How can i trap the onkeypress event of an server side text box ? I tried
with the following code.
<script language=vb runat="Server">
Sub press(Sender as Object,E as EventArgs)
End Sub
</script>
<form runat=3D"server">
<input type=3Dtext id=3D"txt1" runat=3D"server" OnkeyPress=3D"Press"/>
</form>
When i raise that event by pressing a key in the text box an runtime
error flashes stating cannot find the specifed method(Press).
Please mail me the exact syntax to handle the keypress event.
Regards
SATHISH C.G.

Sathish,
OnKeyPress is a *client* side event in the browser, and the function that
handles it ("Press" in your case) needs to be in client script in a
client-side script block. If this is already working for you, adding
runat="server" to your input tag should not change this.
Your example shows trying to handle the keypress on the server, which is not
supported.
hth,
Susan

Hai,
Hi,
Thanks for the solution.But what about the OnKeypressEventArgs Object.
Can we pass the object in the event handler to get the key code or we have
to use the traditional way (WIndow.Event.KeyCode).
regards
SATHISH C.G.

Sathish,
The KeyPressEventArgs class is part of the Windows Forms forms package
framework (you'll note it's in the System.WinForms namespace), not part of
ASP.NET. Processing for .NET classes in an ASP.NET form takes place on the
server -- it has to, in order to work with Web clients that don't have .NET
installed on them.
If you are creating a traditional client application, and .NET will be
installed on the client, then you should check out Windows Forms.
hth,
Susan

You mean KeyPressEventArgs ?
You can use the KeyChar property of the KeyPressEventArgs, it return the
character corresponding to the key pressed.
This will work only for Windows Forms.
Here is an example:
Public Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As
System.WinForms.KeyPressEventArgs) Handles TextBox1.KeyPress
MessageBox.show(e.KeyChar())
End Sub

Hi,
Can we use windows form controls in a .aspx page. Can we use functions
like msgbox.show in a .aspx file. Please tell me the exact difference
between win forms and web forms.

Win forms is an object model for windows which sits on
top of NGWS which sits on top of Win API etc.
Web forms are essentially a suite of objects enabling
HTML output which the browser can interpret. Such that
somebody can write a web control and package it up
using it anywhere within an NGWS environment (in an
ASP.NET context). This introduces the idea of
component reusability with respect to the web. The
outout of which will always be HTML (currently HTML
3.2).

Richard
