+<h1>TPager Sample</h1>

+<p>

+The following sample displays three different pagers associated with a single TDataList control. The datalist control is enabled with custom paging, which allows it to read only one page of data each time. This is typical in DB-driven applications.

+</p>

+

+<div>

+Go to page: 

+<com:TPager ID="Pager" 

+	ControlToPaginate="DataList" 

+	PageButtonCount="3"

+	Mode="Numeric"

+	OnPageIndexChanged="pageChanged"

+	/>

+</div>

+

+<com:TDataList

+     ID="DataList"

+     AllowPaging="true"

+     AllowCustomPaging="true"

+	 PageSize="2"

+     EnableViewState="true"

+     RepeatColumns="2"

+     RepeatDirection="Vertical"

+     ItemStyle.Font.Italic="true"

+     ItemStyle.BackColor="#BFCFFF"

+     HeaderStyle.BackColor="black"

+     HeaderStyle.ForeColor="white"

+     FooterStyle.BackColor="gray"

+     AlternatingItemStyle.BackColor="#E6ECFF">

+

+<prop:HeaderTemplate>

+<div style="font-weight:bold; text-align:center;">Computer Parts</div>

+</prop:HeaderTemplate>

+

+<prop:FooterTemplate>

+<div style="font-weight:bold; text-align:center;">

+Total <%# $this->Parent->PageCount %> pages.

+</div>

+</prop:FooterTemplate>

+

+<prop:ItemTemplate>

+<table border="0" width="300">

+<tr>

+  <th>ID</th><th>Name</th><th>Quantity</th><th>Price</th>

+</tr>

+<tr>

+  <td align="right"><com:TLiteral Text=<%#$this->DataItem['id'] %> /></td>

+  <td align="right"><com:TLiteral Text=<%#$this->DataItem['name'] %> /></td>

+  <td align="right"><com:TLiteral Text=<%#$this->DataItem['quantity'] %> /></td>

+  <td align="right">$<com:TLiteral Text=<%#$this->DataItem['price'] %> /></td>

+</tr>

+</table>

+</prop:ItemTemplate>

+

+</com:TDataList>

+

+<com:TPager ID="Pager2" 

+	ControlToPaginate="DataList" 

+	FirstPageText="9"

+	LastPageText=":"

+	Mode="NextPrev"

+	NextPageText="4"

+	PrevPageText="3"

+	Font.Name="Webdings"

+	OnPageIndexChanged="pageChanged"
