Enhancing Pages with AJAX Control Toolkit
The AJAX Control Toolkit is a collection of ASP.NET AJAX extensions that provide additional functionality to ASP.NET web pages. Some of the controls included in the toolkit are the Accordion, AutoComplete, Calendar, ModalPopup, and TabContainer controls.
Here’s an example of how to add an AJAX Accordion control to a web page:
Add a reference to the AJAX Control Toolkit to your project. You can download the toolkit from the official website or use NuGet package manager to install it.
In your web page, add the following code to the <head> section:
<%@ Register Assembly=”AjaxControlToolkit” Namespace=”AjaxControlToolkit” TagPrefix=”ajax” %>
This registers the AJAX Control Toolkit namespace and tag prefix with your web page.
Add an Accordion control to your web page:
<ajax:Accordion ID=”myAccordion” runat=”server”>
<Panes>
<ajax:AccordionPane ID=”pane1″ runat=”server” HeaderText=”Pane 1″>
<!– Content for pane 1 –>
</ajax:AccordionPane>
<ajax:AccordionPane ID=”pane2″ runat=”server” HeaderText=”Pane 2″>
<!– Content for pane 2 –>
</ajax:AccordionPane>
<ajax:AccordionPane ID=”pane3″ runat=”server” HeaderText=”Pane 3″>
<!– Content for pane 3 –>
</ajax:AccordionPane>
</Panes>
</ajax:Accordion>
This creates an Accordion control with three panes. Each pane has a HeaderText property that specifies the text to display in the pane header, and the content of the pane is defined inside the AccordionPane tag.
You can customize the appearance of the Accordion control by adding CSS styles. For example:
<style type=”text/css”>
.accordionHeader {
background-color: #E8E8E8;
padding: 5px;
border: 1px solid #C0C0C0;
font-weight: bold;
}
.accordionContent {
padding: 10px;
border: 1px solid #C0C0C0;
}
</style>
This defines two CSS styles for the Accordion control: one for the header (accordionHeader) and one for the content (accordionContent).
You can also add behaviors to the Accordion control, such as expanding or collapsing a pane when the user clicks on it. For example:
<ajax:Accordion ID=”myAccordion” runat=”server”>
<Behaviors>
<ajax:AccordionBehavior HeaderCssClass=”accordionHeader” ContentCssClass=”accordionContent” />
</Behaviors>
<Panes>
<ajax:AccordionPane ID=”pane1″ runat=”server” HeaderText=”Pane 1″>
<!– Content for pane 1 –>
</ajax:AccordionPane>
<ajax:AccordionPane ID=”pane2″ runat=”server” HeaderText=”Pane 2″>
<!– Content for pane 2 –>
</ajax:AccordionPane>
<ajax:AccordionPane ID=”pane3″ runat=”server” HeaderText=”Pane 3″>
<!– Content for pane 3 –>
</ajax:AccordionPane>
</Panes>
</ajax:Accordion>
This adds an AccordionBehavior to the Accordion control, which specifies the CSS classes for the header and content sections.
