How To Bind DataGrid To Display Only 25 Records Of A Table Having More Than 1000 Records
May 31, 2010
I have a datagrid control which is bound to a table which containing more than 1000 records. And i want to show only 25 records once a time. I have used paging in datagrid. But each time the next page index is set, query is fired again. This takes lots of time. So what is the easiest way to bound data in this case to improve performance.
I have a data grid in which I have to display around 12,000 records. Even if I do paging it is difficult to display all the records. Is there any other control or something else so that I can display all these records. Even if I make these as alphabetical also, some times I have to load 1000 records in a page which is difficult.
I am developing a web application and I am using access as a database. I would like to be displaying duplicated records only from a table. This table has three columns, column1, Column2, and Column3. Column1 and Column 2 have same duplicated values and column3 is unique. The details are as following
column1, Column2, Column3 Red park 4 Blue park 7 Red park 5 Yellow Cann 9 Yellow Cann 12
Now I want when I run the sql I get the following results;
Red park 5 Red park 4 Yellow Cann 9 Yellow Cann 12
I have two tables and I want to display the second one based on the primary key:
the first table is tbl1 (id,fName,lName), and the second one is scnds(id,course,tbl1id).
I am practice using MVC 2.0, so I bulilt the the class repository
Then created the Studentcontroller
The problem is if I used Details method it will show only the first record, but I want to display every course that specific a student has. I don't know if the problem in repository or in the controller.
The website is over half way done and the functionality for the blog is (except for adding posts) is already implemented and working correctlyI have a SQLExpress 2008 backendBlog posts are rendered on the page with full HTML markup within a label control.
All of the above is done and working. Though I am essentially new to creating websites with ASP.NET, CSS and SQL, I am sure that I could simply carry on and make a login page with some controls that would allow me to add records (blog posts) directly to the database on the host server. However, I am fearful of doing this because I know that malicious code can be passed in this way. Also, because of my lack of knowledge, the only way that I know of to pass the code from a control to the database is to disable validation for the page the control is on. Without a doubt I do not want to do that.
So what are my options for getting blog posts into the database? Is it safest for me to fully create the post in html and update a copy of the database that resides on my local machine? If I do it this way, how can I merge the records from the database on the local machine with the records on the remote server?
i have a question regarding grid view. i have done almost all work i needed. but one thing i want to do is i have set 4 of page size of grid. so when i show records on the web page i want to set a iframe after first two records then iframe and then two more records like i have shown in the example image. i have used LINQ with C#.how to do it. if you people want i can show you my code.
I have a table which have different records in it, When user click on each record I save the primary key of the record to another table (recent viewed) with short date and time. It checks first if that record is already there so it just update the data and time but if record is not yet there then it will add it.
I want that the recent viewed table only store 15 records in it. Not more then 15 and most oldest added record should be overwrite. Is that possible in MS SQL server 2008?
im tryin to create repeater from code behaind using C#. The data bind is working good, im tryin to put some pager. the pager is half working. i can see the pager links at the bottom, i can see the the code split the records to 10 lines each page as i set it but when i click the next link the records stay the same it wont changing for the next 10 records. my code
i have 500 records to show in webpage. i am using DataList in that webpage. if i use direct binding it is slowing down the performance of the page and is taking time to load. now i have used update panel and i want to append data records by records(i want to append as first 50records and then next 50 records something like)
I have an Access 2010 DB that I have a table of RAW data in. In my scenero when table 'a' has been populated all the rows with the updatedate of Now() get moved to another table... the SQL is like this...
As you can see it is a very simple query but it does NOT return any rows. There are actually 404 rows with todays date in teh Append_Date column.
I have two tables for storing language translations - tblEN and tblES. They have the same structure which is nvcEnglish and nvcLocal - both nVarChar fields.
In nvcLocal of the Spanish table, I enter the Spanish translations of words and phrases used within my app. Problem is, when I add a bunch of new records to the English table I also have to go in and repeat the data entry into the Spanish table. I am wondering if there is a way to import the newly added records into the Spanish table using Transact SQL?The plain language query would be something like:
If the data in tblEN.nvcEnglish does not exist in tblES.nvcEnglish then insert a new row into tblES with the values from tblEN
I am having some issues with the performance. I am binding a Gridview with around 200 records and it is taking a long time. At one time I only display 10 records on the page, but I bind all the 200 records.
Generally what is the number of records that should be bound to a gridview ?
