Class PageControlBase

Namespace: EPiServer.Web.WebControls

Assembly: EPiServer.Cms.AspNet.dll

Syntax

public abstract class PageControlBase : Control, IEnumerable, IPageSource, INotifyPropertyChanged, IPageControl

Remarks

Examples

  Simple example showing how data is read and displayed on a page. 
  The PageLink specifies which page the list will be retrieved from.

    <episerver:PageList MaxCount="1" PageLink="<%#CurrentPage.PageLink%>" runat="server" ID="PageList2">
<ItemTemplate>
<episerver:property PropertyName="PageName" runat="server"/>
<br/>
</ItemTemplate>
</episerver:PageList>

        Illustrates how data from one control can be used by several other controls, in this
        example it is only PageList1 that delivers data and the others are only used for presentation.

    <episerver:PageList PageLink="<%#CurrentPage.PageLink%>" runat="server" ID="PageList1"/>

<episerver:PageList MaxCount="1" DataSource="<%#PageList1%>" runat="server" ID="PageList3">
<ItemTemplate>
<episerver:property ID="Property1" PropertyName="PageName" runat="server"/>
<br/>
</ItemTemplate>
</episerver:PageList>

<episerver:PageList MaxCount="2" SkipCount="1" DataSource="<%#PageList1%>" runat="server" ID="PageList4">
<ItemTemplate>
<episerver:property ID="Property2" PropertyName="PageName" runat="server"/>
<br/>
</ItemTemplate>
</episerver:PageList>

<asp:Repeater DataSource="<%#PageList1%>" runat="server" ID="Repeater1">
<ItemTemplate>
<%#DataBinder.Eval(Container.DataItem,"PageName")%>
<br/>
</ItemTemplate>
</asp:Repeater>

Examples

This example shows how to assign a value to the PageLink property of the PageTree control through code. This code is a modified version of the UserControl prefix.ascx.cs code-behind file in the EPiServer sample site.

We cannot assign to the PageLink property in the Page_Load event as it will be to late for the control to see it. Instead we use the Control.Init event.

        private void Page_Init(object sender, System.EventArgs e)
{
    // Set the tree to start at the site start page
    PageDataTree.PageLink = EPiServer.Core.PageReference.StartPage;
}
private void Page_Load(object sender, System.EventArgs e)
{
//if (((EPiServer.PageBase)Page).CurrentPage["ListingContainer"] == null)
//    MainBodyWidth = 410 + 170;
// This is too late, we need to change the PageLink property in the Page_Init method
// Pagedatatree1.PageLink = ((EPiServer.PageBase)Page).Configuration.StartPage;
}
private void InitializeComponent()
{
this.Load += new System.EventHandler(this.Page_Load);
this.Init += new System.EventHandler(this.Page_Init);
}
