How can I let users paste '123456  ' into my numeric textbox and have it auto-strip the spaces? The spaces are usually at the end but are possibly at the beginning too.

Currently unless I copy/paste all digits nothing gets pasted. I can see it trying to paste but then it automatically disappears.

@(Html.Kendo().NumericTextBoxFor(model => model.DocumentId)
.Spinners(false).Decimals(0).Format("#")

)

Perhaps there's a property to help me do this or an event where I can reliably get the pasted value, strip all but the digits and replace the text before any validation occurs.

Hi Adam,

The behavior you describe would require custom logic. You can handle the paste event of the input element and access the data stored in the clipboard. 

If you would like additional information on accessing the clipboard you would find the stackoverflow thread below interesting.


For your convenience I assembled a small dojo example that outlines the approach. Check it out below:
