Browser Back button and reset PageIndex in Grid

[Bryan]

Hello,
I know Telerik Grid does not go back to previous state in case of paging when ajaxfied but i found from telerik we can impement Scriptmanager Naviate method to reset Index but its not working it always go for first index on browser back button.
I have scriptmanager in MasterPage and in webpart i have added script manage Proxy control.

Please find code 

<asp:ScriptManager id="ScriptManager" runat="server"
                       EnableHistory="true"
                       EnablePageMethods="false"
                       EnablePartialRendering="true"
                       EnableScriptGlobalization="true"
                       EnableScriptLocalization="true" />

in Webpart .ascx File

<asp:ScriptManagerProxy ID="wsScriptManagerProxy" runat="server" OnNavigate="ScriptManager_Navigate" />

Code 

private static string pageKey = "p";
protected void ScriptManager_Navigate(object sender, HistoryEventArgs e)
        {
            if (e.State.Count <= 0)
            {
                // Setup default state
                workspaceGrid.MasterTableView.CurrentPageIndex = 0;
                return;
            }

            string key = e.State.AllKeys[0];
            string state = String.Empty;

            if (String.Equals(key, pageKey))
            {
                state = e.State[key];
                int pageIndex = int.Parse(state);
                workspaceGrid.MasterTableView.CurrentPageIndex = pageIndex;
                workspaceGrid.MasterTableView.Rebind();
            }
        }
protected void workspaceGrid_PageIndexChanged(object sender, GridPageChangedEventArgs e)
        {
            //string state = (sender as RadGrid).MasterTableView.CurrentPageIndex.ToString();
            string state = e.NewPageIndex.ToString();
            ScriptManager.GetCurrent(this.Page).AddHistoryPoint(pageKey, state);
        }

Thanks

Thanks Pavlina for your reply and code.I will give it try but it will be great if you provide code which best suit to my case like having scriptManager control in master page and SciptmanagerProxy control in content page.

Thanks

Hi,

Can you verify that the state of the grid pager is persisted in SharePoint when RadAjax is disabled(EnableAjax property is set to false) and you click browser back button? You can also check if the state of the other control features can be persisted from back button in SharePoint.

Hello Bryan,

Please, open up a formal support ticket and attache the implementation of the web part - it is difficult going by the code-snippets provided to say what exactly is going wrong with the code. Thanks for that.
