function calling problem

[swapcode]

Hi,
i m trying to close web form by creating
function fclose()
{
window.close ;
}
and calling this function by
<asp:Button id="Button2" runat="server" Text="cancel" OnClick = "fclose()"></asp:Button>

but somehow its giving compilation error as
'fclose' is not a member of 'ASP.WebForm1_aspx'.
pls tell me how to solve this problem?

1) by default your function is private 2) it looks like you're mixing and matching VB and C# code.

Here is a C# example

public void fclose()
{
// your code
}

I have no clue what window.close does in this case, but chances are it's a function and not a property so you'd want window.close(); and not window.close;

You can't call a client side script directly with an asp.net button. Either switch the button type to a standard input button or add the javascript as a client side attribute.

add onclick attribute to the client

//Page_Load
Button.Attributes.Add("onclick","window.close()");

Adding to what mmetzger said:

Here's a nice example

but i think the onclientclick is only available for .net ver 2 but i have 1.1

so that attribute not working here...

but i think the onclientclick is only available for .net ver 2 but i have 1.1

it doesn't relate to .NET,it is a javascript attribute.
onclientclick? not heard that befor,I think you meant onclick attribute.

[Eli Gassert]

OnClientClick is a .NET 2.0 attribute because OnClick relates to .NET functions with ASP.NET controls, whereas with a normal HTML control onclick relates to a javascript call.

The .NET 2.0 solution: have OnClick work like OnClick in 1.0 (.NET related) and add the OnClientClick attribute which will relate back to a javascript onClick event. No more having to use the .Attributes.Add() method mentioned above, everybody wins

oh yeah, .NET 2 makes things simpler for developers
another way..

public class ButtonClosing:System.Web.UI.WebControls.Button
 {
  protected override void OnPreRender(EventArgs e)
  {
   base.OnPreRender(e);
   this.Attributes["onclick"]="window.close()";
  }
 }

hey,
Why did you override PreRender function?

[mehdi62b]

hey,
Why did you override PreRender function?

well,because the order of events is,
init,load,[other events],prerender,unload which ulnload would be fired off after loading the page with no affect...so prerender is the best place for adding the attribute.
