C# - Accessing The Result Set Of A Stored Procedure, Executed Using SqlDataSource.Select?
Jul 21, 2010
I'm programming a webpage in ASP.NET which displays a list of students not listed as participants in something, and upon clicking a student name shows you a brief summary of their details, so the user can ensure they're selecting the right person.
My code currently correctly obtains their ID, adds it as a parameter to my stored procedure and executes the procedure;
[code]....
However, when I try to access the results I get the following error:
System.NullReferenceException: Object reference not set to an instance of an object.
Upon debugging, there don't seem to be any results returned... but when running just the stored procedure in SQL Server with the same data, it does return a single row, as expected.
How do I access this result so I can bind it to my fields?
(I am working in ASP.NET 3.5 in Visual Studio 2008, with SQL Server 2008.)

@ContractStateCode, @ContactZipCode @BillingStateCode, @BillingZipCode show "not a parameter for procedure SelectDonorXiD".
The Results show the selected data but the parameters are all null.
My C# ocde -
DataView dvSql = (DataView)sdsEditDonor.Select(DataSourceSelectArguments.Empty);
gives - "String[1]: the Size property has an invalid size of 0."
I understand that something is wrong with my stored procedure but for the life of me I cannot see what.

Being new to using the declarative syntax of SqlDataSource I am trying to figure out a way to set the value of a parameter to a stored procedure. I have a Client_ID that is passed via the Request Object and I need to set the Client_ID before the stored procedure of the SqlDataSource is executed.
Does the stored procedure parameter have to be predefined in the ASPX markup or can it be added dynamically in the code-behind? Would anyone have an example that demonstrates the SqlDataSource markup with a stored procedure and parameter as well as setting that parameter value in code-behind?

The following stored procedure updates the value in LeaveTransaction table.
[code].,...
My Question here:
I have written the above trigger,which would update the value for the corresponding records in another table ie) LeaveCumulative table. The trigger is not updating the value in the designated rows in the leavecumulative table. Whereas when I excute the same update command separately in the Query Editor window the trigger is working fine.

I have a MVC project that has a Linq to SQL dbml class. It is a table called Clients that houses client information. I can easily get the information to display in a View using the code I followed in Nerd Dinner but I have added a stored procedure to the dbml and it's result set is of IQueryable, not IQueryable. I need to convert IQueryable to IQueryable so I can display it in the same View. The reason for the sproc is so I can pass a search string tothe sproc and return the same information as a full list but filtered on the search. I know I can use Linq to filter the whole list but I don't want the whole list so I am using the sproc.
Here is the code in my ClientRepository with a comment where I need to convert. What code goes in the commented spot.
public IQueryable<Client> SelectClientsBySearch(String search)
{
IQueryable<SelectClientsBySearchResult> spClientList = (from p in db.SelectClientsBySearch(search) select p).AsQueryable();
//what is the code to convert IQueryable<SelectClientsBySearchResult> to IQueryable<Client>
return clientList;
}

I have an aggregate stored procedure (named sp2) that returns a count of records meeting a certain criteria ASrecCount. I am using a DAL per the ASP.NET tutorial and have created a Table Adapter (named
sp2TableAdapter) with GetData and Fill methods. I have a button on an ASP.NET page that launches an event handler. In the button's event handler, I have this line: sp2TableAdapter sp2 = new sp2TableAdapter();
What works so far:
This code will bind the value of sp2 to a data control:
sp2TableAdapter sp2 = new sp2TableAdapter();
DropDownList1.DataSource = sp2.GetData();
DropDownList1.DataValueField = "recCount ";
DropDownList.DataTextField = "recCount";
DropDownList1.DataBind();
When running this page and clicking the button, the numeric value of recCount returned from sp2 is bound to the DropDownList control and 1 row is poplated with the recCount value (in my case 1451).
Problem:
In the event handler, I do not want to bind the value of recCount to a control, but want to to use it in some logic as an integer. What is the C# code that will do this? (In place of the DropDownList control lines above)

I have a stored procedure that creates a dynamic query. Sometimes the query is not built because there are no elements in the dynamic query. When the aspx page loads the SqlDataSource throws an error that the query is malformed. How can I catch this error, and handle it with a default message, before it returns the error to the aspx page?

Using a FormView with a SqlDataSource, I'm attempting to Update data
by calling a stored proc in code behind. I was having trouble getting parameters
using Update Parameters in the SqlDataSource, but found a working solution by
coding the parameters.
The problem now is I'm getting an "Updating is not supported by data source 'XYZ' unless UpdateCommand is specified'.

I am trying to return single string result through a stored procedure and Linq. This works fine when I test the stored procedure but it is not returning the value to the page. The value returned is always 0 which is the return value. This is the stored procedure:
ALTER PROCEDURE Login
@CustomerName nvarchar(50),
@Password nvarchar(50) output
As
Select @Password=Password
From Customers
Where Customers.CustomerName=@CustomerName
This is the vb
ALTER PROCEDURE Login
@CustomerName nvarchar(50),
@Password nvarchar(50) output
As
Select @Password=Password
From Customers
Where Customers.CustomerName=@CustomerName is the code created by the designer
This is the designer function
<FunctionAttribute(Name:="dbo.Login")> _
Public Function Login(<Parameter(Name:="CustomerName", DbType:="NVarChar(50)")> ByVal customerName
As String, <Parameter(Name:="Password", DbType:="NVarChar(50)")> ByRef password As String) As IntegerDim result
As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod,MethodInfo), customerName, password)

I have a parent window parent.aspx and a popup window
popup.aspx. parent.aspx
has a confirm button which on click open popup.aspx. This popup.aspx holds a filled application form like leave application form of employees and a email sending button. That button on click send emails to the specified email addresses with attachment. The popup.aspx has a javascript function sendResponse() which call another javascript function display() of parent.aspx after sending the email. The display() function display a message by Label control regarding the email sending i.e., whether or not this email sending operation is successful. The sendResponse() function after calling display() close the popup.aspx window. I have successfully did all the aforesaid jobs.
Now the scenario is that I have a database which is holding various leave information like casual leave, medical leave etc of employees. After sending email successfully I have to update this database.It will be better to tell in this context that the email sending portion of my cs script is :
[Code]....
this info string is passed to the sendResponse() javascript function as :
[Code]....
And the sendResponse() function is :
[Code]....
Now the problem is, in which portion or when I do update the database. Should I update the database in try-catch block of email sending or from sendResponse() function?I have tried to call C# function UpdateDatabase() from sendRespose() as shown here. But this static method is creating too many problems like the popup.aspx is not closing automatically, if I try to call another C# non-static method from the static UpdateDatabase() method to close the window I have to call it by creating a new instance of that page, which is eventually not closing the popup window. Can I call stored procedure from javascript function sendResponse() and pass parameters to it? If so how can I call it?
