page?

Solution #1: Use arbitrarily-divided evenly-sized pages

Use db-specific SQL (temp tables, cursors, etc.)

Example:

CustomersPageCustom1.aspx

Uses procGetCustomersPage stored proc & SQL Server temp tables

22


Webinar Series 2003

Arbitrarily-Divided Pages ExampleCustomersPageCustom1.aspx – code

Function GetPage(intPageSize As Integer, intPageIndex As Integer) As SqlDataReaderDim strCnx As String = "server=localhost;uid=sa;pwd=;database=northwind;"Dim prm As SqlParameter

Dim cnx As SqlConnection = New SqlConnection(strCnx)cnx.Open()

Dim cmd As SqlCommand = New SqlCommand("procGetCustomersPage", cnx)cmd.CommandType = CommandType.StoredProcedure

' Create parameters…

Dim sdr As SqlDataReadersdr = cmd.ExecuteReader(CommandBehavior.CloseConnection)

Return sdrEnd Function

Private Sub dgrCustomers_PageIndexChanged(source As Object, e As DataGridPageChangedEventArgs)dgrCustomers.CurrentPageIndex = e.NewPageIndexdgrCustomers.DataSource = GetPage(dgrCustomers.PageSize, e.NewPageIndex)dgrCustomers.DataBind()

End Sub







Private Sub dgrCustomers_PageIndexChanged(source As Object, e As DataGridPageChangedEventArgs)dgrCustomers.CurrentPageIndex = e.NewPageIndexdgrCustomers.DataSource = GetPage(dgrCustomers.PageSize, e.NewPageIndex)dgrCustomers.DataBind()

End SubView

26


Webinar Series 2003

Custom Pagination, Solution #2

How do you split up data into pages and grab correct page?

Solution #2: Use data-dependent unevenly-sized pages

Use an existing column to split up pages

Example:

CustomersPageCustom2.aspx

Uses CompanyName LIKE "A*" expression

Requires use of ItemCreated event handler to fix up pager

27

Data-Dependent Pages ExampleCustomersPageCustom2.aspx – code 1 of 2

Template Columns

Webinar Series 2003

When to Use Template Column?

If you need to do something that is not provided by standard DataGrid columns

Problem: Need to link to another page but querystring may contain special characters

Try using CustomerMain.aspx with Netscape and a CustomerId containing a space

Solution: Use TemplateColumn that calls Server.UrlEncode to encode querystring

CustomerMain_Template.aspx

31


Webinar Series 2003

TemplateColumn Example – Encoding querystringCustomerMain_Template.aspx

<asp:TemplateColumn HeaderText="Customer"><itemtemplate>

<asp:LabelText='<%# CreateLinkCol(Container.DataItem("CustomerId"),

Container.DataItem("CompanyName")) %>' runat="server"/>

</ItemTemplate></asp:TemplateColumn>

<asp:TemplateColumn HeaderText="Customer"><itemtemplate>

<asp:LabelText='<%# CreateLinkCol(Container.DataItem("CustomerId"),

Container.DataItem("CompanyName")) %>' runat="server"/>

</ItemTemplate></asp:TemplateColumn>

Function CreateLinkCol(ByVal strId, ByVal strName) As String' Create hyperlink with encoded querystring' to handle special chars in IdReturn "<a href=""CustomerEdit_TemplateCol.aspx?Customer=" & _Server.UrlEncode(strId) & """>" & strName & "</a>"

End Function

Function CreateLinkCol(ByVal strId, ByVal strName) As String' Create hyperlink with encoded querystring' to handle special chars in IdReturn "<a href=""CustomerEdit_TemplateCol.aspx?Customer=" & _Server.UrlEncode(strId) & """>" & strName & "</a>"

End Function

32


Webinar Series 2003

When to Use Template Column?

If you need to do something that is not provided by standard DataGrid columns

Problem: Would like user to be able to use a dropdownlist control when editing within a grid

Solution: Use TemplateColumn

DataGridWithDropDown.aspx
