Cleaning up the List Widget Template
Alright,
Here is my issue. I'm trying to create a simple list template that just prints out the content for each list item. It works fine - but there seems to be a lot of unnecessary code that is added to the source. See below:
<input id="ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl_ctrl0_listItemsControl_ClientState" name="ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl_ctrl0_listItemsControl_ClientState" type="hidden" /><span id="ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl_ctrl0_listItemsControl" style="display:none;"></span> <input id="ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl_ClientState" name="ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl_ClientState" type="hidden" /><span id="ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl" style="display:none;"></span> <span></span>Sys.Application.add_init(function() $create(Telerik.Web.UI.RadListView, "UniqueID":"ctl00$Cycle$C001$ctl00$ctl00$ctl00$listsControl$ctrl0$listItemsControl","_clientSettings":,"_currentPageIndex":0,"_pageCount":1,"_pageSize":10,"clientStateFieldID":"ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl_ctrl0_listItemsControl_ClientState", null, null, $get("ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl_ctrl0_listItemsControl")););Sys.Application.add_init(function() $create(Telerik.Web.UI.RadListView, "UniqueID":"ctl00$Cycle$C001$ctl00$ctl00$ctl00$listsControl","_clientSettings":,"_currentPageIndex":0,"_pageCount":1,"_pageSize":10,"clientStateFieldID":"ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl_ClientState", null, null, $get("ctl00_Cycle_C001_ctl00_ctl00_ctl00_listsControl")););<%@ Control Language="C#" %><%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %><%@ Register TagPrefix="sf" Namespace="Telerik.Sitefinity.Web.UI.PublicControls.BrowseAndEdit" Assembly="Telerik.Sitefinity" %><telerik:RadListView id="listsControl" runat="server" ItemPlaceholderId="ListContainer" EnableEmbeddedSkins="false" EnableEmbeddedBaseStylesheet="false"> <LayoutTemplate> <asp:PlaceHolder id="ListContainer" runat="server" /> </LayoutTemplate> <ItemTemplate> <telerik:RadListView ID="listItemsControl" runat="server" ItemPlaceholderID="ItemsContainer" EnableEmbeddedSkins="false" EnableEmbeddedBaseStylesheet="false"> <LayoutTemplate> <ul> <asp:PlaceHolder ID="ItemsContainer" runat="server" /> </ul> </LayoutTemplate> <ItemTemplate> <li> <asp:Literal runat="server" Text='<%# Eval("Content") %>' /> </li> </ItemTemplate> </telerik:RadListView> </ItemTemplate></telerik:RadListView>Hi Conrad Ehinger,
The extra inputs that you see rendered from the RadListView controls are coming from ASP.NET. The first one is the ControlState which cannot be disabled (the hidden inputs). The second one is the initialization of the RadListView client components. Since the RadListView for ASP.NET Ajax implements IScriptControl it needs this JS to initialize its client side component. This html cannot be removed.
If you want to build a RadListView with repeaters you have to create your own view for the control and there use repeater controls instead.

Radoslav,
I know this response is long past due - but how do I reference the same data source that the RadListView is referencing?
Thanks,
Chris
Hello Chris,
The datasource is not a property it is assigned when the NeedsDataSource event (ListsControl_NeedDataSource) of the RadListView is raised. This handler can be overridden if you inherit from the lists control. Inside we pass the datasource as bellow:
/// <summary>/// This method is called when the Lists control needs a data source to populate data./// </summary>/// <param name="sender">The RadListView which needs data</param>/// <param name="e"></param>protected virtual void ListsControl_NeedDataSource(object sender, RadListViewNeedDataSourceEventArgs e) this.ListsControl.DataSource = this.GetLists();
