I know how to use UpdatePanels and so on but I would like to know if its possible to run method on the server (after clicking a button) which doesnt change anything in controls on the site but for example updates database.
I know that I can use WebService but is there any way to use simple code behind methods ?
I have a requirement where a user logs on to a server where exists a website. The user bring up the site on a browser on that server and loads a power point presentation slide. At that time, users using their laptop clicks on the link to that site and sees that particular PPT slide loaded on the server. Then the operator/user on the server clicks on the second slide and the laptop would now see the second slide. Is this possible to do? If yes, then what technology to use? DHTML? or something else.
View 4 RepliesI'm trying to show some data in the update panel refreshing every second using page method. Everything works fine until I introduce Session. As soon as I save some data into the session my Ajax Page method is not called every second. Here is the complete code

why after clicking "Enable Session" button refresh stops working?
I have a large DataTable cached in my web app that is the result of a complex query that returns a large data set. Whilst this data table is cached the query that runs to "refresh" this cache still takes a long time, largely due to the sheer amount of data being returned. In order to speed this up I am considering implementing a timestamp type approach to my tables in order to limit my query to only return rows which have changed.
I then intend to merge this smaller dataset with my cached datatable. Has anyone done anything similar to this, or is there anything out there that handles this already? I feel this could be a re-inventing the wheel situation if I dive straight in.

I am using a dropdown, a devexpress grid view and a button on my page.
My gropdown contains the months in the format MM/YYYY, and on dropdown's selection change the data binds in the grid view.
the functionality of button is to go on previous page as same as back button of browser.
Now, my prob is that if i select any month and then select another month, the data changes.
but now when i click on back button having onclick ="history.go(-1)", changes the data on the grid view but the month in the dropdown remains the same.
For example:
Suppose, first i have month selected as 02/2010. At this time the data in grid view is for exapmle 01234
now when i select month 03/2010 the data in grid changes to 56789
now when i click on back button, then data in grid changes to 01234 but the month in dropdown remains to 03/2010.
Code below is ready to test: MVC3 Problem is when I enable e.preventDefault(); than individual errors not popping up infront of each control generated by ValidationMessageFor and showing up when e.preventDefault(); is enabled.

[Code]....

I always use SqlConnection() To open a connection then use the connection to interact database. But I have heard somewhere that opening SQLconnection() take a time. and if on different pages of projects I repeatedly Connect database then It will take long access time always. So I want to know that if there is any other methods which don't use the SQLConnection to interact database and increase the response time of database.
View 1 RepliesI am not sure how to explain this but I will give this a try. Before, we had an app running on windows XP and all the reports were working fine. Now, the app is moved to windows 2008 server. There is one report in this app that uses Microsoft Interop.Excel which is used by component one. Apparently, interop.excel is not supported in windows 2008 with 64 bit running. After doing bunch of research, we have two options - either write this report again or execute this report from XP.
I want to try the second one. The interop.excel works fine in XP. A copy of this app is on this server. What would be the best way to execute this report from windows server 2008? It looks like i would have to connect to the XP server, get access to the app and finally the function that executes the report. Is this possible?

I created a method which instantiates an Attachment using a string and calls the corresponding Delete() method for the Attachment object.
Now, I will need to pass the string from javascript function to the method I have created. I cannot use PageMethods.

View 1 RepliesI have my local Dev environment VS2K8 (ASP.NET) and our Dev server with no Dev tools. I have an app that runs just fine locally, but once I move to the Dev server I get an error. Another part of the problem is that I am moving the compiled dll for the website so I am not even getting the .cs line in the event log so it is very difficult to debug on the Dev server.
