You need to figure out what part is slow and then change it...

Are you trying to load huge data to the page? In normal operation the default timeout should be sufficient.

In a particular page, you can temporarily adjust the script time out using

long currentTimeout = Server.ScriptTimeout
Server.ScriptTimeout = NumSeconds 

//do what ever you want

Server.ScriptTimeout = currentTimeout

alternatively you can change your web.config to set longer ScriptTimeout. This can be done at IIS level too.

I think you can set the datasource of a crystal report to a dataset file.

Try googling dataset and crystal report data source.

Create a serializable object. Before the page closes store all the information in that object and store it in Session.

Then you can reference the session object on the parent page. Also, put code in the parent page to set the session object to null when you are finished with it.

you need javascript to capture the closing of window. The DOM has onunload event you can attach a function to

< body onunload="performClosing()" >

Then you need to write js code to do what ever you want.

Re: how to detect the event of closing of a child page by a parent web page in asp.net

9-Apr-09 10:40

you need few things. First off, you need fair amount of javascript code.

I am assuming you know how to open the link in new window. In the new window page

add onunload to your html body tag, so it looks like

<body onunload="performClosing()"></body>

then you will need to write a code for your method

function performClosing()
{
  alert('inside performClosing....');
}

finally, you said you want to open the link only once, for this you need onClick event, in that you need to disable the link, then when you close the popup you need to re-enable it.

well, what you want to do is seems doable to me, but that involves a good deal of code.

here is how I would do it. In the page A, you need to track which items are selected (have their corresponsing info showing in B). FOr this I will keep an array and set the state as I open the link in B. When B is closed, I listed to the onunload event and return back A a status through window.opener. The rest is straight forward.

hope this helps.
