DataSource Controls :: ObjectDataSource Sorting And Paging In Gridview Using LINQ Stored Procedure Methods?
Jan 31, 2010
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 want to have a paging mechanism. Its a bit hard to show all data and tables for this query but this is the current resulset.
As you can see Id has several duplicate entries (EventId as well but thats as its supposed to be):
Rownum EventID Id UserId
1 22 10 03088B17-36B2-425C-BD08-13E63AF07254
2 22 10 03088B17-36B2-425C-BD08-13E63AF07254
3 22 11 39E49E5A-7A42-43B6-882C-B22EE4C0922A
4 22 11 39E49E5A-7A42-43B6-882C-B22EE4C0922A
5 22 12 15C405BB-BD9A-4C6A-BF21-A95763FAD613
6 22 12 15C405BB-BD9A-4C6A-BF21-A95763FAD613
7 22 13 15C405BB-BD9A-4C6A-BF21-A95763FAD613
8 22 13 15C405BB-BD9A-4C6A-BF21-A95763FAD613
9 22 15 00000000-0000-0000-0000-000000000000
10 22 15 00000000-0000-0000-0000-000000000000
Now, I want to have paging and I'm doing that like this:
[code]...
In thew above query, when I leave out seltion of the RowNum column (so instead having: "SELECT distinct eventid,id,userid FROM") only 3 records are shown when I have a maximum pagesize of 5 passed to the @maximumRows variable.
What can I do to have exactly 5 records shown?

on my WebApplication I have GridViews filled with a LinQ-Query. Like this
Dim teamA = (From t
In datacontext10.T_TEAM
Where t.group =
"A"
Order
By t.sort)
GridViewA.DataSource = teamA
GridViewA.DataBind()
Now I want do enable automated Sorting and Paging? How could that work? Could I use a ObjectDataSource? Which control could do that for me?

I am having problems returning a string value through a stored procedure/linq to a label. Everything works fine if I return an integer value but I cant get a string value to bind to a label. I get the error message
Microsoft.VisualBasic.CompilerServices.Conversions.ParseDouble(String Value,
NumberFormatInfo NumberFormat) +201
Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger(String Value) +66
[InvalidCastException: String "System.Data.Linq.SqlClient.SqlPr" to 'Integer' is invalid‚]
This is the stored procedure
ALTER PROCEDURE test
AS
Select ProductName
From Products
This is the vb page
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim db As New DataClassesDataContext
Dim product As Integer = db.test.ToString
Label1.Text = product
End Sub
This is the aspx page
<form id="form1" runat="server">
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
</form>

I have an application where depending on what the user selects run a different stored procedure.
I am using LINQ and am passing the stored procedure name into a sub that will run the stored procedure and return values that I am loading into a DDL.
For example I want to pass the procedure name "GetProducts_Hats" to the sub and not hardcode it.
Protected Sub LoadParamDropDowns(
ByVal SqlObjToExec
As
String )
I am passing the storedprocedure name in parameter SqlObjToExec
so instead of
values = mydb.GetProducts_Hats
I want to code it to be a variable
values = mydb.SqlObjToExec
But the above code does not work.

It has been more than 2 days since I had started searching for the answer and I still don't know how to do it.
I have empty gridview that is filled with data depending of the parameters given. The gridview is used to track changes user had made to the database.
In the first dropdown list the user selects from which table (or all tables) to display the data. From the second dropdown list the user selects from which column (or all columns) of the previously selected table to display data. In the first textbox the user enters the search term and in the third and fourth textboxes the user enters the date range in which the changes occurred.
After clicking button the data within the given parameters should be displayed. The problem is that data is displayed fine, but I can't manage to get sorting and paging to work so if possible, give concrete answer because I'm pretty sure I googled one half of the web during these 2 days. :)
Here is the code for the .aspx file:
[Code]....
Here is the codebehind:
[Code]....
To sum everything up... My question is: "How to enable sorting and paging for this code?"

Initially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?

Moderators 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'm creating an ASP.net website with 3 layers (Presentation, BLL and DAL).
BLL and DAL are 'class library'. DAL has a typed dataset. Presentation refers BLL and BLL refers DAL.
I wanna populate my GridViews with ObjectDataSource, but it only shows me the DAL. Nothing from BLL...
What am I doing wrong?

I'm coding a report page.In this page,there are two date fields for user to filter the date and the GridView is filled depending on these dates in the CodeBehind (When user click the button view).Now I want toimplement a paging/sorting feature for this GridView.I've researched and see there are default paging for GridView which is not very efficient (my report table may have thousands of records) and custom paging but this requires using ObjectDataSource (which I don't use).Thus anyone can recommend me some approaches that are best used in this situation?

am having trouble figuring this one out. Am using stored procedure and using databind for the gridview . i got the codes off other sites. I'm guessing its the code that i've underlined, how or what do i use as the datasource for the sorting event. I used the Session for the paging event and that works but not for sorting.

Can we specify two different methods as SelectMethod of ObjectDataSource at two different events?
I need my Objectdatasource to get filled with one method while at button click event I want to fill it with other overloaded method.
Both the methods have same name and return same data type but they have different input parameters.
