Hi geeks,

Just small verification.

I need to load "Select" in dropdownlist at pageload.

Then later on I add an item after typed in textbox.

C#

DropDownList d2 = (DropDownList)gvrow.Cells[2].FindControl("ddlfabric");
            d2.Items.Insert(0, new ListItem("Select"));
            if (txtfabric.Text != "")
            {   
                if(!d2.Items.Contains(new ListItem(txtfabric.Text)))
                {
                    d2.Items.Insert(1, txtfabric.Text);
                }
            }

The duplicates are removed but not the word "Select". Why Select is repeated ???

It's repeated because you added it again.

Might be due to the below line...

d2.Items.Insert(0, new ListItem("Select"));

I don't know how it is added again as I used items.insert("select") once.

In Page_Load()

C#

if (!Page.IsPostBack)
{
  //Add your "Select" Item here.
}
