The following example demonstrates how to use the slideshow extender.

Add a page to the website and then place a ToolkitscriptManager on it & then a panel & design the panel as follows.

Within the HTML source of the page drag & drop a slideshow extender and set following properties for it.

<asp:slideshowextender  Id=”slideshowExtender” runat=”server” imageDescriptionLableID=”L2” ImageTitleLabelID=”L1”  NextButtonId=”Btnnext”  playButtonText=”play”  playbuttonID=”Btnplay” stopButtonText=”stop” previousButtonID=”btnprev” playinterval=”3000” slideshowservicemethod=”Getimages” usecontextkey=”True” Loop=”true” > </asp:slideshowExtender>

Within the design of the page click on the smart tag and choose “ Add slideshow pageMethod” option that will create a method in the code with the same name as the method name you set for the slide show service method property of the slideshowextender write the following code within that method.

using system.AjaxcontrolToolkit;

public static….

{

return new slide[]

{

new slide(“Image/Desert.jpg” ,”Desert”, “This is Desert Image”);

new slide(“images/Lighthouse.jpg”,”Lighthouse” . “This is lighthouse image”);

new slide(“Images/penguins.jpg”,”penguins”,”This is LighthouseImage”);

new slide(“Images/Tulips.jpg”,”koala”,”This is koala Image”)

};

}

At runtime by default first image will be displayed in image control & by clicking on next button you can move to the next slide, by clicking on previous button you can move the previous slide & by clicking on play button you can play the slideshow at the interval specified with playInteraval property.
