FindControl in FormView

[Arthur.Net]

I am having trouble finding a checkbox control within a formview. I
can find other textboxes and such in here. Any ideas?

Here is the form simplified:

<asp:FormView ID="formCategory" runat="server"
DataSourceID="dsCategoryForm">
<ItemTemplate>
<asp:CheckBoxList ID="chkUDF" runat="server"
DataSourceID="dsUDFchk" DataTextField="FieldNameStr"
DataValueField="BaseUDFID"></asp:CheckBoxList>
</ItemTemplate>
</asp:FormView>

Here is the code that runs:
CheckBoxList _chkUDF =
(CheckBoxList)formCategory.FindControl("chkUDF");

foreach (ListItem chk in _chkUDF.Items)
{
chk.Selected = false;
}

foreach (ListItem chk in _chkUDF.Items)
{
chk.Selected = false;

}

look at the rendered html.
If i remember correctly , i think something is append to the control
name..
that mite be the reason why you cant find it.

Hi,

The control is renamed based on each row. It's easy to see that there
will be one control per row, so all of them cannot be named the same.
What is what you want to do?
There might be a better way of doing it

It is not failing on the loop. That works in many previous
incarnations. It says it is failing because this part is not finding
anything..
CheckBoxList _chkUDF =
(CheckBoxList)formCategory.FindControl("chkUDF");

I am sure there are many better ways, but I have been programming .Net
for exactly one week.

That is what I meant, each Row has an isntance of that control, of
course that each particular contorl has a different name.
Take a look at the code of the page. you will see the real name of the
control.

In response of what event you are running tht code?
