Hi, i'm new here and i'm having a serious problem : When i try to print or export my report using the print/exporting crystal report viewer's options , i get a message like : Invalid PostBack, Use the function ClienteScriptManager to register the control event, or try <@Page RegisterEventHandler = true@> I already searched a lot at google, and i saw that many people have this problem, using others .Net controls too. I know now that i have to override the method Render, so i can use the ClientScriptManager to register the CrystalReportViewer's event, but how do i do it? I'm using the Crystal Report for VS.net 2005 Can anybody please help me?? thanks a lot  |

Is this a problem on your local machine or on a separate server? If it's on a separate web server, have you installed the latest version of the Crystal Merge Modules? You have to download it from the Business Objects website and install that version instead of the one that came with Visual Studion.

No , I'm still working at my local machine.I set the property <%@Page EnableEventValidation="false"%> and it worked.I thought it was a bigger problem because the exception showed was telling me to register my data event in the ClientScriptManger. But thanks a lot, i appriciated your support. Exception : Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. |
