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.
View 3 RepliesI am using Linq to SQL. I have a table with a uniqueidentifyer column.
I need to insert 1000 records, each with all the same values except for the uniqueid field.
I know the syntax to insert a single record for example where dc is a DataContext():
[Code]....
Does anyone know how if there is a way, other than looping 1000 times, to tell SQL to insert 1000 records generating different unique ids but assign the constant values to the other columns?
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.

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?

View 3 RepliesI 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?

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
