I am trying to insert the selected value of a dropdown box into the database and I cant get it - anyone know?

            string sqlStr = "";
            int mgrid = user.UserID;
            int selecteduser;
            Control myControl = FindControl("ddlusers");
            if (myControl != null || Convert.ToString(myControl) != "--Please Select--")
            {

                selecteduser = myControl.SelectedValue; <-- selected value doesnot exist 
                
            }
            sqlStr += "Insert Into ManagerStaff (mgruseruid,staffuseruid) Values (mgrid,selecteduser) ";
            using (SqlConnection conn = new SqlConnection(conStr))
            using (SqlCommand cmd = new SqlCommand(sqlStr, conn))
            {
                cmd.CommandType = System.Data.CommandType.Text;
                cmd.Connection.Open();
                cmd.ExecuteNonQuery();
            }

'System.Web.UI.Control' does not contain a definition for 'SelectedValue' and no extension method 'SelectedValue' accepting a first argument of type 'System.Web.UI.Control' could be found (are you missing a using directive or an assembly reference?)

Try
selecteduser = ((DropDownList)myControl).SelectedValue.ToString();

Open in new window

This will cast the control as a DropDownList, as well as return a string you can use.

On what line? If you debug, does it even get to line 8 of your original post?

This is not a "DropDownList" it is a telerik specific control called "GridDropDownColumn". You can try replacing "DropDownList" with "GridDropDownColumn" in the cast. Not sure that's your biggest problem, though. Still not sure if your findcontrol is even returning a control.

GridEditableItem item = e.Item as GridEditableItem;

                selecteduser = Convert.ToInt32((item["ddlusers"].Controls[0] as RadComboBox).SelectedValue);
