Retrieving a literal value from a datagrid footer

[nathan.cutmore]

BACKGROUND:
I have a bound datagrid with the following code -

<asp:datagrid id="dgla" OnItemCommand="declareDatagrid">
....
<Columns>
<ItemTemplate>
<asp:Literal id="lbOnLoan" Runat="server" />
</ItemTemplate>
<FooterTemplate>
<asp:Literal ID="lbTotalOnLoan" Runat="server" />
</FooterTemplate>
</columns>
</datagrid>

In the code behind I set the value of Literal.text when the datagrid is
bound.

On the same page that the datagrid is displayed I have a button that
when clicked sends an email - I have no problem coding the email
controls.

THE PROBLEM:
As part of the text of this email I want to include the VALUE that is
held the Literal.Text and I can't seem to extract it.

I think the solution is based on FINDCONTROL but I know that I am doing
something wrong.

Any solutions would be greatly appreciated.

You have to use FindControl on the last element in the DataGrid
object's Controls array.

Thanks Scott, very useful and very much appreciated.

The code (VB.NET) solution you led me to was as follows -

Dim txt As Literal
Dim footerIndex As Integer

footerIndex = CType(dgla.Controls(0).Controls.Count - 1, Integer)
txt =
CType(dgla.Controls(0).Controls(footerIndex).FindControl("lbTotalcopiesHeld"),
Literal)
Response.Write(txt.Text)

As you can see from my first meassage:
dgla - is my is my datagrid id
lbTotalcopiesHeld - the literal id where the value is held

I hope others find this solution useful.

Thanks Scott very useful and very much appreciated

The solution you led me to use (VB.NET) was -

Dim lit1 As Literal
Dim footerIndex1 As Integer

footerIndex1 = CType(dgla.Controls(0).Controls.Count - 1, Integer)
lit1 =
CType(dgla.Controls(0).Controls(footerIndex1).FindControl("lbTotalOnLoan"),
Literal)

response.write(lit1.Text)

Where 'dgla' is my Datagrid ID,, and 'lbTotalOnLoan' is the ID of the
Literal contained in the footer that holds the value I was trying to
extract.

I hope others find this simple solution useful.
