how can I build 'compiled query' includes lots of paramters. Example. I use only one parameter in this code.
[Code]....
How can I write a query that it can takes lots of dynamic parameters and dynamic conditions.
how can i bind data to gridview when using compiles query?
load all country

In a website, if I have a class:
[code]....
How many times the query will be compiled? Every time the page loads...? Once in the application...?
1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.
When using parameters in an ObjectDatasource for an RDLC report, how can you get the parameter values and display them in the report?
View 1 RepliesI have SQLDataSource for my gridview. By default it works fine but i need to determine a few things before calling my procedure. By this i mean i need to determine a few things about the fields completed and set a flag to determine where the procedure will look.
I found a few examples online on passing parameters in code behind, but cant seem to get them to work. Here is what i tried and cant get results back. When i execute the procedure on the SQL side with the same parameter values, it works, so i know its returning results, so means my values are not being sent or im doing something really wrong. I have some of the lines commented out so the page can load and display for now.. but i need to get it working with custom parameters and flags.
Here is my SQLDataSource:

here is my code for selectiong some records from db table
string strSql = "select * from mtblNBD where SentTo=@SentTo and InternalStatus Is NULL order by DeadLine desc";
SqlCommand com = new SqlCommand(strSql, con);
com.Parameters.Add("@SentTo", SqlDbType.NVarChar, 50).Value = (string)Session["uname"];
here I am using parameters for SenTo field but not for NULL so it is ok... or should I use parameters for this field where value is NULL , if yes then how can I use parameter for this
I want to dynamically populate a link with the URI of the current request, but set one specific query string parameter. All other querystring paramaters (if there are any) should be left untouched. Eg, imagine I want to build a link back to the current page, but with the querystring parameter "valueOfInterest" always set to be "wibble" (I'm doing this from the code-behind of an aspx page, .Net 3.5 in C# FWIW).Eg, a request for either of these two:
/somepage.aspx
/somepage.aspx?valueOfInterest=sausages
would become:
/somepage.aspx?valueOfInterest=wibble
And most importantly (perhaps) a request for:
/somepage.aspx?boring=something
/somepage.aspx?boring=something&valueOfInterest=sausages
would preserve the boring params to become:
/somepage.aspx?boring=something&valueOfInterest=wibble
Caveats: I'd like to avoid string manipulation if there's something more elegant in asp.net that is more robust. However if there isn't something more elegant, so be it. I've done (a little) homework: I found a blog post which suggested copying the request into a local HttpRequest object, but that still has a read-only collection for the querystring params. I've also had a look at using a URI object, but that doesn't seem to have a querystring
i need create query dynamically in my .cs page. Actually what happens in my application is user can pass the column name and Table names from the page. by using those parameters(columns and tables) we need build Select query . we need retrieve those values from database and show in text format to user.there may multiple table and single table have multiple columns also.

I am building an invoice system for a client and I am having trouble with the web forms related to the INSERT new order query.Basically I want to build up the order query from the selections made and then store it all in db at the end.
I don't want to use temporary db storage because it's a wasted trip to the server, I don't want to use session state because it's not data about the user I'm storing.... Unless I'm wrong, from what I've read I think query string is my best method since the data is not sensitive, it will just be primary keys and the like.
On the first form, the user will select the customer id from a datagrid displaying all customers. The next form allows them to choose the product from a datagrid showing all products and so on.... How do I pass this information across several pages?
My hope is at the end I will be able to take all the values and insert them into the corresponding tables to make up the customer order.
I know that it is basic questions, but I am stuck here.

I am trying to set up a page that has two behaviors. I'm seperating them by URL: One behavior is accessed via /some-controller/some-action, the other is via /some-controller/some-action?customize. It doesn't look like the Request.QueryString object contains anything, though, when I visit the second URL...I mean, the keys collection has one element in it, but it's null, not 'customize'. Anyone have any ideas about this or how to enable this. I'd like to avoid manually parsing the query string at all costs :).

SELECT p.Profile_Id

I am new to MDX and Sql Server Analysis Service and I've searched this high and low and read a lot of articles, but cannot figure out how.I know this is tough after reading so many articles online, and thus I am only trying my slim chance of getting something helpful from here. I need to create a sales report and want to parameterize the region, so, I'd like to have something likeSELECT blah blahFROM [MySsasWarehouse]WHERE @regionThe @region may take values such as [USA].[Northeast].[New Hampshire], for example.How do I make this happen with MDX? I learned that I can doSELECT blah blahFROM [MySsasWarehouse]WHERE STRTOMEMBER('[USA].[Northeast].[New Hampshire]')But, I have no idea how to have something like STRTOMEMBER(@region)and to be able to pass values to that @region variable.
In the end I would like to create a SSRS report using this MDX query and pass different values to @region. Do NOT point me to articles about how to pass parameters to SSRS, because I know how to do it through the URL query string.My question is How to create parameters for MDX query per se, and I haven't been successful in attempting to do so.
I have an update command with variables, is there a way to see the query after the variables are set?To see the full query as it sends to the DB. (i know in Java hibernate you could add some log file)
View 2 RepliesI am trying to redirect the user to login page with ReturnUrl and with querystring parameters which are already in the url there.But it is getting only first querystring parameter and not others. here is the code:Response.Redirect("~/login.aspx?ReturnUrl="+Request.RawUrl);it is showing correct in login.aspx after redirect but not returning as per querystring parametersI ave also tried other methods e.g.:
Response.Redirect("~/login.aspx?ReturnUrl="+Request.AppRelativeCurrentExecutionFilePath+"?"+Request.QueryString);
In one of my ASP.Net websites, I have to provide a link to the user in which all query string parameters should be encrypted.What I am thinking is to use the command "aspnet_regiis" (as used to encrypt web.config data), pass output as a query string inside published url.When the user clicks that link, I first decrypt the string and then fetch the original data for the query string.Am right in doing this? Is there any good technique to encrypt and decrypt query strings?
View 4 RepliesI am trying to show a Gridview that lists information in a database based on a query. The query takes a parameter of a string, how do you define what this parameter is. An example of the screen I am stuck at is:http://static.asp.net/asp.net/images/dataaccess/07fig08cs.pngAn example of the code i want to use is:parameter for my object data source select query = OBDS_Query_ParameterOBDS_Query_Parameter = str;
Sorry Im not sure how to explain it...For instance if I have a query that GetAllProducts(String userName); How do i pass or define what userName is when using the data gridview. I am using an Object DataSource and linking the data Gridview to that. I can do this without the object data source and strictly melodramatically like this:
quartz_SongsTableAdapter songsAdapter = new quartz_SongsTableAdapter();
CurrentRole = "admin";
GridView1.DataSource = songsAdapter.GetSongForClient(CurrentRole);
GridView1.DataBind();
with query parameters in ASP.NET. For example, if I have query:

for parameter @id I intend to use combobox. Everything is just fine with this example, problem begins when I try to use IN clause.What I need is query like this:

I am using LINQ-to-Entities and here is my query
public void SomeFunction(string searchField)
{
var data = from a in dx.SomeTable where [code]...
Now if I had to use the value of the parameter "searchField" as the property to be selected in the where clause then how do I do it ?
i.e I want to assign the value of the parameter "searchField" to the property I am checking in the where clause.
So ... the value of "SomeProperty" in a.SomeProperty must be the value of "searchField". How to do this ?
PS : I dont want a.SomeProperty=searchField. What I want is "SomeProperty" itself to be replaced by the value of "searchField" and then , this has to be checked to see if its equal to 270.
I have a GridView bound to an DataSource query with parameters tied to form controls.What is the standard / best-practices way to handle optional query parameters?
View 3 RepliesI have an application which uses globalization, hence the datetime objects are globalized based on current culture.

View 1 RepliesI have an asp.net site which includes a "search" page that queries an SQL table, then redirects the user to a "results" page where the results of the query are displayed.
