Caching Gridview Data In Session?
Jan 28, 2011
I have a reporting page with a gridview and a calendar. When the user loads the page, the default date is today and when he clicks on a date in the calendar control, it loads the reporting data for that day. Each user has a different report and the data is between 300-500 rows per day. At the moment, I have a linq query that returns the data for a day in the form of a list. Given the relatively small amount of data per query, I'd like to store the result of the query in the session so that I can do the paging and sorting from the session, without going back to the data store.
What I'm looking to do is a list of lists so that when the query loads, the data is saved until the session times out. For instance, if the user selects 4-5 different dates, each of these queries is saved in the session and then if he clicks on one of those dates again, a function first checks to see if the data is in the session: GetQueryFromSession( DateTime TheDate). I'm stuck on this. How do you create a list of lists that works with the session object.

have an ObjectDataSource with the following configuration:
[Code]....
And the 'Select' parameters will aid in making a 'unique' combination per user selection to populate the GridView it is bound to:The problem that is occurring is that GridView search results are indeed cached, but the cache is a little too public and shared between all users currently running the application. So if user1 creates a search that populates the GridView with 100 results based on some unique dates and CategoryID, and then user2 in a separate browser does another search with different dates and a different category

in my web appliaction there are many pages which use data from backend . and all these pages run according user login in application.every user gat different data according data availability for particular user .And data is not static for user in database it can be update ,delete,and may be new data inserted for user, frequently . in this case roundtrip for data on sql serverv increased and it cause of load on sql server. in this csae i want to implement caching on my pages. But I am not able to do this because i have no idea about how implement caching on the basis of particular user data .

Background of what I have implmented so far:
I've used datagrid view to show a list on records on page, the list contains huge number of records so paging was required. Since the amount of data was huge it was not advisable to bind the grid with complete data. So, I used custom paging and tweaked the sql statements to get page wise data. Now whenever user clicks next or previous data for current page is fetched from the database and gridview is binded with that much data only.
Now I had to add a checkbox column to the grid so that user can select multiple items on multiple pages and perform an operation (for example send email to selected people in the list). I achieved this by making a template column with checkbox control and keeping a boolean column in the datatable which is binded to the gridview. I've also kept a collection selected checboxes so that the state is maintained on every postback.
I've also used ajax so that user cannot see postback happeneing. Everything works just perfect.Here comes the problem:
Now say I have 5 pages of data to be displayed. I select 3 people from first page and move to next page, this will cause fresh databinding and previous data will be lost.Now I go on and select 3 more people from page 2Finally press the send mail button What is expected here is that the mail should be sent to 6 people but details of only 3 people are available because grid is rebinded.
What is the best way to cach data of selected rows in this case. The number of columns is around 20 out of which I show only 10 columns on screen and others are kept hidden. The values of hidden columns are used while sending the emails.

I've this Gridview of tasks a Hyperlink TemplateField that takes the user to another page where he can accept/reject[buttons] the very task , on clicking accept/reject[buttons] the page redirect the user again to the tasks Gridview , unfortunately , the same task is still there unless if the user manually Press F5[Refresh] I tried the following nothing worked
1- EnableViewState ="false"
2- In the ObjectDataSource , EnableCaching ="false"
3-i tried to use Ajax but it gives me a whole lots of errors from the webconfig ,my website is working ,I can't stop users from accessing my site in order to wrestle with Ajax
the approach I am taking on developing my site is to work in my local machine when I am finished with my changes I literally Copy/Paste the new aspx/aspx.vb overwriting the old file with the new one , this approach is working fine but it causes the server to a bit slow esp. in the first time after change, is there a more Professional way?

I have webpage with three dropdown boxes on left side (Country Dropdownbox, State Dropdownbox, City Dropdownbox) and these dropdown works independently or one box will depend on another. I have a gridview in right side and the results will be binding to the gridiew by selecting the left side dropdown boxes.
I need to implement the caching technology here because the web page loading very slow due to large amount of records. For example if i select any country from the first dropdown box and the other two boxes are default (Selected text is "ALL"), then It should display records related to selected country in gridview.
Further if I select country and state from the respective boxes then it should display the related records in the gridview like so on. Now i want do some caching functionality to improve the performance. I tried caching the Dataset while binding to gridview but in my case the results will not be static becasue user every time will select different options from different dropdown boxes and results will come based on the selected options.

I am trying to speed up a Gridview on my page that reads 8,000 records using an AccessDataSource. So I am trying to implement caching. I have used the information given here: [URL] but it has made no difference in the response time. Can anyone direct me on this? Is there something you have to specify in the gridview (besides the datasource). Would it work if I went to SQL Server?
This is my AccessDataSource code. You can see the 3 relevant lines starting 6 lines from the top.

I have 2 gridviews on a webpage that are fully editable. I also have a button, that when clicked, runs some SQL in codebehind to insert new rows into a data table. The gridview should then update with the latest results of the SQL query, which is does.
Then the user clicks on to the next page to do the next thing.The problem is, when they go back to the first page, they're still seeing the old, non-updated data. I've run the SQL from the page manually on the server, and the new data is there, but the GridView doesn't want to pull it.

I currently have a control that called MyGridview that inherits Gridview. It has a paging template within it for customized paging options, and I'm at the point where I want to cache the initial datasource for better performance. I haven't done this in a long time, so perhaps there is a different solution these days with the newer frameworks. Before, I simply used a Cache object that was named whatever the gridview was named. I couldn't use the same gridview name through the application though. Is there a best way to have a cache object, or some other object like a session within the control to store those unique datasets for paging and sorting?

We store the location information in a table. Numbers of records are over four thousand. This table structure is self-recursive. In our web project, we use dropdownlist control to populate all these locations. We got performance slow problem. So googling about Caching, we consider to use Data Caching with Sql Dependency. However, not found yet a full-covered sample in .NET 2.0 and SQL Server 2005 or 2008.

My web application is using the asp.net cache object to store data from the database. I am looking for an elegant to invalidate cache objects but haven't come up with anything elegant yet. It is easy to invalidate a single record or a list of all records in a single table, by keeping track of their cache keys. However I may have any number of lists of subsets of a table's data. I would like to invalidate only the cache records of the lists that contain a particular record, when that record changes. I don't want to have to invalidate all the lists of data for that table if only one of the lists contain that record.
