Access the FooterTemplates TextBox control on the Button Click Event

[Arulraja]

Hello,

I have the following code in the .aspx file

<asp:TemplateColumn HeaderText=" FG Name">
<HeaderStyle ForeColor="White"></HeaderStyle>
<ItemStyle HorizontalAlign="Center" Width="200px"></ItemStyle>
<ItemTemplate>
<asp:TextBox id=txt_fg Width="200px" Runat="server" Text='<%#
DataBinder.Eval(Container,"DataItem.family_group_name")%>'
MaxLength="100" />
</ItemTemplate>
<FooterTemplate>
<asp:TextBox id="footerfg" Width="200px" runat="server" />
</FooterTemplate>
</asp:TemplateColumn>


In the code behind button click event i have the follwing code

foreach (DataGridItem item in grid_1.Items)
{
// get values from UI
TextBox txtf = (TextBox)item.Cells[1].FindControl("txt_fg");
}


But this one is giving me only the DataGridItems(Items and
ALternativeItems) not the Footer Items. If I pass the Footer TextBox
ID to the FindControl method it return's a null.

If I try the same code in the ItemCreated Event the TextBox "TEXT"
property return's empty string.

Can somebody help me to fix this problem? or Direct me how to access
the Footer TextBox value on the Button Click event.

Thx
Arul

Hi,

//Header
DataGridItem header=(DataGridItem)dg.Controls[0].Controls[0];

//Footer
DataGridItem footer=
(DataGridItem)dg.Controls[0].Controls[Controls[0].Controls.Count - 1];

you can then search up controls from these. REason for this structure is
that header & footer are actually controls in DataGridTable instance which
is a child control of DataGrid (DataGridTable is actually the grid itself as
Table and some of the layout functionality we see in DataGrid comes from
this table).

You could access then easier when you are on say ItemCreated event when the
event is raised for every item. In your case you were accessing them by
looping through the Items collection so it needed bit another approach.
