Filtering not working on simple databind. Even when the filter tries to display it doesn't even show the no records template.  Code below.

Hey Jon-Jon,

Well, I tested your grid code outside of there and had no problems with it, worked like a charm when I attached a simple SQL data source.  Where are you using this control at, perhaps there is some global css that is giving it trouble?  Could you post the code for the page containing this control and for where the databind is coming from?

Well we have this content page nested within a default page that is nested with in a master.content page.  A global css could very well be the cause because we haven't even started on dealing with the levels of where the css is applied to what page.

The code I used to bind is a basic bind and is as follows:
 
public void BuildInboxPresentation() 
    { 
        this.RadGridReportInbox.DataSource = null
        this.RadGridReportInbox.DataSourceID = null
 
        List<System.IO.FileInfo> FileList = new List<System.IO.FileInfo>(); 
        foreach (System.IO.FileInfo fi in this.FileInfo) 
        { 
            FileList.Add(fi); 
        } 
        this.RadGridReportInbox.DataSource = this.FileInfo; 
        this.RadGridReportInbox.DataBind(); 
 
    } 

Hope this helps...if you need anything else let me know.

Hello Jon-Jon Kershaw,

The filtering feature of RadGrid is not supported with simple binding and DataBind() calls. This is outlined in the Description section of the following online demo of the product:

http://demos.telerik.com/aspnet-ajax/Grid/Examples/GeneralFeatures/Filtering/DefaultCS.aspx

If you would like to take advantage of this grid feature, you will need to switch to advanced binding using NeedDataSource event handling or a data source control (as shown in the example linked above).

We do not want to use the SQL in the our code or XML is there any other way?

We are using a MVC for the project and accessing the data in a datalayer so what do you suggest?

Hi Jon-Jon Kershaw,

RadGrid does not support grouping when used inside ASP.NET MVC and this detail is depicted in the following topic from the documentation:

http://www.telerik.com/help/aspnet-ajax/mvc-limitations.html

If the grouping feature of the grid is essential part of your implementation, you may consider using a hybrid application and nest the control in a regular ASP.NET page as discussed in this blog post.

Kind regards,
Sebastian
