I want to combine the FormCode and AutomaticAdvance rotator types - telerik

Question

How can I create a rotator with "FormCode" mode while being able to start that rotator automatically when the page loads? In other words, to start the rotator automatically while enabling end user to stop/start/move next/move back.
I need a complete sample code for the call.
I've used the following JavaScript/JQuery code for FormCode management:
<script type ="text/javascript">
//
function
startRotator(clickedButton, rotator, direction)
{
if
(!rotator.autoIntervalID)
{
refreshButtonsState(clickedButton, rotator);
rotator.autoIntervalID = window.setInterval(
function
()
{
rotator.showNext(direction);
}, rotator.get_frameDuration());
}
}
function
stopRotator(clickedButton, rotator)
{
if
(rotator.autoIntervalID)
{
refreshButtonsState(clickedButton, rotator)
window.clearInterval(rotator.autoIntervalID);
rotator.autoIntervalID =
null
}
}
function
showNextItem(clickedButton, rotator, direction)
{
rotator.showNext(direction);
refreshButtonsState(clickedButton, rotator);
}
// Refreshes the Stop and Start buttons
function
refreshButtonsState(clickedButton, rotator)
{
var
jQueryObject = $telerik.$;
var className = jQueryObject(clickedButton).attr("class"
);
switch
(className)
{
case "start"
:
{
// Start button is clicked
jQueryObject(clickedButton).removeClass();
jQueryObject(clickedButton).addClass(
"startSelected"
);
// Find the stop button. stopButton is a jQuery object
var stopButton = findSiblingButtonByClassName(clickedButton, "stopSelected"
);
if
(stopButton)
{
// Changes the image of the stop button
stopButton.removeClass();
stopButton.addClass(
"stop"
);
}
}
break
;
case "stop"
:
{
// Stop button is clicked
jQueryObject(clickedButton).removeClass();
jQueryObject(clickedButton).addClass(
"stopSelected"
);
// Find the start button. startButton is a jQuery object
var startButton = findSiblingButtonByClassName(clickedButton, "startSelected"
);
if
(startButton)
{
// Changes the image of the start button
startButton.removeClass();
startButton.addClass(
"start"
);
}
}
break
;
}
}
// Finds a button by its className. Returns a jQuery object
function
findSiblingButtonByClassName(buttonInstance, className)
{
var
jQuery = $telerik.$;
var ulElement = jQuery(buttonInstance).parent().parent();
// get the UL element
var allLiElements = jQuery("li", ulElement);
// jQuery selector to find all LI elements
for (var
i = 0; i < allLiElements.length; i++)
{
var
currentLi = allLiElements[i];
var currentAnchor = jQuery("A:first", currentLi);
// Find the Anchor tag
if
(currentAnchor.hasClass(className))
{
return
currentAnchor;
}
}
}
//]]>
And the following code for the calls:
<
a href="#" onclick="stopRotator(this, $find('<%= MyRotator.ClientID %>
')); return false;"
class="stopSelected" title="Stop">Stop
'), Telerik.Web.UI.RotatorScrollDirection.Left); return false;"
class="start" title="Start">Start
However, I cannot start the rotator on the page load. Tried to use this code in the in the MyRotator_DataBoud event, but did not work either:
protected void rrMyRotator_DataBound(object sender, EventArgs
e)
{
Page.RegisterClientScriptBlock(
"MyScript", " startRotator(this, $find('<%= MyRotator.ClientID %>'), Telerik.Web.UI.RotatorScrollDirection.Left);"
);
}

There are a couple of examples available in the Telerik online demos for this functionality and they have code you can use. See http://demos.telerik.com/aspnet-ajax/rotator/examples/clientapicontrol/defaultcs.aspx and http://demos.telerik.com/aspnet-ajax/button/examples/slideshow/defaultcs.aspx
