This value may indicate that the application is compromised.ProgramSecurity attempts, such as cross-site scripting attacks. To allow the page to override the application request verification settings, set the requestvalidationmode feature in the httpruntime configuration section to requestvalidationmode = "2.0 ". Example: />.After setting this valueYou can disable request verification by setting validaterequest = "false" in the page command or <pages> Configuration section. However, in this case, it is strongly recommended that the application explicitly check all input.

<Configuration>   
     <System. Web>

        <Httpruntime requestvalidationmode = "2.0" type = "codeph" text = "/codeph"/>  // Indispensable
         <PagesValidaterequest = "false"/>   
     </System. Web>   
</Configuration>

 

 

Method 2: Add the following on the. ASPX page:    
<% @ PageValidaterequest = "false" %>

 

Pagessection. validaterequest attributes
