Sorting a Dropdownlist

Hi rohatash,

Here is your solution


using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

public partial class Default3 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        DropDownList1.Items.Add("raj");
        DropDownList1.Items.Add("Berry");
        DropDownList1.Items.Add("Arun");
        DropDownList1.Items.Add("Crish");
        SortDDL(ref this.DropDownList1);

    }
    private void SortDDL(ref DropDownList objDDL)
    {
        ArrayList textList = new ArrayList();
        ArrayList valueList = new ArrayList();


        foreach (ListItem li in objDDL.Items)
        {
            textList.Add(li.Text);
        }

        textList.Sort();


        foreach (object item in textList)
        {
            string value = objDDL.Items.FindByText(item.ToString()).Value;
            valueList.Add(value);
        }
        objDDL.Items.Clear();

        for (int i = 0; i < textList.Count; i++)
        {
            ListItem objItem = new ListItem(textList[i].ToString(), valueList[i].ToString());
            objDDL.Items.Add(objItem);
        }
    }

}

Hi kumar,

       Right Click DropdownList and Goto Properties -> You can find a Property names SORTED -> Make this property from false to true. it will automatically sort all the items
