Iftikar's suggestion also works if (as I assumed originally) the DropDownList is within some container on the page. But as Sanjeeb said, you are stuck with the contents of the DataValueField rather than the DataTextField if you use Request.Form. If you want the DataTextField, then I'd use FindControl instead: DropDownList dropDown = FindControl(ddl.UniqueID) as DropDownList; if (dropDown != null) Label1.Text = dropDown.SelectedItem.Text;

If you are using UserControl then you need to use Request.Form[ddl.UniqueID]; Regards, Iftikar

yes you can do it but it will give you the dropdownlist valuefield. check the below code. in aspx: in cs i bind drop down in database: protected void Page_Load(object sender, EventArgs e) { SqlConnection con = new SqlConnection("your connection string"); SqlCommand cmd = new SqlCommand("select DEPTNO,DNAME from DEPT", con); SqlDataAdapter da = new SqlDataAdapter(cmd); DataSet ds = new DataSet(); da.Fill(ds); DropDownList1.DataTextField = "DEPTNO"; DropDownList1.DataValueField = "DNAME"; DropDownList1.DataSource = ds.Tables[0]; DropDownList1.DataBind(); } protected void Button1_Click(object sender, EventArgs e) { Label1.Text = Request.Form["DropDownList1"].ToString(); }

Hi, If it is a server control then you can get it. Regards, Iftikar

No, I don't think so because, for one thing, the name of the variable will not be the same as the ID of the control. See this thread: http://stackoverflow.com/questions/9044236/can-not-get-request-form-get-valus-from-aspx-page-that-wrappe-withe-contentplace
