accesing controls in code-behind

[R.A.M.]

Hello,
I am learning ASP.NET.
On .aspx page I have a data-list with text-box that I would like to read
during line modification.

<aspataList ...
OnEditCommand="Sample_Edit" >
...
<EditItemTemplate>
...
<asp:TextBox ID="SampleEdit" runat="server" />
...
</EditItemTemplate>
...
</aspataList>

In code-behind I have:

protected void Sample_Edit(object sender, DataListCommandEventArgs e)
{
...
string Sample = ((TextBox)e.Item.FindControl("SampleEdit")).Text;
// here problem
...
}

The problem is that although e.Item is fine, FindControl returns null.
Could you help me to programme it correctly?
Thank you !!!

I have also tried this way:
Sample =
((TextBox)SampleDataList.Items[e.Item.ItemIndex].FindControl("SampleEdit")).Text;

and this way:
Sample =
((TextBox)SampleDataList.SelectedItem.FindControl("SampleEdit")).Text;

but it doesn't work, either.

OK, I solved. SampleEdit is not accessible before edit mode set.

I have also tried this way:
Sample =
((TextBox)SampleDataList.Items[e.Item.ItemIndex].FindControl("SampleEdit")).Text;

and this way:
Sample =
((TextBox)SampleDataList.SelectedItem.FindControl("SampleEdit")).Text;

but it doesn't work, either.
