View 10 RepliesForms Data Controls :: Chart Control Getting Numbers From GridView, But Just Duplicates?
Oct 4, 2010I have a gridview that I loop through to get the x and y values of the chart control, and upon the first execution of this code, it looks great. But when the page posts back and it "refreshes" data, the original points on the chart control are still there, as well as the new values.
Is there any way to "delete" all data in the chart control to ensure this doesn't happen?

C# - SQL - Returning Duplicates From Join?
Dec 17, 2010 My SQL query joins on multiple tables, and because of this it is displaying multiple results. I know about SELECT DISTINCT, but one of the fields ('Account.Name') is occasionally different, so it treats this record as a new row. Here is my SQL:

How To Remove Duplicates From A List In C#
May 3, 2010I want to remove duplicates from this list:
List<Dictionary<string, object>> val = new List<Dictionary<string, object>>();
It does not work if I apply Distinct() in this way:
List<Dictionary<string, object>> result = val.Distinct().ToList<Dictionary<string, object>>()
Update: Problem is now solved. I used the MySQL union command to read table from the database.

Jan 1, 2010I have a table named dups. There are 4 columns in the table.
id, name, path, hash
I want to return only the name, path, hash of each row where the hash field is the same. Example there are 100 rows but only two qualify the return would be.

SQL Server :: How To Union Two Queries Without Duplicates
Aug 27, 2010I have a sql query that returns 4 columns CustName CustId CustZip CustPhone
I have a second sql query that returns the following 5 columns
CustName CustId CustZip CustEmail CustAddress
Both queries, query different data tables in the database, but return columns that are common to
both.
How do I union the two queries(Assuming a union is needed)
Which will result in no duplicates and an end result being the following output:
CustName CustId CustZip CustPhone CustEmail CustAddress
As you can see we want to not have duplicate values on output. So something like the following
is not acceptable:

SQL Server :: Insert Date And No Duplicates
Oct 8, 2010I am importing images names from a file into a database by using the code below. When I import the image names, I aslo want to add a date of "June 12, 2009" in the DATE column. Finally, I do not want to import any duplicates. Is there something I can change in this code to make that happen?
declare @cmd varchar(1000)
set @cmd = 'dir "D:imagesREVIVE" /b'
if (object_id('ImageTable..tblimages') is not null)
begin
insert into tblimages (imgname)
execute xp_cmdshell @cmd
delete e
from tblimages e
where ISNULL(e.imgname, '') = ''
select *
from tblimages
end
else
create table tblimages ([id] int identity(1,1), imgname varchar(1000))
insert into tblimages (imgname)
execute xp_cmdshell @cmd
delete e
from tblimages e
where ISNULL(e.imgname, '') = ''
select *

.net - CssClass Duplicates On An UpdatePanel Update?
Apr 20, 2010I've got a simple user control in my ASP.NET Webforms project which inherits from the LinkButton. It's got a property to change the size, which just adds some predefined CSS classes to the control.
Protected Overrides Sub CreateChildControls()
Dim SizeClass As String = String.Empty
If Size = SizeEnum.Large Then
SizeClass = "large"
[Code]....
So when it renders the class property is something like class="button small".
When this control is placed inside an update panel along with some other things, when the update panel updates the class property for every one of these controls becomes class=" button small button small button small button small button small button small button small button small button small button small button small button small button small"
Web Forms :: Remove Duplicates From List Method?
Nov 16, 2010I have a Method that returns 4 records like this.
Name: Test1
Year: 2010
Value: $1000
Name: Test2
Year: 2010
Value: $1000
Name: Test3
Year: 2011
Value: $2000
Name: Test4
Year: 2011
Value: $1000
I need a way to get the unique years just ( 2010, 2011) rather than all 4 years, rest of the data could be duplicates.
Here is the method:
public List<TestCosts> GetTestvalues(string testid)
{
List<TestCosts> testlist = Testscores.List(testid);
return testlist;
}
Most of the examples of removing duplicates I saw have a list of one item only but in my case I have 3 items per record and I need to loop through each record, find the duplicate years, remove them and then return the distinct list of years along with the other data.
Web Forms :: How To Avoid Data Class Duplicates
Jan 7, 2010I have several LINQ-auto-created data classes which are created using dragging and dropping database tables into the Visual Studio LINQ design pane. Also, in my project I have to manually create WCF data-contract classes. Each WCF contract class is for one LINQ-auto-created data classes; one to one. Is there some better way to reduce the efforts to this problem? e.g. inheritance or something else to create WCF datacontract class from existing LINQ-data class.

Building An Import Process That Checks For Duplicates?
Dec 1, 2010Using ASP.NET, I'm building an admin tool that requires a function to import a list of email addresses. Upon uploading the file, I want to check for existing records for any of the email addresses supplied. For non-existing email addresses, I would create them using my DAO.
Basically I want to:
Receive list of emails
Retrieve data for existing emails
Create data for new emails in db
Return full data for all emails in list.
Since I want to know which of the emails exist up front, my first thought was to query the table for all records WHERE Email IN ('Email001FromFile', 'Email002FromFile', 'etc...') but the list could potentially contain thousands of email addresses, and I'm not certain supplying that many email addresses to the IN operator would be a good idea.
I also thought about looping through the list and checking for a record for each email, but that would potentially generate far too many queries.
My next thought was to generate a temp table to hold the list and modify the IN clause to use the temp table, rather than an explicit list of items, but that would require I execute SQL or a stored procedure directly, which I'm not inclined to do since I'm using NHibernate to access my DB.
Though I am using ASP.NET (C#) and NHibernate

If TextBox2.Text.Contains(DropDownList1.SelectedItem.Text) Then

m.Text = "duplicate !"

DataSource Controls :: Can Pull A Top Record And Avoid Duplicates
Feb 3, 2010I have location #s, date, time, the sales amount, and tax in a excel file. The system pulls sales numbers throughout the day from each store location and places the total sales and tax numbers along with the polling date into a file.
So the most current date/time has the most upto date sales numbers at the time for that location number, but it also lists the older entries so mgmt can see how sales went during the day, and this is where my issue is, I don't need to see the old numbers from this generated file (atleast at this part of the program).
What I would like to do is write a query that only selects the most recent sales numbers for each location. I will output this to a table in ASP.NET. The query I tried using the TOP 1 clause only gave me the very first row listed below.
