    how to send sms from asp.net application to mobile

    • Chandra Dev December 25, 2010 / 6:16 pm

      Sorry for late reply. For sending sms from asp.net application to mobile, we have to take help of “Sms Gateway” which will be provided by some other company. That will be payable. There are so many service provider for Bulk sms. They will give the “Developer Api Code”. We have to do little bit modification on that code then we can implement in our application.

      For testing this functionality, you can refer this site
      and you can also read this thread in asp.net forum for more detail.

  17. Chandra Dev October 6, 2011 / 11:26 am

    Hi, Chakri
    I suggest you to learn any new technology step by step. If you will start from middle then you will face some problem. So you start to learn from basic then go in dept. I also do same things. I have written so many artical on WCF category. You start to learn from basic.
    If you will get any problem then let me know.


  18. yemireddykri October 20, 2011 / 6:28 am


    How are you?,How can i get image into gridview which is stored as a binary formate in the database,I got some extent using handler but image was not coming,Please give me idea,Moreover i want only single record using only selected person name,based on the person name only i will get the data.


  19. Chandra Dev October 22, 2011 / 11:36 am

    Hi Chakri,
    Sorry for late reply, I was some more busy in last week.

    You donot follow this approach to store image in database. If you are going to display more image at one time from database then it will very slow.

    Before 1 yr i had written one artical, you do like this

    If you will get any problem then feel free to ask. I will send reply quickly.

  20. suresh March 2, 2012 / 10:46 am

    Hello Sir

    i am create s website sms gateway
    how can we implement group sms in our applcation and how can send sms from our website to mobile no

  21. Chandra Dev March 3, 2012 / 2:13 am

    Hi Suresh,

    I hope that you are aware of sending sms to single person. For sending sms to multiple Users fetch the all mobile No from database using sql query or LINQ. Then store it in datatable or list and keep there some loop like for or foreach in datatable or list. Then sms will go to multiple users.

    If you have still problem then fell free to ask with me.

  22. chakri March 21, 2012 / 7:38 am


    I have dought on when will i use polymorphism consept and when will i go for abstract or interface concept while project implementaion.


    • Chandra Dev March 23, 2012 / 12:27 pm

      Hi Chakri,

      I am preparing artical on this topic. I will show you with code.


  23. Megana April 26, 2012 / 4:41 am

    I Have doubt on MySQL query(i.e) ‘m using a query like
    Delete * from NoteAttach where N-Id=(select ID from Note where B-id=2);
    but the problem is B-id=2 has its N-Id values 1,2 . here only the id’s 1 are getting delete but not the 2. so what query can i use for this.

  24. Chandra Dev April 29, 2012 / 11:15 am


    If You have to delete multiple record at one time then you can write like
    Delete from NoteAttach where N-Id in (select ID from Note where B-id=2);

    I m sure, this will work in sqlserver. But in Mysql, i don’t have tested, Please test it and confirm me.

  25. Amey February 14, 2013 / 5:39 pm

    Hello can you tell me about database connectivity in C# .NET & ASP.NET & how to show data on particular page or form

    • Chandra Dev February 15, 2013 / 2:21 pm

      Could you tell me properly, do you want to get connection string or somethings else ?
      If you want to get connection string of database then you can take sqldatasource control and you can get from that control.

      if you have still confusion then let me know.

  26. Amey February 16, 2013 / 5:36 pm

    • Chandra Dev October 28, 2013 / 6:25 pm

      I m fine. For sending sms you have to consume api code which will be provided by service provider and that will be payable service. They used to give api code to integrate in website. But they used to charge some money.

    hello sir,
    after long time i required your help,i read your 3 tier application article which is too good but i have some problem in 3 tier architecture i have the requirement insert data through footer in gridview from two tables using stored procedure.First table is employee column name empcode,name,departmentid and designation and second table is department column name is departmentid and departmentname,where empcode is in the form of “emp001” which is primary key and department id is primary key in second table.And it also perform update,edit and delete option.In gridview it shows column empcode,name,desigantion,departmentid and department name.

    • Chandra Dev May 1, 2014 / 3:57 am

      Hi Rahul,

      This is straight forward. You create 2 tables i.e tblEmp and tblDept i.e in tblEmp you give EmpId as PK,
      EmpName,EmpDetails and DeptId as FK. In tblDept you can give DeptId as PK, DepName etc. where tblDept is master table.

      you save all the required information with DeptId in tblEmp. You can also delete that record with EmpId.

      if you are still getting the problem, please let me know where are you getting the problem?
