Hi again :)

I have a radgrid that I want to filter exactly like they do in this example:

http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridcomboajax/defaultcs.aspx?product=grid


the problem though is that I am not using a sqldatasource because the items in the grid need to be editable, so I am getting the source from the code behind.

Here is how the grid is getting it's data source:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            loadGrid();
        }
 
    }
 
    protected void loadGrid()
    {
        DATABASE dbcontext = new DATABASE();
        IEnumerable<LineItem> newlineitem = from p in dbcontext.LineItems
                                            select p;
        gridDataSource = newlineitem;
        RadGrid1.Rebind();
    }
 
public IEnumerable<LineItem> gridDataSource
    {
        set
        {
            Session["gridDataSource"] = value;
        }
        get
        {
            if (Session["gridDataSource"] == null)
                return null;
            else
            {
                return ((IEnumerable<LineItem>)Session["gridDataSource"]);
            }
        }
    }
 
protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
    {
        RadGrid1.DataSource = gridDataSource;
    }


How can I achieve this?

Hi Garrett,

Please remove the initial loadGrid logic and set the datasource of the grid only during NeedDataSource event.

Hope this helps. Looking forward to your reply.
