I have a datalist and now i want to give custome paging to that datalist using multiple active result set. I mean i want to show paging as
first,previous,1 2 3. . . next, last.In this I want to get only 3 pages at a time. and once i got the page, I want to put it in caching and again if user click on that page number then i dont want to get the data from cache instead of hitting the database
I have a complicated report that nests six deep and so really hits the database hard. I want to use SqlDataReaders NOT DataAdapters and DataSets because I don't want big tables in memory.
MARS can get me the data fast, all from the one connection. But all the examples show it binding to a treeview.
I want to bind it to nested GridViews (six deep!).
Any examples of MARS binding to nested gridview/list/repeater controls of any kind?
Would it be better to have a sp return multiple result sets and use NextResult() or have subsequent call to dr.execute.... () and hadle one result at a time?
To me using nextResult() on a multiresult datareader would be cleaner and easier - but it does not seem to be very "atomized". I guess I am wondering can the cost of executing multiple commands be neglected? Seems like executing multiple commands and receiving a single result set would also be easier to read/test/understand.
I am working on a site in which as user logs in (first database request) the stored procedure varify password and user id and then returns user record that I put in session to use next.
After this I do a second db request. it returns addresses of user which I put in cache.
I can get both sets of data (user record and his address from 2nd table) in one database requests.
I have a form where the user enters their first name, last name, email address etc.. and then they also have the ability to enter 'cottages' that they are interested in viewing (ie. The cottage name, cottage address). The user then needs to be able to 'save' this somewhere and enter another cottage into the same form.
Finally the user will submit the form, and all the user details, and cottage details will be emailed to admin.
Just after some advice I have a stored procedure that returns several tables. I then need to loop through the tables and create dynamic gridviews using the data. At the moment this stored proc is called using

i have several different sqldatasources on my .aspx page which are linked to my gridview. so sqldatasource1 - when the btn "all" is clicked displayed all the records in the gridview, if another button "btnsearch" is clicked it displays the records based on the query passed in to the gridview. i have paging enabled on the gridview but when i go to the second or third page, i have to double click the number before it displays the records, how do i get the paging to work with a specific datasource depending on if the user wants all the records to be displayed or just part? , the datagrid loads up with all the data on rendering.

I am using a sql stored procedure which returns multiple result sets. By default Sql Datasource is binding the first result set to gridview. I want the second result set to be binded. I browsed all the properties in Sql datasource but could not find one to set this.
View 4 RepliesI have a C# website developed with Visual Studio 2008 with a SQL backend. I have a top Navigation menu that has seven different tabs. I have a specific right bar content for each of the seven tabs. The content for the right bar is stored in a sql database and will be accessed using data sets. I believe that I have two ways to display the information with the data set...
1. User control - Create a User Control for each data set and then drop that on to the respective pages.
2. Master Pages - Create a Master Page for each of my seven sections, adding the data set to the respective Master Page.
Is there a preffered approach to achieve my goal? I am thinking Master Pages would be the most efficient but not certain. Is there another method I should consider?
I have a following scenario - A use selects criterias from a webform (C#) - a result is then returned from the sql. Say, to start, there are 2000 data returned from the sql and are stored in a dataset.
Now, the user wants to choose a number of drops (up to 6) - with the number of drops selected, they can enter their own quantity in each box. So, they can divide the 2000 records into 6 different drops. With each drop, there is campaigncode created based on the mail date and the job number they provide.
So, now i have the 2000 records in a dataset. What i want to do is loop through the gridview where the user fill out the quantity depending on the number of drops (for ex: if they say 3 drops, then there will be 3 rows in gridview with 3 quantity box to fill).
In the loop, I am getting the quantity, dropdate and the job number. The Campaigncode is created as well. Then, i am looping through the datarow in the dataset; updating the Campaign Code column with the CampaignCode for the number of records thats set in a loop. It works but the Campaign Code is not populated for the next set of records.
Here is the code:

I think its this line right here thats causing the problem. But i don't know how to tweak this so as to accomplish what i want to do.
if (Convert.IsDBNull(DSAEFile.Tables[0].Rows[i]["Campaign Code"]))

that say that the tables must be similar to be able to merge them into a single datagridview. I know that datagridviews only like one table at a time, but I was curious if anyone had found a way to merge two dissimilar tables to one datagridview or not.
Is there a way to use the GridView paging and having the links not use JavaScript. So that when you click on the page number 5 (for example) that link is a hyperlink.
View 3 RepliesI'd like to implement a custom paging template for my formview that displays numeric paging as well as next/previous buttons. The pre-defined templates only appear to have numeric first last as an option. Can anyone recommend a good article that covers this?
View 2 Repliestrying to merge two sets of data from a SqlDataAdapter and an OleDataAdapter and then populate a gridview on a button click. If I run just the SqldataAdapter on its own the grid populates as expected. This also applies to the OleDataAdapter. The problem arises when I try to merge the two. I get an empty table, hence dt3 is not populating. The code i'm using is below.Does anyone know why this doesn't work?

The website I am working on has a section where users can search for content they have digitally subscribed to. way to cross-check both data sets, the first being content that matches the search criteria, the second being the content the user has subscribed to. What's making this is a mess is how the data is structured. Here is an example...
We store all of our content in a "Content" table in our database. A piece of content, a "journal", for example, and all of its child records (volumes, issues, and articles) are all stored as records in the "Content" table, each with a ParentId of its corresponding parent record. So, A journal can have n volumes. Each volume can have n issues. Each issue can have n articles. A user can have a subscription to any of these, which would implicitly give them access to all child records. For example, if a user was subscribed to a journal, they would have access to all of its volumes, issues, and articles. If the user was subscribed to an issue, they would have access to all of its articles, but not the parent volume or journal.
Some users own over 30,000 records, and we have over 100,000 content records in the database. The Content table has relationships with several other tables that are used for the search. This leaves me with an expensive query to find what the user has access to, and another expensive query to search through all of the records to find search criteria matches. Some of our searches take 20-30 seconds and I would like to speed it up to a max of 5sec per search.
I tried running a query to get the ContentIds of everything the user owned when they first visited the search page, and then caching it to eliminate further database hits, but when I passed the list of ints into the query via a linq .Contains statement, I hit the SQL parameter limit of 2100, since apparently .Contains() splits them all out.
I have a page in which i need to show data in the form of a grid. Each row in the grid is made up of 2 sub-rows, the first sub-row consists of a dropdown, a textbox & a textarea. Whatever is entered in these controls should be displayed in the second sub-row in the form of labels at runtime (i.e. using javascripts)
There can be multiple rows like this. The grid would have a max of 30 row, not more than that. create this which one would be better, in terms of performance & complexity, a GridView or a DataRepeater?
I am working on a large project where I have to present efficient way for a user to enter data into a form.
Three of the fields of that form require a value from a subset of a common data source (SQL Table). I used JQuery and JQuery UI to build an autocomplete, which posts to a generic HttpHandler.
Internally the handler uses Linq-to-sql to grab the data required from that specific table. The table has about 10 different columns, and the linq expression uses the SqlMethods.Like() to match the single search term on each of those 10 fields.
The problem is that that table contains some 20K rows. The autocomplete works flawlessly, accept the sheer volume of data introduces deleays, in the vicinity of 6 seconds or so (when debugging on my local machine) before it shows up.
The JqueryUI autocomplete has 0 delay, queries on the 3 key, and the result of the post is made in a Facebook style multi-row selectable options. (I almost had to rewrite the autocomplete plugin...).
So the problem is data vs. speed. Any thoughts on how to speed this up? The only two thoughts I had were to cache the data (How/Where?); or use straight up sql data reader for data access?
I have gridview with 3 columns and one textbox in each column. My requirement is when i paste 3 cells of copied data from excel to textbox in first column of gridview automatically 2nd cell data has to be pasted in textbox of 2nd column and 3rd cell data to textbox of 3rd column of gridview. How can it be done and can anyone provide the best code.
View 3 RepliesI have two textboxes,one is for fromdate and another one is for todate. I have one more textbox for the question for the quiz(my application)For example in my database : From date is 12/8/10 and To date is 20/8/10.Now i want to restrict the user to edit the question if the quiz is already started.
Lets say today is 12/8/10. If the user comes tomorrow i.e; 13/8/10, he could not change the from date. I tried to disable the date if the date entered in textbox is < todays date. I dont know whether this one is correct or not.
I have added a datagrid where the first column is all checkboxes. I have a title in the header for the column, but right below the title I'd like to have a linkbutton called "[Check All]". I know I could simply but the button above the grid and loop thru the grid, but I was wondering if it was possible to have a link button WITHIN the grid itself in the header section? If so, how can I go about coding this?
View 2 RepliesI need paging like first 2 3 4 5 Last
I am using the grid view feature to in this way but its not reflected on gridview.
I have a table that contains a date column along with others. I need to extract two sets of data from this table for two different time periods. Call them Current and Previous, so that I can compare them line for line. There are exactly the same number of days in both time periods.
The problem is that I need to return the data like this:
CurrentDate, Count(CurrentItems), Sum(Amt), Count(PreviousItems), Sum(PrevAmt)
JOIN puts the data into the result vertically, so that doesn't work. So far, I have not found a method that will arrange the data correctly.
I have two AccessDataSources each returning one row.
I want to use the data in each row to populate content on my page, so I figured I would use a [Code].... or [Code].....
However, I would not necessarily want the labels bound to a particular DataSource placed together.
For example, I might want labels from the following columns in order [Code]....
