>>>Hi everybody,
>>>
>>>I want to ask this question here as well.
>>>
>>>We have a People page which has a GridView list of all people, the search button and SQLWhereBuilder great free control from http://www.codeproject.com/KB/custom-controls/SqlWhereBuilder.aspx
>>>
>>>It also has several image buttons on the top such as View Communication Log, Create Excel List, Send Emails. Two of these buttons use JavaScript OnClick to open a new window with parameters and no code behind. The functionality of these buttons depends on having a dataset in the session.
>>>
>>>So, my colleague implemented it as always creating a dataset and storing it in the session.
>>>
>>>I believe it's too heavy on the resources to store such big object in a session just in case the user will press any of these buttons. There should be a better solution for this to create the dataset only after any of these buttons is pressed. However, since two of them use JavaScript code and no code-behind I don't see a way to solve this problem.
>>>
>>>Would you please suggest me some good solution?
>>
>>Does the Javascript open an aspx page? If so why not create the dataset there?
>>Best,
>>Viv

>Because it's a new page that doesn't know about the page that called it. It relies on ds being already in a session.

It sounds as if the new page is a generic page that just displays the information in the DS? If that's the case then I can't think of a way other than the one currently being used......
