In the above  code i am not added below code because in my master page i included that script manager
 <telerik:RadScriptManager ID="radAjaxScriptManager1" runat="server">
    </telerik:RadScriptManager>
The following snippet used for the button click event to navigate the tab from one page to another

                   RadTabStrip tc = null;
                    System.Web.UI.WebControls.Literal ltMetaTags = null;
                    Control ctl = this.Parent.Parent;
                    tc = (RadTabStrip)ctl.FindControl("RadTabStrip1");
                    if (tc != null)
                    {
                        tc.TabIndex = 1;
                        tc.SelectedIndex = 1;
                        GoToNextTab();
                        GoToNextPageView();
                    }
        private void GoToNextTab()
        {
            RadTabStrip tabStrip = (RadTabStrip)this.NamingContainer.FindControl("RadTabStrip1");
            RadTab PartyDetailsTab = tabStrip.FindTabByValue("PartyDetails");
            PartyDetailsTab.Enabled = true;
            PartyDetailsTab.SelectedIndex = 1;
            PartyDetailsTab.Selected = true;
            
        }
        private void GoToNextPageView()
        {
            RadMultiPage multiPage = (RadMultiPage)this.NamingContainer.FindControl("RadMultiPage1");
            RadPageView PartyDetailsPageView = multiPage.FindPageViewByID("RadPageView2");
            PartyDetailsPageView.TabIndex = 1;
            PartyDetailsPageView.Selected = true;

Hello Kaleswar,

Since you had ajaxified the controls in the RadTabStrip and RadMultiPage, you should add an ajax setting, in order to specify that the button should update the RadTabStrip and the RadMuliPage. You could achieve this, following the approach demonstrated in this article or you could directly add the AjaxSettings in the UserControl in the following manner:

protected void Page_Load(object sender, EventArgs e)
    {
        RadTabStrip tabStrip = (RadTabStrip)this.NamingContainer.FindControl("RadTabStrip1");
        RadMultiPage multiPage = (RadMultiPage)this.NamingContainer.FindControl("RadMultiPage1");

        RadAjaxManager AjaxManager = RadAjaxManager.GetCurrent(Page);
        AjaxManager.AjaxSettings.AddAjaxSetting(RadButton1, tabStrip);
        AjaxManager.AjaxSettings.AddAjaxSetting(RadButton1, multiPage);
    }

In addition, I noticed that you are attempting to find the Tab by its value (using tabStrip.FindTabByValue("Party Details") ), but I noticed that you did not set any value for the RadTabs. I would suggest you either set the value of the Tabs (using Value property) or you could use the FindTabByText() method.
