I have 3 textboxes and one submit button outside gridview. This textboxes submit value to gridview.
I want to be able to check and stop duplicate value in gridview.
suppose I am having sample table like below.
I need to remove duplicate orderid's and i need all column names also while doing query.
note that rows are not in the order. Order will be like this only.
I am able to get the records which are duplicated but not able to delete further.
In this case how to delete?
My consideration is that only distinct orderid's should be there in the table. Not bothering about the which orderid row is being deleted.
name orderid destination
a 1 aaa
d 2 ddd
b 1 bbb
f 3 fff
e 2 eee
g 4 ggg
h 3 hhh
c 1 ccc

View 5 RepliesI'm new to ASP.NET MVC and I'm trying to implement an address manager.I'm using Linq2Entity Framework. I've got a table with contacts and one with phone numbers. These two tables are linked by a contact_has_phone_number table. The Entity Framework enables me to get all phone numbers that are assigned to one contact. This is done by calling contact.PhoneNumbers which returns a collection of phone numbers.
View 1 RepliesHow do you avoid duplicate bound items in this scenario: There's a databound control on a page (a DropDownList in this case, though I don't think it matters). It has AppendDataBoundItems set to "true". Somewhere in the code, a DataSource is set and DataBind is called. So this control is bound explicitly. You have a bunch of other things to bind on the page, so you call Page.DataBind.
Your databound control now has duplicate items in it. It was (1) bound explicitly, then (2) Page.DataBind bound it again. Since AppendDataBoundItems was true, the second bind appends to the first, and you end up with double the items. A couple limitations: The explicit call to DataBind on the control is done through some centralized code, and would be painful to change. i really need to bind the rest of the page in aggregate (via Page.Databind()) because there's too many other databound elements to do it individually without writing a ton of individual calls.
I need a method like... Page.DataBindExceptIfTheyHaveAlreadyBeenBoundDuh()
I have a receipt page for my clients that will display their info and they will get notify by an email message. Here is the problem: when user hit refresh button from a brownser, it will send duplicate email message to the user.
This is what i have:
protected
void Page_Load(object sender,
EventArgs e)
{ if(!IsPostBack)
SendEmail()
}
protected void SendEmail()
{ //here is my function for email
}
I need to force every request to https://www.mysite.com (always with https and www)
The site is hosted in GoDaddy and I need to do it via IIS7 URL Rewrite Module.
I've been able to do the HTTPS redirect with the following code:
<system.webServer>
<rewrite>
<rules>
<rule name="Canonical Host Name" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^mysite.com$" />
</conditions>
<action type="Redirect" url="https://www.mysite.com/{R:1}" redirectType="Permanent" />
</rule>
</rules>
</rewrite>
</system.webServer>
Test cases
http://mysite.com -> https://www.mysite.com OK
http://www.mysite.com -> https://www.mysite.com NOT WORKING
I guess the condition is not being satisfied when I enter www.mysite.com in the browser, so there's no redirect and the page serves as HTTP instead of HTTPS.
I think I just need to modify the condition pattern, but I have almost nothing regex knowledge and I need this asap.
After postback if user presses F5 or refresh duplicate values are inserted.

I have 2 listboxes, when i add a item retrieved from database to Listbox1, i need to select the item and bring it to listbox2. But i do not want to have same records added again. In my case, i cannot use the codes below
[Code]....
because the text displayed on listbox1 and after transferring to listbox2 are different. So i come out with a logic which is "if listbox2 does not contain the item value in listbox1 then populate listbox2". So i tried the codes below, but it is not working as there are errors

View 1 RepliesWell the dropdownlist has an existing items. I just want the selected gridview record to be displayed in the dropdownlist. The dropdownlist has several DataTextField in string and consist of DataValueField in numeric. The gridview passes a string text to the box which has an equal or same item inside the dropdownlist. Whenever i passed a record from a gridview to be viewed in the dropdownlist it just duplicates the same item. Q: How can i simply pass a text inside the dropdown and just simply display it without adding on the list.
sample item on the dropdown:
--Select--
Account
Savings
after selecting on the gridview and display inside the dropdown:
Account
Account
Savings
(you see the '--Select--' was erase and replace with the selected record)

View 1 RepliesI have a master table relationship, i.e. depending on what is selected in the dropdown list the grid show the relevant data.In the database there are several identical entries for the Position field, for instance there are four marketing managers that have different name. How can i group the identical Position name in the dropdown and when selected the grid should display all marketing managers. Here is the code:
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="sqlDdl"
DataTextField="ID" DataValueField="Postion">
</asp:DropDownList>
<asp:GridView ID="grid" runat="server" AutoGenerateColumns="False"
DataKeyNames="ID" DataSourceID="sqlCon" EnableModelValidation="True">
[Code] ....
The user will enter values in the textbox of the gridview in item template. A button outside the grid, when it is pressed we have to highlight the duplicate values.
Is there is any way to use validation control.

I have a gridview containing serial-numbers.
I would like to format the background each data-row that contains a duplicate serial-number value.
I'm planning to do this using a DataBound event handler.
So, in English:
Set background colour of THIS_ROW to red where the Serial_Number of THIS_ROW is the same as the Serial_Number of ANY_OTHER_ROW.
All rows with duplicate serial-numbers would be red.
I'm not sure how to write the code for this event.
The gridview is bound to a SQL datasource. Getting the dupes in SQL is easy:
SELECT Serial
FROM Table
GROUP BY Serial
HAVING (COUNT(Serial) > 1)
I want to generate 30,000 cards and each card must be duplicate check with database. In my card, there are 2 things. Serial No and CardID. If any card already exists then I generate another card id but with the same serial no.
So how faster way I can generate 30,000 card with duplicate check? Which one I have made application, it takes about 25 minutes to insert.
