>>What i want is when the user hits the enter button it fires the submit button click event.


that happens automatically when a "Submit" button is there in a form. Where exactly do you want this event?


anyway info on how to do it (in any conrol):

onkeydown="event.keyCode==13?document.forms[0].submit();''">

Known is handfull, Unknown is worldfull

The page is a login page the user selects is code from a drop down list that is populated by sql, He then enters a password and click the submit button if he hits the entre key it removes the password from he password box.
there are three lables, a dropdown box and a submit button on the page.

hi vbkris,
I had the same problem. I was wondering if it possible to handle kexboard events within the form behind: something like that:

sub keyEnterDow (obj as object, e as eventargs)
actions
end sub

it seems it is not... and that I need to use javascript in order to trigger a subroutine with the enter key. If I click the enter key in a normal aspx page it would only cause a postback.

the code you posted is it javascript? I added it to my textbox but it didn't work...

on button click the program checks the password against the sql table and returns a result of 0,1,2 or 3

' test to see if password is filled in
Dim intresult As Integer
If Not pwd.Text = "" Then

'code here will try the password against the user id
SqlCommand4.Parameters("@username").Value = uidddl.SelectedItem.Text
SqlCommand4.Parameters("@password").Value = pwd.Text
SqlConnection1.Open()
SqlCommand4.ExecuteNonQuery()
intresult = SqlCommand4.Parameters("@return_value").Value
SqlConnection1.Close()

Select Case intresult
Case 0
Call selectaddress()
Response.Redirect("index2.aspx")

Case 1
warnlbl.Visible = True
warnlbl.Text = "userid"
Case 2
warnlbl.Visible = True
Case 3
'admin password
Call selectaddress()
Response.Redirect("index.aspx")
End Select
End If

There are two quite simple ways of creating a default button for the page:

1) In the page load event add the following (change the name of btnSearch to the relevant asp button):
Code: 
Page.RegisterHiddenField("__EVENTTARGET", "btnSearch")

2) Use javascript. e.g.
Code: 
<script language="javascript">
    function KeyDownHandler(btn)
    {
        // process only the Enter key
        if (event.keyCode == 13)
        {
            // cancel the default submit
            event.returnValue=false;
            event.cancel = true;
            // submit the form by programmatically clicking the specified button
            btn.click();
        }
    }
</script>

<asp:Button Runat="server" ID="DefButton" />
<asp:TextBox Runat="server" ID="FirstName" onKeyDown= _
    "KeyDownHandler(DefButton)" />

If you go with option 1, then you need to add it in the page load event of the actual page e.g.
Code: 
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Page.RegisterHiddenField("__EVENTTARGET", "btnSearch")
End Sub
If you go with option 2, simply add it to the html as it is javascript.
