postback via java for TextBox

[aussie1968]

hi,

i need to be able to find out when the user changes a date, which is displayed in a textbox using a CalendarExtende r.
because the CalendarExtende r only allows client side (java) calls and does not call a function in code behind, i have to somehow find a way to do this using java.
i would like to use the OnTextChanged event of the textBox if possible.
i have got most of the code, but i do not know how to retrieve the targetID object of the CalendarExtende r.
i must admit, my java knowledge is not the best and i can not find any info on it.

here the code


<script type="text/javascript">
function UpdateClientDat e(cal)
{
__doPostBack(>> >textBoxObj<<<, 'test');
// textBoxObj is supposed to be the TargetControlID of CalendarExtende r1
// obj of CalendarExtende r1 should be the parameter cal, right ?
}
</script>

...
<asp:TextBox ID="IDE_DATE_FR OM" runat="server" Width="75px" OnTextChanged=" IDE_DATE_FROM_T extChanged"></asp:TextBox>
<ajaxToolkit:Ca lendarExtender ID="CalendarExt ender1" runat="server" Format="dd/MMM/yyyy" OnClientDateSel ectionChanged=" UpdateClientDat e" TargetControlID ="IDE_DATE_FROM " />
...


code behind

protected void IDE_DATE_FROM_T extChanged( object sender, EventArgs e )
{
}


any help would be appreciated

cheers

__doPostback might not be the right way to go if i want to use an event ;)
the follwing function should be more suitable, but i still need to retrieve the obj of the textBox.

function FireEvent(el, ev)
{
var localE = document.create Event("HTMLEven ts");

localE.initEven t(ev.substring( 2, ev.length), true, true);
el.dispatchEven t(localE);
}

since i am using this in a gridView with a dynamic amount of rows, i guess i can
not use the follwing either.

$get('ctl00_Con tentPlaceHolder 2_IDE_DATE_FROM ');

Martin,

You may call

document.getElementById(<%=IDE_DATE_FROM.Idclient%>)
