Problem Referencing OnEditCommand: Index out of Range

I've been searching all over and think I am close, but keep getting the
error "Index out of range" when trying to reference a nested datagrid when
an OnEditCommand event is raised.

When the OnEditCommand event is raised, I try to do the following:

1. Find the selected datalist item in which the nested datagrid raised the
event. (by calling getDataGridRefe rence and returning the DataList's

2. Once I know the selected datalist item, find the datagrid control within
that datalist item and set the selected row to edit mode.

The error occurs in my getDataGridRefe rence() function which tells me what
DataList item contains the "firing" datagrid. What am I doing wrong?

<asp:datalist OnItemDataBound ="OnItemDataBou ndEventHandler"
id="datalist_Pr ojectPhasesReso urces"
Runat="server" DataKeyField="p roject_phase_id _pk">
<ItemTemplate >
<%# DataBinder.Eval (Container.Data Item,
"project_phase_ name").ToString () %>

---------> Here is my nested DataGrid<--------
<asp:datagrid id="grid_Projec tPhasesResource s"
RUNAT="server" DataKeyField="p pr_id_pk"
OnItemDataBound ="dgPROnItemDat aBoundEventHand ler"
OnEditCommand=" pprOnEdit" OnCancelCommand ="pprOnCance l"
OnUpdateCommand ="pprUpdate" >
<asp:BoundColum n DataField="ppr_ id_pk" Visible="False"
Readonly="True" HeaderText=""></asp:BoundColumn >
<ItemTemplate >
<asp:Label Runat="server" ID="lblTotalHou rs" Text='<%#
Convert.ToStrin g(DataBinder.Ev al(Container.Da taItem,
"ppr_project_re source_hours")) %>' />
<EditItemTempla te>
<asp:TextBox Font-Size="8pt" Font-Name="Arial" Runat="server"
ID="editTotalHo urs" Text='<%#
Convert.ToStrin g(DataBinder.Ev al(Container.Da taItem,
"ppr_project_re source_hours")) %>' />
</EditItemTemplat e>
</asp:TemplateCol umn>
<asp:EditComman dColumn EditText="Edit" CancelText="Can cel"
UpdateText="Sav e"/>
------> End of nested DataGrid <-----------

<SeparatorTempl ate>
</SeparatorTempla te>
Code Behind event handler for datagrid

//When edit button is clicked, switch to textbox mode
public void pprOnEdit(Objec t source, DataGridCommand EventArgs e)
//Get a reference to the Grid in the current DataList row
DataGrid gridSelected = getDataGridRefe rence();

//Set the EditItemIndex to this Grid's item index
gridSelected.Ed itItemIndex = e.Item.ItemInde x;

//Call function to bind the grid again
//Get the selected DataList item index so we can find the current DataGrid
item to edit
public System.Web.UI.W ebControls.Data Grid getDataGridRefe rence()
DataListItem datalistitem =
datalist_Projec tPhasesResource s.Items[datalist_Projec tPhasesResource s.SelectedIndex];
return (DataGrid)datal istitem.FindCon trol("grid_Proj ectPhasesResour ces");
