In reference to the
Issue presented at Asma's Blog. Here is my solution i.e. Issue is not in the code. IIS server has query request limit on GET method. So, do the following in your web.config file which will resolve the issue i.e.
.....
<system.web>
<authentication mode="None" />
<compilation debug="true" targetFramework="4.5.2" />
<!-- maxQueryStringLength= the value is in Character and maxUrlLength= the value is in Character -->
<httpRuntime targetFramework="4.5.2" maxQueryStringLength="65536" maxUrlLength="65536" />
</system.web>
<system.webServer>
<!-- maxQueryString = 1GB (the value is in Bytes) -->
<security>
<requestFiltering>
<requestLimits maxQueryString="1073741824" />
</requestFiltering>
</security>
.....
</system.webServer>
.....
Sample
Web.config file.
You will be then able to add more columns i.e...
Thanks & Regards.
