At. Mr. Darmendr
After adding the package recommended by you to VS 2012, it can be seen in the ASP.Net solution explorer that I am trying to create a new Scripts folder with several js extension files and a new pakages.config file. On the other hand, it recommends me to drag the js and css Content files to the web page (withdraw.aspx) where I try to select a date for the textbox (txtFe), however I cannot find the Content.
Perhaps, if I study other similar cases on the web, I will better understand this insertion and uses of java control packages, and achieve what I intend. To date I have only programmed with Win Forms under the Visual Basic 2010 environment, although now I try to operate on web pages, via ASP.Net from VS 2012 and its corresponding withdraw.aspx.vb for example.
Thank you and take care
