I have a checkbox inside a datalist control with
Autopostback="True". When a user clicks the checkbox the associated
event Handler is not firing.

My code is


<asp:DataList ID="myDataList" runat="server"
RepeatColumns="1" RepeatDirection="Vertical" >
<ItemTemplate> <asp:CheckBox ID="chkid"
runat="server" autopostback="True" /> <%#"Id "
+ Container.DataItem("CustomerID")%><br />
<%#"Name " + Container.DataItem("ContactName")%>
<br /> <br />
</ItemTemplate> </asp:Da

I have an onkeydown event that may or may not scroll the page, and
may or may not set a variable. I would like to have an onscroll event
that sets that variable to false. I do not want the onkeydown event to
trigger the onscroll event. How can I do this?

edit: Added my code. It lets you use your left and right arrow keys
to move up and down through the images on my page. Sorry it's so

window.anImageHasBeenCentered = false;

window.onkeydown = function ( key )
var element = document.elementFromPoint ( window.innerWidth /
2, window.innerHeight / 2 );

if ( anImageHasBeenCentered ) // move to next image
switch ( window.event ? event.keyCode : key.keyCode )
case 37: element =
element.parentNode.previousSibling.previousSibling.firstChild; break;
// Left Arrow
case 39: element =
element.parentNode.nextSibling.nextSibling.firstChild; break; // Right
default: anImageHasBeenCentered = false; element =

else // center current image
switch ( window.event ? event.keyCode : key.keyCode )
case 37: break; // Left Arrow
case 39: break; // Right Arrow
default: element = null;

if ( element )
element.scrollIntoView ( );

if ( ( window.innerHeight + window.scrollY ) <
document.body.offsetHeight ) // if we are not at the bottom of the
if ( element.offsetHeight < window.innerHeight ) //
if the element is shorter than the screen
{ window.scrollBy ( 0, -( ( window.innerHeight -
element.offsetHeight ) / 2 ) ) } // position it in the middle of the

anImageHasBeenCentered = true;

// The function I would like to add, that is unfortunately
triggered by the onkeydown function.
// window.onscroll = function ( ) { anImageHasBeenCentered =
false; }

I have a asp.net control that references a user control(popup) when
a button is pressed. When the button is pressed I find the drop down
list in the popup user control and I set the selected value of it.

  protected void btnMyBUtton_Click(object sender, EventArgs

if (ddParent.SelectedIndex > 0)
DropDownList dd =
ucMyControl.FindControlRecursive("ddChild") as DropDownList;

dd.SelectedValue = ddParent.SelectedValue;


In the popup user control I'm expecting the SelectedIndexChanged
event to fire. However, it isn't. Any ideas why this would be the

Markup for my child control(only relevant code) is below:

<asp:FormView ID="myForm" runat="server"
DataSourceID="dsMyDS" DefaultMode="Insert">
<asp:Panel runat="server">

<asp:Label Text="Name" runat="server"
<asp:DropDownList ID="ddChild" runat="server"
DataSourceID="ddDS" DataMember="" DataValueField="Id"
DataTextField="Name" SelectedValue='<%# Bind("Id") %>'
OnDataBound="ddChild_DataBound" />

<br />
<asp:Button ID="btInsertOk" runat="server"
Text="Add" CommandName="Insert" />
<asp:Button ID="btInsertCancel" runat="server"
Text="Cancel" />

Thanks in advance.

I have two objects (A and B) that collide, and when they do, they
each fire the TriggerEnter2D event.

  • Object A takes damage when this happens.

  • Object B destroys itself.

I have noticed that in this model, the damage taken by Object A is
intermittent. Sometimes it takes damage, other times it does not.
This is due (seemingly) to Object B destroying itself before Object A
counts its damage. At least, when I comment out the Destroy method,
all the damage gets counted correctly. This is a problem of timing,
and is the kind of bug that freaks me out a bit because it's

Since I'm new to Unity, is there a best practice on handling the
architecture of two interacting objects like this? This must be a
very common case. The tutorials I've seen seem to use publicly
exposed properties of the other object (say object A) from within the
handling object (object B).

Thus, I would have only one handler on Object B that would then
call a public method on Object A to say "you were damaged". Is this
best practice?

I am trying to build a DateTimePicker Widget and do not want to
worry about the instantiation of the widget so I have created a
Can.Control which takes the html body as the element.

But, now my input elements are rendered in the DOM using can.view.
How do I bind an event to the insertion of a new dateTime element to
my control scope?

* DateTime Plugin

plugins.DateTime = can.Control.extend({

init : function ( element , options ){

'input.dateTime click' : function (){
$( this.element ).find('input.dateTime').datetimepicker();
new plugins.DateTime('body');

Is there any way I can specify 'input.dateTime load' to bind a
datepicker when the element is added to the control element?
