Hi,
here u are creating new Datatable object. And then trying to delete from that. So how it will work ? 
You must have data in datatable.

I can't seem to get this to work. I just doesn't do anything at all. I've been working on it for about a week and I think I'm doing something fundamentally wrong here. I know I'm executing my Calendar1_DayRender event because when I just make it draw peachpuff for a background color it does it. However I can't get the access to my document to go right. I'm not really sure if it's accessing my document correctly, and the debugger isn't communicating to me. Is there a better way to do this? (such as putting the data-access in a different method and calling it from the event?)
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
XDocument eventsXML = XDocument.Load(Server.MapPath("Events.xml"));
var events = from theevent in eventsXML.Descendants("event")
where theevent.Element("event") != null
select new
{
Organization = theevent.Element("organization").Value,
Creator = theevent.Element("creator").Value,
Name = theevent.Element("name").Value,
Description = theevent.Element("description").Value,
Location = theevent.Element("location").Value,
EventDate = DateTime.Parse(theevent.Element("Date").Element("Day").Value)
};
var thismonth = from item in events
where item.EventDate.Month == DateTime.Now.Month
select item;
foreach (var item in thismonth)
{
if (item.EventDate.Date == e.Day.Date)
e.Cell.BackColor = System.Drawing.Color.PaleVioletRed;
}
}

"1.0" encoding="utf-8" ?>

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.

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

This is a good Idea for searching I rectnly complete it into my project
the steps are follows....
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...
Hope this we'll help u...

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?
Thanks...

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?
Best Regards...

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.
