Just looking for some clarification here. Would it be true to say that the main difference between RadMenu and RadNavigation is the Responsive behavior of the RadNavigation control?

I am trying to figure out which control to use, and am just in the beginning of my research into the new PageLayour and related parts of the Responsive infrastructure that Telerik offers. Is it possible to use the RadNavigation with images or templates? Furthermore, can those templates be turned on or off depending on the browser type it is being viewed with?

I would like to have a rich template based menu when viewed on a desktop client and the simple text-based menu on tablet or smartphone browsers.

Any feedback would be greatly appreciated as I try to wrap my brain around all this!

How Override Filter Pattern from RadGrid?

I get below form RadGrid.MasterVradGrid.MasterTableView.FilterExpression
filterExpression="(RequiredDate = DateTime.Parse("1/27/2015 12:00:00 AM"))"
if (!string.IsNullOrWhiteSpace(filterExpression))
{
query = query.Where(filterExpression);
}

Happen Exception.
======================================================================================================
An exception of type 'System.NotSupportedException' occurred in EntityFramework.SqlServer.dll but was not handled in user code

Additional information: LINQ to Entities does not recognize the method 'System.DateTime Parse(System.String)' method, and this method cannot be translated into a store expression.
======================================================================================================

Because I use EF6 it no support 'System.DateTime.Parse' method

I want change filter expression ,I hope result below example.
query = query.Where("(RequiredDate >= DateTime(2015,1,29))");

LinqDataSource, select new { ... } = "The state information is invalid for this page and might be corrupted."

I'm using the RadGrid with a LinqDataSource and keep getting "The state information is invalid for this page and might be corrupted." error

What am I doing wrong?

The problem only occurs on the production server.
Windows Server 2008 setup in a web farm of 3 computers.

The following code generates an error. on the production server on postbacks (e.g. sorting, filtering or paging)... but not every single postback (about 1 in 3).

I've looked everywhere to see what the problem to this is... the following link is the closest to help identify the problem that I've come across even though it's an old post seems to be the same sort of problem
http://www.telerik.com/community/forums/aspnet-ajax/grid/does-current-futures-build-support-linq-datasources.aspx

To test I've created the same page but linked the LinqDataSource to a GridView and don't get the error paging and sorting work fine.

    
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head runat="server"> 
        
                <title></title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                <div> 
        
                    <asp:LinqDataSource ID="LinqDataSource1" runat="server"  
        
                        onselecting="LinqDataSource1_Selecting"> 
        
                    </asp:LinqDataSource> 
        
                    <asp:GridView ID="GridView1" runat="server" AllowPaging="True"  
        
                        AllowSorting="True" DataSourceID="LinqDataSource1"> 
        
                    </asp:GridView> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

also if I just change the LinqDataSource1_Selecting to not use "select new { ... } I also don't get the error... e.g.

    
                protected void LinqDataSource1_Selecting(object sender, LinqDataSourceSelectEventArgs e) 
        
                { 
        
                    DynamicData01DataContext dc = new DynamicData01DataContext(); 
        
                    var products = from p in dc.tbl_Products 
        
                                   select p; 
        
                    e.Result = products; 
        
                }

Please help... I really need to fix this problem.
Have I missed something obvious?
Could this have something to do with the Production server running as a webfarm?
Has anyone else experienced this problem?
