Solution 1

Dropdownlist1.Items.Insert(0,"-ALL-");

Add like this after binding values from collection/db.

C#:

C#

DataSet ds;

DataTable dt;

DataRow newRow;

// get the drop down values from the SP as a dataset
ds = webService.getMyDDLValues();

// now add the values to the drop down list
if ((ds.Tables.Count > 0) && (ds.Tables[0].Rows.Count > 0))
{
        // grab the table from the dataset
        dt = ds.Tables[0];

        // create the new row
        newRow = dt.NewRow();

    // specify the select item's value
        newRow["SELECT_VALUE"] = "-1";

        // specify the text to show in the drop down
        neRow["SELECT_TEXT"] = "--ALL--";

    // add the row at position 0
        dt.Rows.InsertAt(newRow, 0);

        // now bind the table to the control
        myDDL.DataSource = dt;
        myDDL.DataBind();
}

ASP.NET:

ASP.NET

<asp:DropDownList CssClass="myDDLClass" ID="myDDL" DataValueField="SELECT_VALUE" DataTextField="SELECT_TEXT" runat="server" ></asp:DropDownList>
