Hi...

I am making a website in asp.net using c#. I want to give functionality of downloading a file. For dat i tried using SaveFileDialog in codebehind as under.

SaveFileDialog DialogSave = new SaveFileDialog();
if (DialogSave.ShowDialog() == DialogResult.OK)
{
}
else
{
}

Bt wen comparing if condition, it gives me following error.

"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process."

Can someone tell me the way to use this SaveFileDialog or some other way to achieve this functionality.

Just redirect to the file which you would like your users to download. Say you have a file in files directory. To download it, Response.Redirect("files/yourfilename.extension")

You are lost completly. Take some good books on ASP.NET and learn how it works. SaveFileDialog is commonly used in stand-alone applications not in ASP.NET.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

If you do this, you're trying to display the save file dialog on the server, not the client. Not going to work.

If you send a file to a web browser, it will automatically try to give you the option to save it if it's not a recognised html file.

Try this

Javascript :

__doPostBack('RAISE_Your_Event','specify_argument_here_if_needed');

ASPX.CS Page_Load Event:

if (this.IsPostBack)
{
    // Insure that the __doPostBack() JavaScript method is created...
    this.GetPostBackEventReference(this, string.Empty);

    string eventTarget = (this.Request["__EVENTTARGET"] == null) ? string.Empty : this.Request["__EVENTTARGET"];


    if (eventTarget == "RAISE_Your_Event")

Hello everyone,

I am using loadcontrol method to load custom controls.
I have a single .aspx page and a left menu (.ascx control) which is loaded dynamically.
When i click on the left menu's link, control is loaded accordingly.
The problem is:
Loadcontrol always loads control with ispostback=true.
It happens bcoz i have used __doPostBack() onclick of the leftmenu's link.
I want the ispostback = false in the control's load event.
Any help is always welcome.

Thanks,

Malay Khandhediya.

Try using the Header Template for the headers where you can customize the view of the headers.

Or if you have the data come from different data source and one is depenedent on the other try using a repeater for the main data then a grid view for each repeated item. But I am not sure this is your case.

Why the apostrophes? An alphanumeric string should not contains apostrophes, should it?
