Crystal Report : Nothing appears in crystal report

问题

I am using Crystal Report Version=13 in my Web Application using Asp.Net. My reports were working fine, i don't remember what changes i have made, due to which the report is not showing data, even Design is not shown of report. When i open report and refresh it, in Fire Bug i got the below error.

bobj.crv.stateManager.setComponentState('CrystalReportViewer1__UI',eval('('+document.getElementById('__CRYSTALSTATECrystalReportViewer1').value+')'));

Any one have experience of such type of error.

I got the solution, i have disabled ViewState on my Application in web.config, by enabling it, its working.

<pages enableViewState="true" >
