Hello,

You can use the Kendo UI Drwaing library for achieving the required functionality. For example:

var that = $find("RadTreeList1");

var kendo = window.kendo;

var $printingContainer;

if ($telerik.isIE || Telerik.Web.Browser.edge) {

var printWindow = window.open();

if (!printWindow) return false;

$printingContainer = $telerik.$("<div>");

kendo.drawing.drawDOM(that.get_element()).then(function (group) {

return kendo.drawing.Surface.create($printingContainer, { type: "svg" }).draw(group);

}).done(function (data) {

var html = "<html><head>" + that._getHeadLinksForPrint() + "</head><body><form style='height:" + that.get_element().scrollHeight + "px;'>" +

$printingContainer.get(0).innerHTML + "</form></body></html>";

printWindow.document.open();

printWindow.document.write(html);

printWindow.document.close();

printWindow.print();

$printingContainer.remove();

});

} else {

kendo.drawing.drawDOM(that.get_element())

.then(function (root) {

return kendo.drawing.exportPDF(root);

})

.done(function (data) {

window.open(data, '', false);

});

}

Give this a try and verify if it works for you.

This does work when fewer items need to be printed in a collapsed state and the page size is less than 1, but the screen is blank when trying to print data after expanding all the nodes. I have attached both the screenshots below. I need to be able to print about 600 to 1000 rows sometimes. How do I make this work for large amounts of data?
