Printing Content

You can print the content of a RadPane control using its client-side API. The RadPane client-side object has a print() method that prints the content of the pane.

  • If the content of the pane comes from an external source, the URL must be from the same domain as the splitter parent page. Otherwise, the pane cannot print its content due to security restrictions of the browser.

  • If the pane is not displaying external content, you can specify a stylesheet which will be used to format the printed content.

Example

The following example demonstrates how to print the content of a pane:

<telerik:RadSplitter RenderMode="Lightweight" id="RadSplitter1" runat="server" height="200">
 <telerik:RadPane id="InternalContentPane" runat="server" width="120">

   </p>
 </telerik:RadPane>
 <telerik:RadSplitBar id="RadSplitbar1" runat="server"/>
 <telerik:RadPane id="ExternalContentPane" runat="server" width="300"
    ContentUrl="Default.html" />
</telerik:RadSplitter>
<a href="javascript:PrintPane('<%= InternalContentPane.ClientID %>');">
 Print the content of 'Internal Content Pane'</a><br />
<a href="javascript:PrintPane('<%= ExternalContentPane.ClientID %>');">
 Print the content of 'External Content Pane'</a>
<script type="text/javascript">
    function PrintPane(paneID)
    {
        var splitter = $find('<%= RadSplitter1.ClientID%>');
        var pane = splitter.GetPaneById(paneID);
        if (!pane) return;
        var cssFileAbsPath = 'http://localhost/printStyles.css';
        var arrExtStylsheetFiles = [cssFileAbsPath];
        pane.Print(arrExtStylsheetFiles);
    }
</script> 

Printing Telerik controls in the content of a RadPane

If there are Telerik controls in the content of a RadPane you should add the CSS files that decorate the controls to the array, containing the external stylesheets. Below you can find a modified version of the PrintPane function that includes the Telerik controls CSS files, linked on the page, and adds them to the arrExtStylsheetFiles array.

<script type="text/javascript">
    function PrintPane(paneID) {
        var splitter = $find('<%= RadSplitter1.ClientID%>');
        var pane = splitter.GetPaneById(paneID);
        if (!pane) return;

        var arrExtStylsheetFiles = getTelerikCssLinks();

        pane.Print(arrExtStylsheetFiles);
    }

    function getTelerikCssLinks() {
        var result = new Array();

        var links = document.getElementsByTagName("LINK"); //get all link elements on the page

        for (var i = 0; i < links.length; i++) {
            if (links[i].getAttribute("class") == "Telerik_stylesheet")//check if the link element is a Telerik Stylesheet
                result.push(links[i].getAttribute("href", 2)); //add link href attribute to the result
        }

        return result;
    }
</script>
