Getting data from a selected row in a gridview

Hi Vardhan,
I tried with Web Application instead of Windows App and used GridView. In the loop, where you are retrieving data in the lists, that part is fine. Its working fine too in my web app.
The problem is in only in the line:

   CheckBox chk = (CheckBox)row.FindControl("chkSelect");

error(website application) .....in gridview retrive  the rows cells...

please make correction  

 protected void btnSend_Click(object sender, EventArgs e)
    {
        List mobilenumbers = new List();
        List data = new List();
        if (gv.Rows.Count > 0)
        {
            for (int i = 0; i <= gv.Rows.Count - 1; i++)
            {
                GridViewRow row = gv.Rows[i];
                CheckBox chk = (CheckBox)row.FindControl("chkSelect");
                if (chk.Checked == true)
                {


                    mobilenumbers.Add((gv.Rows[i].Cells[5].Text));
                    data.Add((gv.Rows[i].Cells[2].Text) + (gv.Rows[i].Cells[4].Text)+(gv.Rows[i].Cells[6].Text));
                    //data.Add(row.Cells["NAME"].value.Tostring() + "\t");
                   
                   






                }


            }
            clssms obj = new clssms();
           
            for (int j = 0; j <= mobilenumbers.Count - 1; j++)
            {
                for (int k=0; k<=data.Count-1; k++)
               
                {
                   
                   string str = obj.SendSMS("****", "****", "91" + mobilenumbers[j] + "", data[j], "SMSCntry", "N", "N");
                    Response.Write(str);

I dont' know why I am not able to attach zipped project folder.... anyway in That project I made a class PersonalRecord like this:

    public class PersonalRecord
    {
        public bool IsChecked { get; set; }
        public int sno { get; set; }
        public string name { get; set; }
        public string fname { get; set; }
        public string add { get; set; }
        public string dob { get; set; }
        public string mobile { get; set; }
        public string email { get; set; }

        public PersonalRecord(int sn, string nm, string fn, string ad, string db, string mb, string eml)
        {
            sno = sn;
            name = nm;
            fname = fn;
            add = ad;
            dob = db;
            mobile = mb;
            email = eml;
        }
    }

and bind the grid in the following way:

        private void Form1_Load(object sender, EventArgs e)
        {
            List lstSession = new List
            {
            new PersonalRecord(1,"pavan","raju","hyd","1/02/1990","9898899999","svx@fg"),
             new PersonalRecord(2,"naveen","praveen","hyd","2/1/1989","987345666","jkl@iu"),
              new PersonalRecord(3,"mohan","shri","hyd","2/1/1979","98732266","mnk@iu"),
                new PersonalRecord(4,"kapil","dev","Del","2/1/1969","981125666","kpll@iu"),
            };

            dataGridView1.DataSource = lstSession;
            dataGridView1.ClearSelection();
        }
   

Hope it would help. If it solves ur problem, mark this thread as accepted.

Thanks,

Actually I made a small program for this and that sample project is attached. You may go thru this and let me know if you find any issue. In this you would see grid like this:



and get output like this:

I would try like this:

        private void btn_ShowSelecteddata_Click(object sender, EventArgs e)
        {
            List mobilenumbers = new List();
            List data = new List();

            foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                if (Convert.ToBoolean(row.Cells["IsChecked"].Value) == true)
                {
                    mobilenumbers.Add(row.Cells["mobile"].Value.ToString());

                    data.Add(row.Cells["name"].Value.ToString() + "\t" +
                        row.Cells["fname"].Value.ToString() + "\t" +
                        row.Cells["add"].Value.ToString() + "\t" +
                        row.Cells["dob"].Value.ToString() + "\t");
                }
            }

            StringBuilder sb = new StringBuilder();

            for (int i = 0; i < mobilenumbers.Count; i++)
            {
                sb.Append("Send SMS to " + mobilenumbers[i] + " with message \t" + data[i] +"\n\n");
            }

            MessageBox.Show(sb.ToString());
        }

Please check and make corrections


List mobilenumbers = new List();
        List data = new List();
        if (gv.Rows.Count > 0)
        {
            for (int i = 0; i <= gv.Rows.Count - 1; i++)
            {
                GridViewRow row = gv.Rows[i];
                CheckBox chk = (CheckBox)row.FindControl("chkSelect");
                if (chk.Checked == true)
                {
                            data.Add((gv.Rows[i].Cells[1].ToString()+gv.Rows[i].Cells[2].ToString()+gv.Rows[i].Cells[3].ToString()+gv.Rows[i].Cells[4].ToString());
                   
                    mobilenumbers.Add ((gv.Rows[i].Cells[5].Text));
                   
                   


                }


            }
            clssms obj = new clssms();
            for (int j = 0; j <= mobilenumbers.Count - 1; j++)
            {
                string str = obj.SendSMS("name", "password", "91"+mobilenumbers[j]+"", data.Text, "SMSCntry", "N", "N");

Set the DataGridView select property to Single Row Select.
 then try this code,

DataGridViewRow row = dataGrid1.SelectedRows[0];

string data = row["name"].Value.ToString()
                        + row["fname"].Value.ToString()
                        + row["add"].Value.ToString()
                        + row["dob"].Value.ToString();

string mobileNum = row["name"].Value..ToString();
