Hi,
to get SelectedRow you have to Create an event of TestGridView_SelectedIndexChanged.
Here in this event you can get selected rowindex as well as any cell's value from selected row.

Thanks,

It's usually a better idea to send your search criteria to your data source and let it do the filtering for you, and your code just handles binding to the data returned

1.Fill a DataTable and Bind ur grid at first time with this DataTable

2. Set a DefaultView for the above DataTable.

3. And filter this DefaultView with with ur Search Text Box Value...

4. At last Bind ur grid with above DeafaultView in a Search Button Click or any other event...

This code is properly working;

FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, userID.ToString(),
DateTime.Now, DateTime.Now.AddMinutes(30), false, userRole.ToString(), FormsAuthentication.FormsCookiePath);

string encTicket = FormsAuthentication.Encrypt(ticket);

HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);

cookie.Expires = DateTime.Now.AddYears(1);

Response.Cookies.Add(cookie);

Response.Redirect(FormsAuthentication.GetRedirectUrl(userID.ToString(), false));

*****But if I use Try-Catch pattern, catch block is running;

try
{
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, userID.ToString(), DateTime.Now, DateTime.Now.AddMinutes(30), false, userRole.ToString(), FormsAuthentication.FormsCookiePath);

string encTicket = FormsAuthentication.Encrypt(ticket);

HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);

cookie.Expires = DateTime.Now.AddYears(1);

Response.Cookies.Add(cookie);

Response.Redirect(FormsAuthentication.GetRedirectUrl(userID.ToString(), false));
}
catch (Exception ex)
{
Response.Redirect("ErrorPage.aspx");
}

Exception Error Message is;
ex = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}

Why I get this message? How can I correct it?

Accually this code solve my problem;

try
{
//My Code
}
catch (System.Threading.ThreadAbortException ex)
{
//ignore error.
}
catch (Exception ex)
{
Response.Redirect("ErrorPage.aspx");
}

But I think this is not a good solution.
Why do I get this message? How can I correct it?

From the MSDN documentation for HttpResponse.Redirect:

'Redirect calls End which raises a ThreadAbortException exception upon completion.'

It is part of the implementation of the Redirect method that a ThreadAbortException is raised. You can catch that particular exception and ignore it.

Hello I have a string variable declared in a Webform

Is there a way in which I can modify the value of that variable with javascript?

can I use something like getElementById, or something that can allow me to get that variable?

thanks

It's a server side variable (declared in the C# code),the answer is no. You can use for instance a hidden field , and in a postback get that value.

ASP.NET can't do anything on this because it works on the server. You may do this using JS. AFAIK, no built-in controls available for such a requirement.
