If i click on edit button in gridview, the dropdownlist with selected item in the list should be displayed. But when im clicking on edit button,items in dropdownlist are displaying not with selected items in the list.
I want to display selected items when i click on edit button.

You can also do it something like this

in ASPX page

SelectedIndex='<%# SetSelectedIndex(DataBinder.Eval(Container.DataItem, "ItemID")) %>'

In code behind

C#

protected int SetSelectedIndex(object ITEMID)
    {
        int ret = 0;
        List<datatype> lst = get data in a list;
        ret = lst.FindIndex(st => st.ITEMID == Convert.ToInt32(ITEMID));
        return ret;
    }</datatype>

   int introwindex = Convert.ToInt32(e.CommandArgument.ToString());
  Call  you function to bind the Dropdown ;//
  DropDownList drp = MainGridView.Rows[introwindex].FindControl("DrpDown") as DropDownList;
  drp.DataSource=Call  you function to bind the Dropdown ;//
  drp.DataBind();  
  drp.SelectedItem.Text = myGridView.Rows[introwindex].Cells[1].Text;
