using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class manager_view_distributors : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        AlternaDB.MarketingDataContext db = new AlternaDB.MarketingDataContext();

        var products = from p in db.Distributors

                       select new { p.DistributorID, Company_Name = p.CompanyName, Address = p.AddressLine1, p.City, Zip_Code = p.ZipCode, p.State, First_Name = p.Contact1FirstName, Last_Name = p.Contact1LastName, Area_Code = p.Contact1WorkAreaCode, Phone = p.Contact1WorkNumber, Num_Stores = p.NumStores, Num_DSC = p.NumDsc };
                      
                       GridView1.DataSource = products;
        GridView1.DataBind();

            }
  protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) 
{

    GridView1.PageSize = Int32.Parse(DropDownList1.SelectedValue); this.GetData(); 
}
  private void GetData()
  {
      GridView1.DataBind();

  }
    
  protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
  {

      GridView1.PageIndex = e.NewPageIndex;

      this.GetData();
  }
    protected void LinkButton1_Click(object sender, EventArgs e)
    {
        if (this.rdoBtnListExportOptions.SelectedIndex == 1)
        {
            //  the user wants all rows exported, turn off paging
            //  and rebing the grid before sending it to the export
            //  utility
            ExportExcelColumns();
            this.GridView1.PageSize = 1000000;
            GridView1.DataBind();
        }
        else if (this.rdoBtnListExportOptions.SelectedIndex == 2)
        {
            //  the user wants just the first 100,
            //  adjust the PageSize and rebind
            ExportExcelColumns();
            this.GridView1.PageSize = 100;
            GridView1.DataBind();


        }
        //Current Page export
