Here is my form:

    
                        <telerik:RadGrid ID="PhoneGrid" runat="server" GridLines="None" OnUpdateCommand="PhoneGrid_OnUpdateCommand" OnDeleteCommand="PhoneGrid_OnDeleteCommand"

                        </asp:ObjectDataSource>

Here is my code:

    
                    protected void PhoneGrid_OnUpdateCommand(object source, GridCommandEventArgs e)  
        
                    {  
        
                        GridEditableItem editedItem = e.Item as GridEditableItem;  
        
                        //Get the primary key value using the DataKeyValue.       
        
                        if (editedItem != null)  
        
                        {  
        
                            var P = new Phone();  
        
                            P.PhoneID = (Int64)editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["PhoneID"];  
        
                            //Access the textbox from the edit form template and store the values in string variables.       
        
                            P.PhoneNumber = (editedItem["PhoneNumber"].Controls[0] as TextBox).Text;  
        
                            // ATTEMPT TWO - I get Unable to cast object of type 'Telerik.Web.UI.RadComboBox' to type 'System.Web.UI.WebControls.DropDownList'.  
        
                            DropDownList ddl = (DropDownList)editedItem["ddlPhoneTypeID"].Controls[0];  
        
                            string selectedVal = ddl.SelectedValue;  
        
                            P.PhoneTypeID = Convert.ToInt32(selectedVal);  
        
                            // ATTEMPT One - I get NULL here  
        
                            //P.PhoneTypeID = Convert.ToInt32((editedItem["PhoneTypeID"].Controls[0] as DropDownList).SelectedValue);  
        
                            P.isPreferred = (editedItem["isPreferred"].Controls[0] as CheckBox).Checked;  
        
                            PeopleMainDAL.puPhoneList(P);  
        
                        }  
        
                    }

I am trying to get the value from the drop down list upon edit and I am either getting a null exception or the second attempt I was getting a casting error. Help!
