You don't mean a mail server. You mean you want to write a webmail client. Of course, that's actually pretty easy. You do need a mail server through which you can send the mail, and you need to be able to create mail accounts on that server, but those are not ASP.NET tasks.

I have two dropdownlist.one for country and second is for state.when I select country its state will be bind in second dropdownlist.but i am getting following error here.I do not want to set enableEventValidation=false in page directory.
can any one tell me why this error occurred?
<br />
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Look around you. Everyone has an urgent question.
You're going to do this with javascript, and if you want to do a save, you'll have to use AJAX, I reckon. There are controls you can buy that do this, I'd say they are worth the money.

Hi,
Any one please give some solution.
I am using a web service which return me the premium value in string format as 2345,564(German Currency Format). Now I have to divide it by 12/6/4 to calculate the premium on yearly/half yearly/monthly basis.
After dividing the resutant shoul be converted into the relevent currncey format i.e German or English.
2345,564 is 2345,564 in English culture.

What does this have to do with ASP.NET ?
Sounds trivial, in any case. Why are you stuck, on what bit ?

Hi all!
How can i reset the query string without redirecting but using postback?
From = ".../Main.aspx?Results=1"
To = ".../Main.aspx"
So when i click a button it does the above without redirecting it;
"response.redirect("Main.aspx")
Thanks in advance!
Regards,
Jensen

Reseting querystring on postback is not possible. Why you want to do this

Hi Guys/Girls,
Have been beating my head against the wall over this one for a while, and have come to the conclusion that I have probably just overlooked something simple. I am happy to look at alternative methods to open the popup page, but would prefer to keep the existing method for the download of the file.
Here's the situation:
In the on-click event of a button I do some processing, then want to do two things (in no particular order)
1. Pop up a window that opens a page that displays a crystal report as a PDF (this page exists and works fine in its own right)
2. Download a file. (this function also works fine in its own right)
Here's the rub:
Currently, I use response.write to trigger the page popup like this:
Response.Write("<script language=javascript>window.open('pagename.aspx?ReportID=49&Param1=" & intParam1 & "','new_Win');</script>")
(I can't attach it to the link attributes as the param1 needs to be generated by the processing in the existing on click code.)
Then, I use functions that end up calling the following code to download the file:
<preprocessing happens here>
With Response
.AddHeader("Content-disposition", "attachment;filename=" & strFriendlyName)
.ContentType = "application/octet-stream"
.BinaryWrite(btFile)
.End()
End With
Naturally, with the code as it stands the system throws a hissy-fit as you can't use two responses for the one page (by design). Surely there is some way for me to open the crystal report/pdf viewing page in code without using the response.write or response.redirect, that will allow for the processing of the rest of the code (and hence the downloading of the file)???
As I said, I have probably missed something incredibly simple, and you ASP.NET gurus are going to go "silly bugger, why don't you just open the popup by using XYZ"... I am prepared to wear that!
Thanks in advance...

You can't.

That's correct.

No. If you send the file to be downloaded in the response, there is no way of sending anything else what so ever in the response. Nothing. Nada. Zilch. Zip.
You have to make two separate requests to the server.

That's what I was afraid of...
Is there some way to trigger the popup form (other than using response.write) so that I can still use the response for the file download, or am I just going to have to redesign the process?
Thanks for taking the time to answer...

You have to send two requests from the browser. You can either send both requests from the same page, or let the popup page send the request for the download.
It can't be done the other way, though. The request for the download is a dead end, and can only return the data for the download, it can't cause another request.

No worries... Thanks again for your help.
I have resolved the issue by processing and producing the pdf on the first click, saving the ID to session state and then using a second click event to handle the creation of the file.

I am trying to pass some parameters from one page to another. I have a project where if someone is a manager they can approve/deny certain requests. However, I am trying to display a message box alerting a user they cannot do certain functions. I created a simple example for her. I can click on a link on the first page that passes parameters in the URL. I grab the parameters. The problem is, it never displays the popup when I have response.redirect after it.
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Response.Write(Request.QueryString["OrderBy"].ToString());
Response.Write("<br /><br />" + Request.QueryString["Page"].ToString());
Response.Write("<script language='javascript'>window.alert("+ '"' + Request.QueryString["OrderBy"].ToString() + '"' +");</script>");
Response.Redirect("Default.aspx");
}
}

Well, of course. Response.Redirect happens on the server, the page with the script is never sent to the client. You need to write this script into the default.aspx page, or pre populate the page so that on the client side, when the action is performed, the javascript runs prior to the postback.

Hello, i have a real time data problem,
Let me explain,
Im building a web site, in order to user acces to check the status of an application, ive already have the process to keep update the data, ive an arraylist, where I put the modified data , the a timer updates the data, so, I have a data table … a static data table, so what I do , I just modify the data, with the editrow( ) function, then I pass the object to a dataview so the paga can be repainted, so everything goes well to that point.
Why I have static table, ok, first cause my fuction is static.. so.. then cause I need that the data be the same for other users, so when I run the page on a server all the users see the same data on the table.
Ok the problem comes when each user initializes the page, cause, the initialize process “try” does the process of adding colums to the data table , colums that already exist, so a error message pop ups, telling me that it cant be created again, ok so… what im doing,
First I cant use a non static data table, cause each time a user enters the page, it wont have any data, … so, im trying to have a non static data table, then when I get a modification on the data I use this, (Im passing the structure from the non static data table to the static)
DataTable static StaticDatatable =new DataTable()
DataTable static NonStaticDatatable =new DataTable()
if (loadatfirst == 0)
{
DtMotor.Columns.Add(new DataColumn("Numero", typeof(string)));
DtMotor.Columns.Add(new DataColumn("Nombre", typeof(string)));
DtMotor.Columns.Add(new DataColumn("Estado", typeof(string)));
DtMotor.Columns.Add(new DataColumn("RPM", typeof(string)));
DtMotor.Columns.Add(new DataColumn("UniqDevice", typeof(string)));
loadatfirst = 1;
StaticDatatable = NonStaticDatatable ;
}
so, at this point it seems to be no problem, so I have a static function that adds information to the StaticDatatable
StaticDatarow = StaticDatatable.NewRow();
StaticDatarow [0] = numeromotor.ToString();
StaticDatarow [1] = d.FriendlyName;
StaticDatarow.Rows.Add(StaticDatatable);
The problem comes, after this… Im trying to pass the data to the non static table just even up the to tables with a simple
NonStaticDatatable = StaticDatatable;
So if a new user enters the page, the nonstatictable creates as a new object but when its going to repaint the info, pass the information to the static, so if its repeted it doesn’t add in the first place, so it supposed that the only data it would be the new and the old, but no repeted data,
But when a new users enter nothing happened, the data table is empty, and I don’t know why…
[code]
public static DataTable StMotor = new DataTable();
public static DataRow SrMotor;
public DataTable DtMotor = new DataTable();
public DataRow DrMotor;
public void generategrids()
{
MotorsGrid.DataSource = CreateDataMotor();
MotorsGrid.DataBind();
}
protected ICollection CreateDataMotor()
{
if (loadatfirst == 0)
{
DtMotor.Columns.Add(new DataColumn("Numero", typeof(string)));
DtMotor.Columns.Add(new DataColumn("Nombre", typeof(string)));
DtMotor.Columns.Add(new DataColumn("Estado", typeof(string)));
DtMotor.Columns.Add(new DataColumn("RPM", typeof(string)));
loadatfirst = 1;
StMotor = DtMotor;
}
/*
StMotor.Columns.Add(new DataColumn("Numero", typeof(string)));
StMotor.Columns.Add(new DataColumn("Nombre", typeof(string)));
StMotor.Columns.Add(new DataColumn("Estado", typeof(string)));
StMotor.Columns.Add(new DataColumn("RPM", typeof(string)));
StMotor.Columns.Add(new DataColumn("UniqDevice", typeof(string)));
* */
DataView dv = new DataView(DtMotor);
return dv;
}
private static void FuncMotor()
{
bool repetido= false;
for (int i = 0; i <= numeromotor-1; i++)
{
if ((string)d.UniqueDeviceName == (string)CpSMotor.MotorUnique[i])
{
repetido = true;
}
}
if (repetido == false)
{
numeromotor++;
SrMotor = StMotor.NewRow();
SrMotor[0] = numeromotor.ToString();
SrMotor[1] = “info”;
SrMotor[2] = “info”
SrMotor[3] = “info”; //test
SrMotor[4] = “info”;
StMotor.Rows.Add(SrMotor);
}
}
protected void refrescar_Click(Object sender, EventArgs e)
{
//DtMotor.Merge(StMotor, false);
DtMotor = StMotor;
for (int i = 0; i < DtMotor.Rows.Count; i++)
{
DtMotor.Rows[i].BeginEdit();
DtMotor.Rows[i][2] = “info2”
DtMotor.Rows[i][3] = “info2”
}
DataView dv = new DataView(DtMotor);
MotorsGrid.DataSource = dv;
MotorsGrid.DataBind();
}
[/code]
the issue is, I need the data form the code behind object, be the same for al the users, cause the page automaticlly request for new information throug a java timer, so when a modify data appears the code behind update on the data table, and pass it to the dataview in order to be repainted when the request comes.

Use the Cache on the first read to cache the data and then retrieve it from their there for your other users.
