In my project have requirement to export chart into png format.Is it possible in kendo-ui with out using ink-space(3rd party tool)?
It is possible if you know how to convert SVG to PNG (the Kendo Chart doesn't provide this out of the box). Inksape is an open source tool which can convert SVG to various formats. However you must not use it for some reason you can check this .NET SVG rendering library: http://svg.codeplex.com
