RadGrid Problem

[Ricardo]

Hello,

i'm having a problem with my RadGrid, At this moment i need to bind data to my Grid using 2 diferent Store Procedures, mapped on my .edmx.

The idea is to have two buttons, each one to call a procedure. At this moment My problem is when I click on a collumn to sort data, my grid comes blank....I need to allow my RadGrid to sort collumns but for the specific procedure that was bind at last.

How can i do that?

My code is

public partial class InvoicesScalingDefault : iConnect.Web.iConnect, IInvoicesScale
    {
        private InvoicesScalePresenter _presenter;

        public System.Collections.Generic.IList<Data.SapDocuments> SapDocuments
        {
            get;
            set;
        }

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {

                this._presenter.OnViewInitialized();

                LoadData();
            }
            this._presenter.OnViewLoaded();

        }

        [CreateNew]
        public InvoicesScalePresenter Presenter
        {
            set
            {
                this._presenter = value;
                this._presenter.View = this;
            }
        }


        /// <summary>
        /// Carregar RadGrid1 com o objecto SapDocuments
        /// </summary>
        private void LoadData()
        {

            string user = Page.User.Identity.Name.Substring(Page.User.Identity.Name.IndexOf("\\") + 1);

            EscalonamentoFacturasEntities objectContx = new EscalonamentoFacturasEntities();
            RadGrid1.DataSource = objectContx.ShowUnprocessedInvoices(user);
            //RadGrid1.DataBind();

        }


protected void RadGrid1_GridExporting(object sender, GridExportingArgs e)
        {
            e.ExportOutput = e.ExportOutput.Replace("\"\r\n\"", "\"\r\n\"'");
        }

protected void ShowProcessed_Click(object sender, EventArgs e)
        {
            string user = Page.User.Identity.Name.Substring(Page.User.Identity.Name.IndexOf("\\") + 1);

            EscalonamentoFacturasEntities objectContx = new EscalonamentoFacturasEntities();
            RadGrid1.DataSource = objectContx.ShowProcessedInvoices(user);
            RadGrid1.DataBind();


        }


        protected void ShowUnProcessed_Click(object sender, EventArgs e)
        {
            LoadData();

        }

Hello Ricardo,

RadGird does not support advanced features like sorting, paging etc when you are using SimpleDataBinding. Make sure that you use Advanced data binding using NeedDataSource event. Check the following help documentation which explains more about this.
Advanced Data-binding (using NeedDataSource event).

Thanks,
Princy.

Hello,

if i use ViewState to keep both two datasource i can solve it??

Last Code

protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {

                this._presenter.OnViewInitialized();

                string user = Page.User.Identity.Name.Substring(Page.User.Identity.Name.IndexOf("\\") + 1);
                EscalonamentoFacturasEntities objectContx = new EscalonamentoFacturasEntities();
                ViewState["Data"] = objectContx.ShowUnprocessedInvoices(user);
                RadGrid1.DataSource = objectContx.ShowUnprocessedInvoices(user);
                RadGrid1.DataBind();


            }
            this._presenter.OnViewLoaded();

            RadGrid1.DataSource = (ShowUnprocessedInvoices_Result)ViewState["Data"];
            RadGrid1.DataBind();

        }


protected void ShowProcessed_Click(object sender, EventArgs e)
        {
            string user = Page.User.Identity.Name.Substring(Page.User.Identity.Name.IndexOf("\\") + 1);

            EscalonamentoFacturasEntities objectContx = new EscalonamentoFacturasEntities();
            RadGrid1.DataSource = objectContx.ShowProcessedInvoices(user);
            RadGrid1.DataBind();

            ViewState["Data"] = objectContx.ShowProcessedInvoices(user);

        }


        protected void ShowUnProcessed_Click(object sender, EventArgs e)
        {
            string user = Page.User.Identity.Name.Substring(Page.User.Identity.Name.IndexOf("\\") + 1);

            EscalonamentoFacturasEntities objectContx = new EscalonamentoFacturasEntities();
            RadGrid1.DataSource = objectContx.ShowUnprocessedInvoices(user);
            RadGrid1.DataBind();

            ViewState["Data"] = objectContx.ShowUnprocessedInvoices(user);

        }

I have solved the problem using ViewState however know

I have a problem on my RadGrid1. two of the grid columns are navigation properties...The problem is when i enter on the page, all columns fields has data.But when i click to sort those two columns came without values..
 
I have already verify that the list i'm using as DataSource, has allways those two columns with values...The problem is that when i sort the Grid comes without values on "Priority" and "Process" fields.....
