Executing search function in page load event instead of button click
VT Venkatesh
box & a submit button)
When the search word is entered in the text box & the submit button are
pressed the following code is executed
******************************************
if tbSearch.Text.Length > 0 then
begin
errorLabel.visible:=false;
Response.Redirect('SpiderSearchShow.aspx?'+searchWord+'='
+Server.UrlEncode (tbSearch.text));
end
else
begin
errorLabel.Text:='Please enter some search text';
errorLabel.visible:=true;
end;
******************************************
Then i want the SpiderSearchShow.aspx to display the search results
based on the search criteria when the page loads.
Though I have written the search criteria code in the page load
event,the search does not take place unless i explicitly code the search
code in button Click vent handler & click the button.
How to ensure that the code gets executed in the page load event itself.
I know i am missing some thing very simple here:)

I believe that in the page_load event, the viewstate of the controls has not
been restored. So during the page_load, your textbox has no value.
Why do you need to execute the search in the page_load instead of the
on_click?

Why are you using a redirect page? You should have the button call the
destination page directly using the PostbackUrl property of the
button.

The user inputs the search text in the home page & the search results
have to be displayed in another page (both use the same user control
with a text box & a search button) & for that to happen i need to run
the search related code in the page load event.
Is there any other way to run it?

Look at the help for PostbackUrl and the associated properties, it
should explain what you need to look at.

I tried to use the concept from
http://msdn.microsoft.com/en-us/library/6c3yckfw.aspx
I declared a property searchString in searchpage.aspx & tried to access
the property searchString in searchpageResults.aspx through
previouspage.searchString
How ever searchString property does not show up in searchpageResults.aspx
I have declared the previouspageType directive in searchpageResults.aspx

This is not something people commonly do so code completion might not
show you the properties. If you type the property in it should
compile, otherwise do something like:
(PreviousPage as SearchPage).SearchString

This is not working at all.Even (PreviousPage as
SearchPage).SearchString does not compile
Even the diective <%@ PreviousPageType VirtualPath = "~/SearchPage.aspx"
%> is showing an error 'Incomplete tag found at line 1' though this is
at line 3.when i remove the directive the error goes away
Is this a bug with the editor ?

Possibly, I have never seen anyone try to use this directive in
Delphi.NET before. You can skip the directive and just typecast
PreviousPage to whatever you need. Other solutions that might work
are:
* Add a button click event to SearchPage.aspx, IIRC, if you refer to
PreviousPage in SearchPageResults then it will cause the event to
fire.
* The article you linked to also provides a solution using
PreviousPage.FindControl

PreviouPage always returns nil in delphi.net.
I tried it in VS & it works great.How to confirm whether previouspage
works though the the word is recognised & it compiles ok.
Can some one test this out ?
