It is feasible to Design tables or write SQL to create tables within SQL Server 2008. There are commercial tools such as ERwin ,which provides a graphical interface to create tables, implement relationships, normalise. It is an excellent feature to generate SQL script and generate databases with tables by targetting SQL Server.
I like to know what is the support with in SQL Server 2008 to achieve the same as
ERwin.
Please let me know any free tools that can be used as Add-On to SQL Server 2008 to achieve the same.
I have a datagrid with some data in three datacolumns. I have to apply sorting to two of the datacolumns. Is it possible without any datasource..

I am using a ListView and i want to get my datatables sorted by clicking table headers. I am binding my ListView to DataSet via DataSource peoperty of ListView.I donot want to use ObjectDataSource or SQLDataSource Controls.
View 2 RepliesModerators Note: THIS ISSUE IS BIG FOR ME AND EVEN IF POSSIBLE, GET THE REPLY FROM THE DESIGNER OF GRIDVIEW. I have been looking for him for long. I am really fed up with reviewing a good lot of web pages on how we can possibly customize the gridview to enable sorting and paging. So many sites have listed out a lot of information and so many guidances. But the problem is that one works out fine and the other is a burden. I really feel bad about being given the job of customizing this kind of a gridview which has no user friendly approach to it. Also, this control is rendered without the pager links inside the <tfoot> tag. I have tried the Pear Pager in php. It is that good and easy to use and compared to that, the gridview in asp.net is the worst ever control i have ever tried so far.
1. i can use the images to indicate the sorting direction
2. I can have the custom pager like
[code]
<<Previous 1 2 3 .. 7 Next >>.
[/code]
When i click the next when i am viewing the page at 3 , the pager links should change as
[code]
<<Previous 2 3 4 .. 7 Next >>
[/code]
Kindly look into this type of requirement and firstly tell me whether this is possible with the gridview control. I would like this request even to be escalated to the designers of the gridview control also, so that Microsoft comes out with a reply THAT WORKS and not the kind of stuff like surfing through a lot of links and pages and finally wasting a lot of days precious time and still breaking the head with this useless control. I have spent a lot of time in searching for a perfect way. Not writing a code that is non-standard. I am really serious b'cos I have spent weeks in customizing this control. If I dont get a solid reply atleast now, I am going to generate all the output by HTML content by custom coding.
I have a GridView whose datasource is set programatically. The sorting is also handled in code via the OnSorting event of the GridView.Since I'm stuck in crappy dotnetnuke, I've had to change the doctype of the skin to XHTML Transitional so that the AjaxControlToolkit would work properly with IE.fter doing this, the sorting of this GridView stopped working... if I remove the doctype change file, it goes back to working again.I can tell that the event is firing, but it is now unable to find the underlying DataSource of the GridView to have something to sort. My OnSorting event follows; whenever it is fired, the "Data Source not Found" message is displayed.

Using the products database analogy, i have an application using SQL Database tables, that needs to maintain list's of- applicable products for numerous different scenarios.
I reaslise a database is effectively a list itself, but ideally need some kind of list support as a table field, eg list of type "products" where I can list the primary key id's for each product - how to handle this situation using SQL databases?
i am trying to use predicatebuilder for a linq to sql query but i cant seem to get a join to another table. in my model, i have a table for applicants and another for job applications.. each applicant can have several job applications.
i expect in linq to sql to be able to do something like;
p.jobapptable.jobappdate where p is the applicant.
this isnt the case..i am trying to use predicatebuilder to search through applicants based on the job applications they have made? how`can i get linq to sql to show the foreign key relationships?
[Code].... Linq to sql doesn' support IHaveParent.ParentId map?
View 2 RepliesI have a DataSet comprised of two DataTables. One of the DataTables is further comprised of the results of two different SQL calls. I need to alphabetize the results of those SQL calls. After the seconds set of results is added to the DataTable I tried the following but the end result (displayed on the page) did not alphabetize the returned results. There was no error. Can anyone advise me please. 'programs' is the DataTable name, title is the column name.
programs.DefaultView.Sort = "Title ASC";
Dim dt as datatable = test.select()
dt.DefaultView.Sort = "col1 ASC"
for each dr in dt.rows
response.write(dr.item("col1"))
next
I had found out the sorting command is "dt.DefaultView.Sort", but why is it not working. Can someone shed a light.
when I use 'RowNumber' = ROW_NUMBER() OVER(ORDER BY ColumnName) then due to orderby Column name consume 76% usage. in such case what I have to do? I can see sorting taking much time in execution plan.
View 1 RepliesI am trying to do something I thought would be simple but something isn't working for me.
I have a DataTable that I need to sort by a price ascending, then select an 'nth' row value. The 'nth' value is the row count/10.

What happens is I get the "nth" value from the original tblDeals.
I have Gridview control which bind data from LINQ datacontext object which use store procedure. sort the gridview using LINQ datacontext object which use store procedure.
View 3 RepliesThis was a pretty disappointing moment - when databinding, using Eval("Contact.LastName") would work. It nicely evaluates the related Linq object's member LastName. If the "Contact" object is null, no error is thrown... instead the field is simply null.
However, the same does not hold for sorting - if there exists a null entry (this object does not have a Contact) then the LinqDataSource throws a NullReferenceException. This means that, if you ever have nulls on your foreign-key objects, you can't use sorting headers in the ListView.
This makes the feature moderately useless - I have to roll my own properties for every single field I'd ever want to sort on. That's insane.
I started learning LINQ, So i thought of just creating gridview with sorting and paging using objectdatasource using LINQ. So i got this link
[URL] which Brian Orrel tell us how to do using IQueryable Interface. but i have nearly 300 lines of stored procedure which joins nearly 20 tables. so i thought of creating a stored procedure and using that instead of IQuerytable.

I'm having trouble writing what should be a simple sub-query using LINQ to Entities. I have two tables: Customers and Orders that have a relation on the CustID field. Not all Customers have a record in the Orders table, while some have mutiple records. In traditional SQL, you could write the query like this: SELECT * FROM Orders where CustID IN (SELECT CustID FROM Customers) I know this could be done as a JOIN in both SQL and L2E, but my actual query is more complex (about 8-9 joins), so I am hoping to find a L2E sub-query equivalent. Something like this:

I know LINQ to Entities does not support the " IN " clause, so I am looking for something that will work in its place.

contents of one table are sorted by price,factory,model,size and ...if a want to get some sorts on one tabel, can i do that with one datasource?seems to be crazy to use one data source for each sorting.
Does anyone know where I can find some info on how to support data binding in my control? I would like to get data primarily from a sql server.
View 3 RepliesI would be grateful if someone could let me know what controls in ASP.NET (out of the box) support paging?
