View 4 RepliesI have this ListView that has a Drop Down List.Everything works fine (I think/hope) except that the drop down list are not showing its result correctly.This is the code.

The code behind consist of the page_load and the ItemDataBound

For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.
I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.
I have tried to accomplish this using many variations of the following code:
[Code]....
In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.
How can I make this work? I have yet to see an example or article out there to do what I am trying to do.
i want take a single value result from linq query
if i have :[Code]....
the variable result does not return nothing, only tostring() and similar how can i get a single result from linq query and use it in my ID variable?
I have a question which is insert multiple rows in a single insert? Is that possible?
For example:
INSERT INTO EMPLOYEE(NAME, AGE)
VALUES
(JAN, 18),
(JEN, 20),
(JIN, 23)
Using C#
I have code, something like I ask but there's an error.
Here's the code
string sql = "INSERT INTO EMPLOYEE(NAME, AGE) VALUES";
for(int i = 0; i < data.length; i++)
{
sql += "(@name" + i.ToString() ", @age" + i.ToString() + "),"
}
sql = sql.Remove(sql.Length - 1);
cmd = SqlCommand(sql, con);
cmd.ExecuteNonQuery;
I got an error of "Fatal error encountered during command execution."
The error goes here
{"Parameter '@name0' must be defined."}
I am facing a situation wherein i have to ask the user for the files to upload and save them as blob in the database. I have a single file upload control on the page and user can add as many files as he wants. When the user browse the file and click add button then the file gets added at some temporary location on the page and later on when the user has specified all the files to upload then I would like to insert all these files using a single insert query in the database.
View 2 RepliesI have a drop down with several option. I would like that if a certain item is select then a certain query will run. I read a post that
azamsharp on 12/23/03 .In that post he suggested to do:
string myProcedure = DropDownList.SelectedItem.value.ToString();
SqlCommand myCommand = new SqlCommand("myProcedure",myConnection);
while reading through the post it seems that this wasn't a great idea.
I have to insert a multiple records under the single table.So i have to execute the command in the frontend for every records.
Inorder to avoid i write the query like this
insert into table1(field1,field2) values('1','Test1'),('2','Test2');
and also i tried
insert into table1(field1,field2)
SELECT "1","Test1"
Union all
SELECT "2","Test2"
But I am getting syntax error.
How to insert a multiple records under the single query?
I'm using this code for creating and xml file out of a SQL2005 table:
[Code]....
Is there a way for me to create multiple xml files, one for every row, going by the primary key column, or do I have to create a separate query for each row?
I would also wondering what is the syntax for transforming this query into a stored procedure
I have 2 fields being displayed in a Gridview, StartTime, EndTime. I want to create a 'Time" column which shows the elapsed time in HH:MM format. (StartTime - EndTime) This was all generated with VS2008, table is pulled from an SQL Query.
View 1 RepliesI am trying to create an app which shows current time in 6 time zones (Sydney, S'pore, india, london, EST and CST).
I am having troubles handling DST, because DST starts and ends on different dates in different countries.
More over I want to make it configurable (add/remove cities from the list).
Currently I have added the cities in .config with their timezone differences (with respect to GMT).

I'm having a problem with my Linq to XML query. I'm getting the result data I want, but it's nested so deep that there must be a better way.Here is my XML:
[Code]....
I'm trying to get a list (simple string[]) of all Item IDs where Category Names contains "Other".Here is my Linq:
[Code]....
[Code]....
Here is a snapshot of my result from Visual Studio:The results I want are there ("item100", "item400", "item500"), but buried so deeply in the results var.
How can I get the query to return a simple
string[] = { "item100", "item400", "item500" }
I am trying something apart of my boundries, is there any way to disable a single intem in dropdownlist or stop the ddl change event for a single item.
View 2 RepliesI have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.
I am trying to display this query result in an aspx page.
It is very slow in loading. Here is the query. The inner query inside the outer quesry is the problem.(Please see the underlined part in the query) - (If I remove that part it is very fast.)
select
top 500
--This column is the issue
,Governing_Class=( case when exists (select top 1 tqc.class_code from
t_quote_class tqc
inner join t_quote_class_premium tqcm on tqc.class_code =tqcm.
class_code
where tqc.appid=pi.appid and tqc.class_code not in('8742' ,'8810','7380')
order by tqcm.premium_amt desc
)
then ( select top 1 tqc.class_code from
t_quote_class tqc
inner join t_quote_class_premium tqcm on tqc.class_code =tqcm.
class_code
where tqc.appid=pi.
appid
order by tqcm.premium_amt desc
)

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)
password = CType(result.GetParameterValue(1),String)
End Function

Would it be better to have a sp return multiple result sets and use NextResult() or have subsequent call to dr.execute.... () and hadle one result at a time?
To me using nextResult() on a multiresult datareader would be cleaner and easier - but it does not seem to be very "atomized". I guess I am wondering can the cost of executing multiple commands be neglected? Seems like executing multiple commands and receiving a single result set would also be easier to read/test/understand.
i have asp page. i did the connection with connection string. the query is to search name, id and phone numbers. i wand to display these data in 3 textboxs. how can i display these results in textbox.

I'm developing an app with asp.net and jQuery and I have a strange problem, I have the div(used as dialog) and a button to show the dialog, the first time I call the dialog, it shows correctly, I close it but when I try to show for the second time the background grays but the dialog doesn't show (only in IE in firefox it works fine). Is there a way to fix this? Or maybe I'm doing somethign wrong.
<div id="divAuto">
</div>
<button id="openAuto">SHOW</button>
And here's the js:
$(document).ready(function() {
var dlg = $('#divAuto').dialog({ autoOpen: false, modal: true, show: "fold", hide: "drop", width: "500", height: "370" });
dlg.parent().appendTo(jQuery("form:first"));
$('#openAuto').click(function() {
$("#divAuto").dialog("open");
return false;
});
});
I'm using "appenTo" because I'm using asp.net buttons in the dialog and it's the "fix" to get the buttons to work.
I have a query that references many tables, however the main record doesnt necessarily have records in the other tables. In my formview itemtemplate, i bind the values of the query but I'm getting an obvious error when the value is null. This is what I'm trying to do: (the field is a boolean btw). These fields are hidden so I don't really care if it gets assigned a temp value or something.
