TileProperties - dictionary with keys of type string (property name) and values of type object (value properties).

Secondly, should pay attention to the type of the transmitted value, which should be the heir of the type of the corresponding property or be them.

an Example of using properties TileProperties

For a class of tiles ObjectTile sets the property AttributeRenderers.

//expander control class MasterExpander 
Dictionary<string, AttributeRenderer> renderers = 
                new Dictionary<string, AttributeRenderer>();
renderers.Add("Nickname", delegate (object val)
                            return string.Format("<b>{0}</b>", val);
expander.TileProperties.Add(ObjectTile.AttributeRenderersPropertyName, renderers);

        <add verb="*" path="ObjectTileViewService.asmx" validate="false" 
          type="ICSSoft.STORMNET.Web.AjaxControls.HandlerFactories.ObjectTileViewHandlerFactory" />

<%@ Register TagPrefix="ac" Namespace="ICSSoft.STORMNET.Web.AjaxControls" Assembly="ICSSoft.STORMNET.Web.AjaxControls" %>

The control ObjectTileView must be present on the page ScriptManager’a:

<asp:ScriptManager runat="server"/>

To desired location add the control:

<ac:ObjectTileView runat="server" ID="myTileView"/>

// Set the view according to which database will be loaded and displayed objects 
myTileView.View = Information.GetView("DataTypeL", typeof(DataType));
// Set the class of the object that will be displayed in the control 
myTileView.Type = typeof(DataType);
