Web Forms :: How To Unique Hyperlink That Will Add The Data To A Database

Sep 1, 2010

I have a webform that writes respondent info to a sql data base. I want to send a email campaign and use a unique identifier so that if

1. joe clicks on his link http://www.test1.aspx?209

2. tim clicks on his link http://www.test1.aspx?603

that when they click the form submit the data gets written into the correct row where 209 and 603 are their respondent numbers already in the data base. This is my first attempt using c# and I couldn't find anything in my books about it.

Check Textbox Value Against Records In Database To Ensure Unique Value?

Jul 30, 2010

When a user enters a value I want to check against the other values in the database before allowing the record to be inserted.

It is a nvarchar type column.

Is it best to use a unique constraint (if so, how) or what would be the way to programatically check to make sure this name does not exist. It is not a username, just a name value that will be used in routing.

Efficiently Finding Unique Values In A Database Table?

Feb 11, 2010

I've got a database table with a very large amount of rows. This table represents messages that are logged by a system. Each message has a message type and this is stored it it's own field in the table. I'm writing a website for querying this message log. If I want to search by message type then ideally I would want to have a drop down box listing the message types that have come up in the database. Message types may change over time so I can't hard code the types into the drop down. I'll have to do some sort of lookup. Iterating over the entire table contents to find unique message values is obviously very stupid however being stupid in the database field I'm here asking for a better way. Perhaps a separate lookup table which the database occasionally updates listing just the unique message types that I can populate my drop down from would be a better idea.

The platform I'm using is ASP.NET MVC and SQL Server 2005

Jul 5, 2010

I am generating a unique Ref number using this sql statement: SELECT REPLACE(STR(CAST(CAST(NEWID() AS binary(5)) AS bigint),12),0,0) as REF Subsequently, I need to insert this REF into sql database table in stored procedure. Here is what I did in my stored procedure:

USE [iBankRecords]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROC [dbo].[stp_addPayee]
(
@CUSTID char(10),
@PAYEEACCNUM nvarchar(20),
@PAYEEACCTYPE char(10) ,
@PAYEENAME char(20),
@PAYERINITIAL char(20),
)
AS
DECLARE
@ReturnValue int
INSERT INTO PAYEE (CUSTID, PAYEEACCNUM,PAYEEACCTYPE,PAYEENAME,PAYERINITIAL, REF)
VALUES (@CUSTID,@PAYEEACCNUM,@PAYEEACCTYPE,@PAYEENAME,@PAYERINITIAL, REF)
IF @@ERROR<>0
BEGIN
PRINT 'ERROR'
SET @ReturnValue=1
RETURN @RETURNVALUE
END
ELSE
BEGIN
SET @ReturnValue=0
RETURN @RETURNVALUE
END

May I know how do I have generating a unique ref num and inserting the REF into the above statement?

SQL Server :: Using A Database Field As A Hyperlink Query?

Sep 3, 2010

I have three tables in my sql database

contacts

survey answers

respondent_initial

Contacts holds all customer data with custid.

survey answers has assigned everyone how took the survey a number in a field called
respondent_no.

respondent_initial holds input from a webform where I populated it with the custid from contacts and respondent_no from survey answers before the webform input is inserted.I want to send an email to them that had there respondent_no in a hyperlink to the webform so that when they entered their data into the webform it would use the repondent_no to determine where to insert the form data.

Example joe clicks http://www.myplace.com/order.aspx?23

Mike clicks http://www.myplace.com/order.aspx?125

it would look up respondent_no (23) from the respondent_initial table and insert the data in that row in the database for joe's webform entry and it would look up respondent_no (125) from the respondent_initial table and insert the data in that row in the database for mike's webform entry. my code behind looks like this

// Create command
comm = new SqlCommand("INSERT INTO respondent_inital (Practice_Name, Address1, Address2, City, State, Zipcode, Phone, Email, Contact, Dealer, item_9223, item_9129, item_42795, item_30695, item_42834) VALUES (@Practice_Name, @Address1, @Address2, [code]....

Forms Data Controls :: Convert Gridview Data Cells From Text To Hyperlink?

Feb 14, 2010

1. First i am populating a datatable with two columns of type text. The second column is a hyperlink (but i am not specifying that datacolumn type as hyperlink).

2. After populating the rows, i am adding the datatable to dataset.

3. then binding this dataset to the gridview (the gridview's AutoGenerateColumns=true).

Question:

Obviously, the hyperlink column is represented as text in the gridview (non-clickable hyperlink).

here i am trying to convert this hyperlink column (data rows), from text to a hyperlink, so that the user can click directly and navigate to that url.

FYI, I cannot change this method of binding, and just want to convert this text hyperlink to a real hyperlink.
