Hi

C#

if (!IsPostBack)
  {

        ddlTableType.ClearSelection();

        ddlTableType.Items.Add(new ListItem("-Select-", "Select"));
        ddlTableType.Items.Add(new ListItem("Test Script Components"));
        ddlTableType.Items.Add(new ListItem( "Test Scripts"));
        ddlTableType.Items.Add(new ListItem( "Batch Scripts"));
  }


}







protected void ddlTableType_SelectedIndexChanged(object sender, EventArgs e)
{

    List<string> lsItems = null;

    if (ddlTableType.SelectedIndex == 1)
    {
        lsItems = ems.getTestScriptComponentsList(con);


    }

    else if (ddlTableType.SelectedIndex == 2)
    {
        lsItems = ems.getTestScriptsList(con);


    }

When the Event is trigered clear the dropdownlist before you populate it.

C#

List<string> lsItems = null;

            //Clear DropDownList
            DdlTableName.Items.clear()

        if (ddlTableType.SelectedIndex == 1)
        {
            lsItems = ems.getTestScriptComponentsList(con);

            
 
           // DataSet ds;

            //ds =lsItem

            foreach (var item in lsItems)
            {
                ddlTableName.Items.Add(item);
            }
 

 

        }
 
        else if (ddlTableType.SelectedIndex == 2)
        {
            lsItems = ems.getTestScriptsList(con);
 
            foreach (var item in lsItems)
            {
                ddlTableName.Items.Add(item);
            }
 
        }

Mark it as a solution then :p

DropDownListFirstList.Items.Clear() if you want to delete all items in the DropDownList

You just run it true a foreach loop.

C#

List<string> list = new List<string>();

            list.Add("one");
            list.Add("two");

            foreach (var item in list)
            {
                DropDownList1.Items.Add(item);
            }</string></string>
