Regarding Linq to SQL with .SQLEXPRESS and VS2010 on Windows 7, I am trying to add a list of entries to an empty table that I have confirmed programmatically does not have duplicate keys. Some info about the situation:Note: The key strings have Unicode characters (English and Chinese mixed).

I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.
I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:
I used the following query to load in duplicate records:
SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))
ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006
What is the query to delete single duplicate record instead of deleting all duplicate records?
I have a very simple question. How do I simply duplicate a page that has already been created?
View 1 RepliesWhen we have anything that requires user input (Eg adding a product to a database) the Edit screen looks the same as the add screen. When using MVC .Net how do you handle this? Do you return the same view? Just adjust the model to reflect the change?
View 4 RepliesI Have an ASP:Table that has a row with cells in I need to be able to add a row to this by clicking the Add button at the end which duplicates the existing row. My Table code

int rowCtr;
// Total number of cells per row (columns).
int cellCtr;

rowCnt = int.Parse(TextBox1.Text);
cellCnt = int.Parse(TextBox2.Text);
for (rowCtr = 1; rowCtr <= rowCnt; rowCtr++)
{
// Create new row and add it to the table.
TableRow tRow = new TableRow();
Table1.Rows.Add(tRow);
for (cellCtr = 1; cellCtr <= cellCnt; cellCtr++)
{
// Create a new cell and add it to the row.
TableCell tCell = new TableCell();
tCell.Text = "Row " + rowCtr + ", Cell " + cellCtr;
tRow.Cells.Add(tCell);
}
}
}

i'm using linq to sql and c#
I'm designing a web page with two dropdownlists, one for the Make of a car, the other for the Model, both bound to a database with separate SQLDataSources, and using a distinct statement. I add "All" at the top of both by setting appendDataBoundItems = true and adding items named all. Then when I fill the Make with a querystring all the model items get added twice (but only the databound items).Here's my code:
<asp:DropDownList ID="DropDownMake" runat="server"
DataSourceID="SqlMakes" DataTextField="Make" DataValueField="Make"
AppendDataBoundItems="True" EnableViewState="False" AutoPostBack="True">
<asp:ListItem Selected="True" Value="All">All</asp:ListItem>
</asp:DropDownList>
<asp:DropDownList ID="DropDownModel" runat="server"
AppendDataBoundItems="True" AutoPostBack="True" DataSourceID="SqlModels"
DataTextField="Model" DataValueField="Model" EnableViewState="False">
<asp:ListItem>All</asp:ListItem>
</asp:DropDownList>
<asp:SqlDataSource ID="SqlMakes" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT DISTINCT [Make] FROM [Parts]">
</asp:SqlDataSource>
<asp:SqlDataSource ID="SqlModels" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT DISTINCT [Model] FROM [Parts] WHERE ([Make] = @Make)">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownMake" Name="Make"
PropertyName="SelectedValue" />
</SelectParameters>
</asp:SqlDataSource>
'And in the VB file:
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
DropDownMake.SelectedValue = Request.QueryString("Make")
DropDownModel.SelectedValue = Request.QueryString("Model")
End Sub
If I remove the line "DropDownMake.SelectedValue = Request.QueryString("Make")" it doesnt produce duplicates anymore. What is going on?? I swear I've spent more time developing entire iphone app.
i have a dropdownlist (asp.net control) and a listbox control and a Add button when the user select the item from dropdownlist and click on add button to add to the listbox.
how can i prevent the user from adding duplciate items and alert saying its already in the listbox?
UPDATE:
in my particular scenario, i have a dropdwonlist and adding the item to listbox both are asp.net controls and i am adding the items from code-behind and your solution is pure on client side, is there a way i can read the listbox and compare and alert the message?
Simple one here... is there a clean way of preventing a user from double-clicking a button in a web form and thus causing duplicate events to fire?
If I had a comment form for example and the user types in "this is my comment" and clicks submit, the comment is shown below... however if they double-click, triple-click or just go nuts on the keyboard they can cause multiple versions to be posted.
Client-side I could quite easily disable the button onclick - but I prefer server-side solutions to things like this

I am calling a web service in my aspx page. the web service (written in java) is acting as a middleware between my system and another system (Siebel) to which I send services and get response for these services. some requests are synchronous. Sometimes when invoking a method the response takes a long time to respond, so a time out exception is thrown.
The problem is that the web service is receiving the same request many times despite I am calling it only once.In my log file and database entries it is clear that the request is called only once. but in the middleware and Siebel side they are receving four or five requests for the same request sent by me.
Is this a bug in asp.net. is it possible that the server where my application is deployed is sending the request many times when not getting the response.Note: iam using Visual studion 2005. the application is deployed to windows server 2003.Iam not discussing the problem of time out. iam asking about the duplicate issue.
I have a program that parser html and collecting urls. The problem is when checking for duplicates before I add them to an arraylist is that I cannot distinguish between types of the following format:

http://forums.asp.net/AddPost.aspx?ForumID=15/helloworld.asp
http://forums.asp.net/AddPost.aspx?ForumID=15/helloworld.asp/byeworld.html
Now if I captured the first url, how can I avoid collecting the next few since they are not technically duplicates.
I have an ASP:Table that has one row in by default. I would like to give the user the ability to, by clicking a button, add the same row again to enable more data entry. The end result being that I can commit the data in the rows to a SQL database.
