Hi All,
In my application user filter,serch items in the gridview but when he/she click the button then all item serched items he losed.
I want to disable back button.for this I m using following code
<script type="text/javascript">
function noBack(){window.history.forward()}
noBack();
window.onload=noBack;
window.onpageshow=function(evt){if(evt.persisted)noBack()}
window.onunload=function(){void(0)}
</script>
but it breaks for go to previous page but in this situation user is in same page.
thnks to all.........

As I think, the best way to disable the back button is "don't create the history of the page". Because may be in some browser's, disable code will not work.
Here is the code to remove the history of a particular page:-
<%
Response.Expires = 0
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1)
Response.AddHeader("cache-control", "private")
Response.CacheControl = "no-cache"
%>
Hope this will help you......

What part/tag of the .aspx page or (event handler) code behind does this code fits?
|
|
|
|
|
you can put this code on above the HTML tag of your .aspx page.

Thnks For Reply
I have used this code
but it is going to back......
in all browsers(IE,Mozila)
|
|
|
|

This code has to be used on previous page.
Means, if you want's to disable the "back" button of page "zxc.aspx", so you have to put this code in previous page of "zxc.aspx", from which you have come to "zxc.aspx". i.e. if you have come from "test.aspx" (on click of any link) to "zxc.aspx", then you have to put this code on "test.aspx" page.
Try this. This will definitely work in all browsers.

I require to develop a project based on crawling which can basically search as a normal search engine but instead of getting output as URLs i need the Data inside the URLs to be Generated as a file which has all the data to be pasted in it.
Is there anyway of Extracting the Google Search...
|
|
|
|
|
Google uses the URL like http://www.google.com/search?q=search-term[^]. You can construct this kind of URL with your own search term and send a request. You will get all the search results as string. Use a regular expression to identify hyperlinks from this and send request to each link separately to extract it's contents.
Best wishes,
Navaneeth

Can a java application call a WCF service?If Yes can any one help me how to do it?
I have created a WCF service in .net .
I have simple java application.
I want to use WCF service in Java application..
|
|
|
|
|
It should be possible based on how you are exposing the WCF service. If you expose it over HTTP, you should be able to consume it from any application/any platform.
|
|
|
|
|
Thank you for replying.
But I want to know how to read WCF service in Java application.
|
|
|
|
|
When you expose your WCF service over HTTP you will be able to extract WSDL and Reference map for your service. You can use it in your JAVA application just like any other classic web service's WSDL and configure it to consume the same.
My experience is close to 0 on JAVA so I'm not in a position to help you with the details.
|
|
|
|
|
Make your WCF service able to return a wsdl and confirm that on the Java application side.

Hi!
I have a Gridview that contains a TextBox that displays a Date and a Button. How can I get the Date from the TextBox and Assign it to a DateTime Property so that I can pass that to another function?
Illegal Operation
|
|
|
|
|
You need to use Casting.
Get that textbox by FindControl() method of GridView, cast it, you'll get its text property.
|
|
|
|
|
I have fixed the issue.
Basically I changed the DateTime Property to static.
Thanks for the reply's...
