    We're using the following code to print the content of a radpane :
    But the newly opened window does not close itself after printing.
    Is there any way to achieve this behaviour?
    function clientButtonClicking(sender, args) {
                       var toolBar = sender;
                       var button = args.get_item();
                       if (button.get_value() == "print") {
                           var splitter = $find('<%= RadSplitter2.ClientID%>');
                           var pane = splitter.GetPaneById('<%= RadPaneContentDetail.ClientID %>');
                           if (!pane) return;
                       }                    }

    Hi Chris,

    By design the RadPane's print() method is implemented on the base of the default window.print() method.

    Unfortunately, it does not dispose a way to access (and respectively to close) the opened print window. The only possible way to achieve it is by overwriting the RadPane's print() by adding the desired closing functionality.

    For instance, you could achieve it in a similar way:
    Telerik.Web.UI.RadPane.prototype.print = function(arrCssFiles)
        /// <summary>
        /// print the content of the pane. If the pane is not displaying
        /// external content the printed content will be formatted using the specified cssFiles.
        /// </summary>
        var sFeatures = 'width=' + this.get_width() + 'px, height=' + this.get_height() + 'px, scrollbars=1';
        var previewWndUrl  = (this.isExternalContent()) ? this.get_contentUrl() : 'about:blank' ;
        var previewWnd = window.open(previewWndUrl, '', sFeatures, false);
        if (this.isExternalContent())
                var t = function() {
                setTimeout(t, 1000); // wait until the content is loaded
            } catch(e) {}
        var styleStr = "";
        if (arrCssFiles) {
            styleStr = "<head>";
            for(var i=0, length=arrCssFiles.length; i < length; i ++)
                styleStr += "<link href = '" + arrCssFiles[i] + "' rel='stylesheet' type='text/css'></link>"
            styleStr += "</head>";
        var popupContent = styleStr + "<body>" + this.get_content() + "</body>"
        previewWnd.onfocus = function(){previewWnd.close()};

    Please, note that the script, which is overwriting the RadPane's print() function, has to be placed inside the <form> tag (recommended just before the closing </form> tag).
