To make you understand take a small example. Suppose we want to make a simple signup form (in which we will not check similar username or duplicate user name; I hope you can easily do it). So make a table with two columns 'UserID' and 'Password'. Take three text box one for username and other two to match and insert password (You can use java script to match password; I am not including it here). A button which will insert data in data base after clicking it. Write this code after closing form tag and just above closing of body tag. <script type="text/javascript">         $(document).ready(function () {             $("#Button1").click(function () {                 $.ajax({                     type: 'post',   ...

But doing this with help of session is not considered good so here we will use other technique as well.. Suppose you have Page 'a.aspx' and other page 'b.aspx' you want to pass value from one to another then on first page write this code but before this suppose you have a link button on click of this associated value will pass to 'b.aspx'. code on click event of link button in 'a.aspx' Response.Redirect(" b.aspx?value= " + here you should write variable of reference variable); Response.Redirect(" b.aspx "); on the page 'b.aspx' of page load event write following c...

Yesterday I was trying to fetch data from SQL server with the help of SqlDataReader but I got an error message " open DataReader associated with this Command which must be closed first " I search a lot on internet and got a solution regarding this problem. It was advised by someone that when you are reading data from server and trying to insert, delete or update action with the same connection then you will face such error which will told you to close the reader first. To get the solution for this problem you should do two things. 1. Use SqlDataAdapter and Fill command when you do not want to make an other connection for insertion and other things other than read. 2. use separate sql connection for insert, delete or update action. i.e when you have a SQL Connection 'Con' for reader. Then you should use other SQL Connection for other action. Someone also advised to add MultipleActiveResultSets=Truein connection string. Hope this will help you a lot...

To understand this suppose you want to store various RSS Feeds news for further analysis then you will automatically refresh your page in certain time interval but in such situation your database will capture various duplicate entry also. To avoid such thing happen with you you will have to manage it will proper algorithm. Okay look at this technique and i hope this will help you a lot. 1. Take Two Table named as "FirstTable" and "SecondTable". Second Table will be your main table which stores actual data without duplicate entry. First Table will store updates only. 2. With the help of some logic we first take our updates first to "FirstTable" and then we will check weather "SecondTable" has same rows or columns. 3. If it has same rows and columns then delete...
