I don't think so. Because after CG it was you and abhijit who were very regular in asp.net forum. A well deserved for both of you. Smile | :)

Does anyone have any suggestions for a good, web based math equation editor? Ideally it would be pure .net, but I'm open to flah or java if required.

Any suggestions would be appreciated

The typical way is to either create a bitmap in the file system and use the URL to load it in, or you create a page that your image control points to, and it takes a query string parameter to stream back the bitmap.

Mr Christian Graus,

Thanks for your response.

There is a control at the top of the page with the label Search, you might want to give that a try.

This is not an ASP.NET question, you'd find an existing library and then pass the bitmap it generates to a webpage.

Gridview sorting

Hi Friends,

I am binding a grid view using Generic List. I am using c#.
I am sorting my gridview and its perfectly working.
In my grid view I've a link button which takes user to the Details page of teh recod to view the page. working perfectly.
Problem is:

When your clicks on search button I am querying database with default order by organisationtitle.
then if user sorts gridview by post code and clicks on view detail link which takes user to the detail view page.
Now if user uses browswer button to come back on the search page gridviw automatically sorts the data by title but it should be sorted by post code as user last time click on post code to sort the gridview.

Please let me know if you need more details.

I'd suggest you need to put the sort order on the URL, so when you go back to the URL that has the initial view, the URL gives you the sort order. The other option is to use the session, but there's no need for that.

Thanks for the reply,
I found the solution.
I was using Gridview inside asp.net update panel. Removing it from asp.net update panel i got what i wanted.
I guess partial page request was an issue.

I am generating my own sessionids by overriding createsessionid method in sessionidmanager class.
Can anyone please tell me how to find out if the current request is a complete postback request or asynchronous postback ?

AFAIK , SessionID is unique and 120 bit identifier that track each and every session request. And This number is generated by proprietary algorithm . and its secure enough to reverse engineering it.
Then Why you are trying to do this ? can you please explain . I am realy interested to know . OMG | :OMG:

I have multiple nested update panels and i want to generate seperate sessionids for asynchronous postbacks and complete postbacks.
I will be using the sessionid as a key for my custom caching object and the cached object will be reused in other pages.

Also i want to generate a different sessionid when the application is opened in the second tab in the same browser. Since i have update panels in my pages, if i am able to differentiate asynchronous postbacks and complete postbacks i will be able to generate a different sessionid.
