Hi,
for that you have to use viewstate and have to add arraylist in viewstate, and have to append arraylist on every selecion of row of gridview.

getvalue is value which you are fetching from gridview's selected row.
As you want to add value from grdview.selected row's cell's value.

in the username. field "Ramesh" is there ..
i want to calculate that how many times "ramesh" is there in the username field..using sql

This must be in SQL Forum, this has nothing to do with ASP.NET.
Select count(*) from table where username = 'ramesh'

Is the code to add controls dynamically is written in Page_Init or Page_Load? If you have written the code in the Page_load then it will not behave as you expect it to...and the controls won't participate in the viewState too.

The session won't be expiring. It's your programming mistake. Can we have a look into your code ?

Sure, this is Login Page code.....
private void BtnGo_Click(object sender, System.EventArgs e)
{
Label1.Visible=false;
bool persistcookie=true;
if(ValidateUser(TextBox1.Text,TextBox2.Text))
{
//string globalstrConn="Provider=SQLOLEDB;Data Source=localhost;Initial Catalog=iMedia;Integrated Security=SSPI;";
Session["UserName"]=TextBox1.Text;
//This will store the username of the user in this session variable
// We can retrieve this username on different pages by using following code.
// string str=Convert.ToString(Session["UserName"]);
FormsAuthenticationTicket tkt;
string cookiestr;
HttpCookie ck;
tkt=new FormsAuthenticationTicket(1,TextBox1.Text,System.DateTime.Now,System.DateTime.Now.AddMinutes(Convert.ToInt32(ConfigurationSettings.AppSettings["timeout"])),persistcookie,"Your Custom Date");
cookiestr=FormsAuthentication.Encrypt(tkt);
ck=new HttpCookie(FormsAuthentication.FormsCookieName,cookiestr);
if(persistcookie)
ck.Expires =tkt.Expiration;
ck.Path =FormsAuthentication.FormsCookiePath;
Response.Cookies.Add(ck);
string strredirect;
strredirect=Request["ReturnUrl"];
if(strredirect==null)
strredirect="login.aspx";
Response.Redirect(ConfigurationSettings.AppSettings["defaultpage"],true);
}
else
{
Label1.Text="Invalid Credentials!";
Label1.Visible=true;
// Response.Redirect("login.aspx",true);
}
}

How to make a dropdownlist to be selected based on HTML anchor tag selection
|
|
|
|
|
You can access any control in code behind by adding runat='server'
Not sure how you want to select a dropdown based on a link tho. You probably want to do whatever you're doing in script, not code behind.
