its working in sitefinity 3.7 but i need in 4.2 plz give solution for that.here  WebUITypeEditor<string>  didnt work.

Hi Mari,

Sitefinity 4.x API model is very different from 3.7. Instead of WebUITypeEditor<string> you should use SimpleView. Please check the following blog posts that outline how to create a custom widget for Sitefinity 4.x

Hi Mari,

Could you send us the whole code that you have - the .cs designer, any .ascx template and the Javascript. Having this piece of Javascript code out of context isn't helping much.
