asp.net timer not firing the updatepanel

I have a table within my aspx page content page (using a Master Page also)
The problem is the Timer doesn't seem to be doing the async postback it doesnt even hit the method
I've tried a fresh solution in VS with the below code and it works fine every 10 seconds the event updatepanel is refreshed. So I believe the code is fine but there's something stopping this from working and I can't figure what.

code behind
protected void TimerPrayer_Tick(object sender, EventArgs e)
{
ReadMyData();
}

I had the same problem. I put a timer inside my update panel. It was not firing its OnTick event callback at all.
I moved the timer outside the update panel and then it started firing on the callback.
Then I added a Trigger for the timer in the update panel and it works:
<asp:UpdatePanel ID="UpdatePanelChart" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="tmChartPanel"
EventName="Tick" />
</Triggers>
<!-- ... -->

I had this in my page load which was stopping the postback
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "setDOM", "$(\"#divDigitalClock\").clock({ \"langSet\":\"en\",\"format\":\"24\"});", true);

Maybe you can use trigger.Because update panel postback works with trigger.
You don't have to use timer in update panel,use timer outside the update panel.
And as an example using timer in update panel
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
</Triggers>
<ContentTemplate>
<!-- your content here, no timer -->
</ContentTemplate>
</asp:UpdatePanel>
<asp:Timer ID="Timer1" runat="server" Interval="5000" OnTick="Timer1_Tick">
</asp:Timer>
source of code

Textfield clears after calendar control postback

I have 3 text fields on my page and one calendar control. After I fill in the 3 text boxes, then click a date on the calendar control, the bottom textfield clears out, losing its value. The other 2 text boxes have their values available and do not get cleared. The textboxes all have the same properties, but I can't figure out how to keep the value in the third textbox.

but this works only when i click somewhere out (take focus off the searching control)and then hit enter
Please suggest

You can place your controls inside a asp:panel and set it's default button.
<asp:Panel ID="p" runat="server" DefaultButton="myButton">
<%-- Text boxes here --%>
<%-- drop down here --%>
.....
<asp:Button ID="myButton" runat="server" />
</asp:Panel>

set a default button to be clicked when the user presses Enter? Simply add the following line to your page's Load event, replacing "btnSearch" with the name of your button. It uses a hidden Page method called RegisterHiddenField and works splendidly:
Page.RegisterHiddenField("__EVENTTARGET", "btnSearch")
Source :-Default Button

try using Button and its UseSubmitBehavior
<asp:Button ID="btnSearch" runat="server" Width="125" Height="45" UseSubmitBehavior="true" />
instead of Image button.
You can easily set the background image of button using css. so don't use Image Button

Place this script below the scriptmanager:
<script type="text/javascript">
var $p = Telerik.Web.UI.RadComboBox.prototype;
var keyDownHandler = $p._onKeyDown;
$p._onKeyDown = function (e) {
var oReturnValue = e.returnValue;
var oPreventDefault = e.preventDefault;
var keyCode = e.keyCode || e.which;
if (keyCode === 13)
e.preventDefault = null;
keyDownHandler.call(this, e);
if (keyCode === 13) {
e.returnValue = oReturnValue;
e.preventDefault = oPreventDefault;
}
};
</script>
