Group Title

RadTileList offers group titles (Figure 1) as of Q1 2016. To set the title of a group, use its Title property (Example 1). You can also set it on the client side via the set_groupTitle method (Example 2).

When data binding a TileList control, you can set the group titles declaratively when you define the groups structure. Alternatively, you can use the OnTileDataBound event to access the associated data item and set a group's title according to your business logic. You can see this in action in the Declarative DataSource Live Demo.

Example 1: Set group title via server property. This code results in Figure 1.

<telerik:RadTileList RenderMode="Lightweight" runat="server" ID="RadTileList1">
    <Groups>
        <telerik:TileGroup Title="First Group">
            <telerik:RadTextTile runat="server" ID="RadTextTile1" Text="tile 1, group 1"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile2" Text="tile 2, group 1"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile3" Text="tile 3, group 1"></telerik:RadTextTile>
        </telerik:TileGroup>
        <telerik:TileGroup Title="Second Group">
            <telerik:RadTextTile runat="server" ID="RadTextTile4" Text="tile 1, group 2"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile5" Text="tile 2, group 2"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile6" Text="tile 3, group 2"></telerik:RadTextTile>
        </telerik:TileGroup>
    </Groups>
</telerik:RadTileList>

Example 2: Set group title on the client side.

<asp:Button ID="Button1" Text="set group titles" OnClientClick="setGroupTitles(); return false;" runat="server" />
<script type="text/javascript">
    function setGroupTitles() {
        var tileList = $find("<%=RadTileList1.ClientID%>");
        var groups = tileList.get_groups();
        groups.forEach(function (group, index) {
            var tileCount = group.get_tiles().get_count();
            var title = "Tiles number: " + tileCount;
            tileList.set_groupTitle(group, title);
        });
    }
</script>
<telerik:RadTileList RenderMode="Lightweight" runat="server" ID="RadTileList1">
    <Groups>
        <telerik:TileGroup>
            <telerik:RadTextTile runat="server" ID="RadTextTile1" Text="tile 1, group 1"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile2" Text="tile 2, group 1"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile3" Text="tile 3, group 1"></telerik:RadTextTile>
        </telerik:TileGroup>
        <telerik:TileGroup>
            <telerik:RadTextTile runat="server" ID="RadTextTile4" Text="tile 1, group 2"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile5" Text="tile 2, group 2"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile6" Text="tile 3, group 2"></telerik:RadTextTile>
        </telerik:TileGroup>
    </Groups>
</telerik:RadTileList>

Example 3: Clearing group titles on the client.

<asp:Button ID="Button1" Text="clear group titles" OnClientClick="clearGroupTitles(); return false;" runat="server" />
<script type="text/javascript">
    function clearGroupTitles() {
        var tileList = $find("<%=RadTileList1.ClientID%>");
        tileList.clearGroupTitles();
    }
</script>
<telerik:RadTileList RenderMode="Lightweight" runat="server" ID="RadTileList1">
    <Groups>
        <telerik:TileGroup Title="First Group">
            <telerik:RadTextTile runat="server" ID="RadTextTile1" Text="tile 1, group 1"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile2" Text="tile 2, group 1"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile3" Text="tile 3, group 1"></telerik:RadTextTile>
        </telerik:TileGroup>
        <telerik:TileGroup Title="Second Group">
            <telerik:RadTextTile runat="server" ID="RadTextTile4" Text="tile 1, group 2"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile5" Text="tile 2, group 2"></telerik:RadTextTile>
            <telerik:RadTextTile runat="server" ID="RadTextTile6" Text="tile 3, group 2"></telerik:RadTextTile>
        </telerik:TileGroup>
    </Groups>
