Id of my control

[simon]

I have my user control and inside that control I have textBox:

<asp:TextBox Runat=server AutoPostBack=True ID=txtListBox
onkeydown="filter()"></asp:TextBox>
<script language="vbscript">
sub filter
msgbox document.getElementById("txtListBox").value
end sub
</script>
The id of my textBox is txtListBox.

Than I use my control on the page:

<%@ Register TagPrefix ="CustomListBox" TagName = "orders" Src =
"userControls\customListBox.ascx"%>
<CustomListBoxrders runat="server" id="order1"></CustomListBoxrders>

and when the page is rendered I get input box:

<input name="order1:txtListBox" type="text"
onchange="__doPostBack('order1$txtListBox','')" language="javascript"
id="order1_txtListBox" onkeydown="filter()" />

The id of this input is not "txtListBox" but "order1_txtListBox" so my
script won't work.

How can I solve this problem?

Thank you,
Simon

I may be wrong, but could you pass the filter sub a reference to the control calling it. I've done it in javascript before, I guess you could do it in vbscript as well. do something like this:

....onkeydown="filter(this)" or in vbscript it may be "filter(me)"

sub filter(control)
msgbox control.value
end sub

One solution is to output your script dynamically from server side code and
use txtListBox.ClientID to determine what the ID is at runtime.

You might find the RegisterClientScriptBlock method useful:
