How to get Image width and height on upload image?

[Adil]

Hi Telerik Family,

I have kendo upload and i'm uploading some image and video with  that . I need to check image width and height of image so than i can understand image is proper or not proper.

I checked you have "e.files[0].size" value for .Select() event but that is not useful for me.

 

What you suggest?

 

Thanks

Hello Adil,

You can create a new Image() object from the raw file, available in the event data in the Upload's Select event handler. Then you can access its naturalHeight and naturalWidth properties.

Details are available in online resources not specifically related to UI for ASP.NET MVC, since this is not a functionality that's built-in in our Upload:
