[Solved] Find Control RadFileExplorer in RadGrid

[cmr]

I am trying to pre-populate the RadFileExplorer's ViewPaths property when an item is selected for editing in the RadGrid control.  In other words, when a user needs to update a record in the grid, the file explorer should default to a specific directory based on certain criteria of the record.  However, when an attempt to locate the file explorer control is made, it cannot be found always resulting in a null assignment.  Is there a particular event to use prior to drawing the EditItemTemplate which contains the file explorer control?  Is there a better way to write the code to perform this dynamic behavior?  Below is some code snippets for the design and C#.

Thanks in advance

Design Page:

<telerik:RadGrid ID="exampleRadGrid" OnItemCommand="exampleRadGrid_ItemCommand">
   <Columns>
       <telerik:GridTemplateColumn UniqueName="FileName" DataField="FileName" HeaderText="FileName"  SortExpression="FileName">
          <ItemTemplate>
             <asp:Label runat="server" Text='<%#Eval("FileName") %>' ID="fileNameLabel" />
          </ItemTemplate>
          <EditItemTemplate>
             <telerik:RadTextBox runat="server" Text='<%# Bind("FileName") %>' ID="fileNameRadTextBox" />
             <telerik:RadFileExplorer ID="fileNameRadFileExplorer" runat="server" />
          </EditItemTemplate>
      </telerik:GridTemplateColumn>
   </Columns>
</telerik:RadGrid>

C# Code:

protected void exampleRadGrid_ItemCommand(object source, GridCommandEventArgs e)
{
   RadFileExplorer fileExplorer1 = (RadFileExplorer)FindControl("fileNameRadFileExplorer");
   RadFileExplorer fileExplorer2 = e.Item.FindControl("fileNameRadFileExplorer") as RadFileExplorer;
   // Both variables result in null.
}

Hi Cmr,

The controls (including RadFileExplorer control) cannot be found inside the exampleRadGrid_ItemCommand event because thy are not created yet. They can be accessed in RadGrid's ItemDataBound event, however.
