Hi,
This might be a little odd but I need to implement a back/"return to
previous page" function from different pages within my asp.net
application. The page the back button on has a property that stores
an id value that the page i will be returning to will require to
display data. The entire application does not use querystrings, and
I don't want to use session variables to store this value.
The page also has controls that require validation (that a value
exists, numeric etc). If the back button is created and has
CausesValidatio n set to True, I obviously get validation errors.
If the back button has CausesValidatio n set to false, the property on
the page is automatically destroyed.
Is there a way to implement my back functionality without resorting to
querystring or session variables?
Cheers
Greg

Have you tried the properties: CommandName and CommandArg on the button? For
example: CommandName="Ba ck" and CommandArg= the ID. Then setup the OnCommand
event handler to intercept this click.

Hi Peter,
I've tried your suggestion - the validators still display, overriding
everything.
I did the following (just to confirm):
<asp:button id="btnBack" runat="server" CssClass="size6 0button"
Width="60px" Text="Back" CommandName="Ba ck" CommandArgument ="btnBack"
onCommand="Comm andBtn_Click"></asp:button>
Sub CommandBtn_Clic k(ByVal sender As Object, ByVal e As
CommandEventArg s)
End Sub
Am I missing something?

Greg, you omitted CausesValidatio n=false. You said you don't want to
validate.
Validation will not fire unless Page.Validate() is called. On buttons that
have CausesValidatio n=true, they internally call Page.Validate() just before
calling their Click event. Its actually called within their OnClick method.
All other times, you must call Page.Validate() yourself. So if its
validating, its due to the control having CausesValidatio n=true.

When I opened the properties of the printer driver I could see it listed -
as Custom.
Then I had to change printer drivers. (Long story, rather OT.)
When I displayed the report, it was formatted for a full page -
not real useful for mailing labels.
The list of available page sizes did not include Custom.
