[RESOLVED] Index Out of Range Error on DetailsView

Hi I have a DetailsView where I am trying to set some rows visible property to false.  I am getting the following error when I try to do that in the code behind:

Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

Here is my code.

                            BackColor="White" OnPreRender="dvMemberMeetingDetail_OnPreRender" OnItemUpdating="dvMemberMeetingDetail_ItemUpdating"
                           style="text-align: justify">
                            
                            
                            
                                
                            
                            
                            
                            
                                
                            
                            
                                
                                    
                                       
                                        
                                                                                     ConnectionString                                            ProviderName="System.Data.SqlClient"
                                            SelectCommand="SELECT [vcharMeetingName], [intMeetingID] FROM [tbl_Meetings]">
                                         
                                    
                                
                            
                           
                           
                           
                                            ID="btnSave" runat="server" Text="Save" onclick="btnSave_Click" />
                     Close
                

ConnectionString="<%$ ConnectionStrings:DoseRec_ABTConnectionString %>"
ProviderName="System.Data.SqlClient"
SelectCommand="SELECT tbl_Members.vcharFirstName, tbl_Members.vcharLastName, tbl_Meetings.vcharMeetingName, tbl_MeetingMembers.intMeetingMembersID, tbl_Meetings.intMeetingID FROM tbl_MeetingMembers INNER JOIN tbl_Meetings ON tbl_MeetingMembers.intMeetingID = tbl_Meetings.intMeetingID INNER JOIN tbl_Members ON tbl_MeetingMembers.intMemberID = tbl_Members.intMemberID WHERE (tbl_MeetingMembers.intMeetingMembersID = @intMeetingMembersID)">

This is the code that binds the data to the detailsview when an edit button is clicked in a gridview.

  protected void BtnViewDetails_Click(object sender, EventArgs e)
        {
            try
            {
                LinkButton btnDetails = sender as LinkButton;
                GridViewRow row = (GridViewRow)btnDetails.NamingContainer;
                this.sdsMeetingMemberDetail.SelectParameters.Clear();
                this.sdsMeetingMemberDetail.SelectParameters.Add("intMeetingMembersID", Convert.ToString(this.gvMeetingMembers.DataKeys[row.RowIndex].Value));
                this.dvMemberMeetingDetail.DataSource = sdsMeetingMemberDetail;
                this.dvMemberMeetingDetail.DataBind();
                this.updPnlCustomerDetail.Update();
                this.mdlPopup.Show();

            }

            catch (Exception ex)
            {
                lblMessage.Text = "An error occured.";
                Common.EventLogging.LogEvent(EventLogging.EventSeverityLevel.ErrorHighImpact, "An error occured.");
                //lblMessage.Text = ex.ToString();
                lblMessage.CssClass = "error";
                Common.EventLogging.LogEvent(ex);
                return;

            }
           
        }

This is where I try to set the visible property to false on some of the detailsview's rows.

protected void dvMemberMeetingDetail_OnPreRender(object sender, EventArgs e)
        {
            dvMemberMeetingDetail.Rows[0].Visible = false;
            dvMemberMeetingDetail.Rows[1].Visible = false;
            
        } 

Can anyone tell me what I'm doing wrong?  Thank you.
