How
to use Validation in Asp.Net with IDE Visual Studio 2012....................
Note: When we will apply validation on WebPages in
Asp.Net with Visual Studio 2010 IDE or earlier version like (2008,2005)
there is no problem with to validation , but with Visual Studio 2012,13 IDE , there occurs
some errors with validation, the error
is being …..
Server Error in '/' Application.
WebForms
UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please
add a ScriptResourceMapping named jquery(case-sensitive).
The solution to the
problem is to make some changes in Web.Config
which I have provided as follows….
<?xml version="1.0"?>
