is their selectedvalue property for drop downlist???
usually, we can get selected list items, text and value associated with it, like

question1.selectedvalue
question1.selecteditem.text

Of course there is :) Go to the link below, search for 'SelectedIndex', 'SelectedValue' and 'SelectedItem'. Play with these properties and you'll figure it out

Good luck :)

Here is the code..Hope it will help you..

C#

string sqlQuery = "Select " + colName + ",0 as " + colValue + " Union Select " + colName + "," + colValue + " from " + tblName;
            if (srchCodn != "")
            {
                sqlQuery += " " + srchCodn;
            }
            adp = new SqlDataAdapter(sqlQuery, conn);
            tbl = new DataTable();
            adp.Fill(tbl);
            ddlList.DataSource = tbl;
            ddlList.DataTextField = colName;
            ddlList.DataValueField = colValue;
            ddlList.DataBind();

After Binding ddlList you can get the value using ddlList.DataValueField.
