    Hello Dinesh,

    There is no built-in client-side functionality that will resize the DockZone. This can be done on the server only.

    Here is a work around that will exchange the width and height of two DockingZones, but please note that, these changes will not be persisted after a postback:
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
    <head id="Head1" runat="server">
        <telerik:RadScriptBlock ID="RadCodeBlock1" runat="server">
            <script type="text/javascript">
                function ChangeWidth()
                    var dockZone = $telerik.findDockZone("<%=RadDockZone1.ClientID %>");
                    dockZone.get_element().style.height = 600;
                    // = 600;
                var originalZoneID = "";
                var originalIndex = "";
                function OnClientDragStart(dock, args)
                    originalZoneID = dock.get_dockZoneID();
                    originalIndex = dock.get_index();
                function OnClientDockPositionChanged(dock, args)
                    var currentZone = dock.get_dockZone();
                    var currentIndex = dock.get_index();
                    var docks = currentZone.get_docks();
                    if (currentZone.get_id() != originalZoneID)
                        var originalZoneElement = $find(originalZoneID).get_element();
                        var currentZoneElement = currentZone.get_element();
                        var originalZone_MinHeight =;
                        var originalZone_Height =;
                        var originalZone_Width =;
               = originalZone_MinHeight;
               = originalZone_Height;
               = originalZone_Width;
        <style type="text/css">
                float: left;
                margin-right: 10px;
            .rdTitleBar EM
                width: 100% !important;
                position: absolute !important;
                right: 7px !important;
        <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server">
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
            <asp:Button ID="Button1" runat="server" Text="Postback" />
            <input type="button" value="Set Width" onclick="ChangeWidth(); return false;" />
            <telerik:RadDockLayout ID="RadDockLayout1" runat="server">
                <telerik:RadDockZone ID="RadDockZone1" runat="server" MinHeight="300px" Width="300px">
                    <telerik:RadDock ID="RadDock1" runat="server" Title="RadDock-Title" Width="300px"
                        Skin="Hay" DockMode="Docked" OnClientDragStart="OnClientDragStart" OnClientDockPositionChanged="OnClientDockPositionChanged">
                            <br />
                            <br />
                            <br />
                            <br />
                            <br />
                            <br />
                            <br />
                            <br />
                            <br />
                            <br />
                <telerik:RadDockZone ID="RadDockZone2" runat="server" MinHeight="200px" Width="600px">

    This can be easily done in the code behind by handling the DockPositionaChanged event and setting the AutoPostBack property to true. The original zone ID should be retrieved at Page.Init using the dock.DockZoneID property, before the new zone ID is applied.
