Hey guys
I am very new to asp.net and using Crystal Reports 8 with C#. When i fire a report everything seems to be working fine. But when the refresh button or the next page navigate button is pressed,I land up with an error "Object reference not set to an instance of an object."
Am i supposed to handle the refresh event? If so plz provide me some help

Thanx in advance

推荐答案

在init ........页中调用报告.

您还可以在crystalreport查看器的page_navigate事件中调用报告

call the report in page init.................


u can also call the report in page_navigate event of crystalreport viewer

如果有任何回发语句，请删除该内容

If there is any postback statement remove that one

您的报告是否包含一些参数字段???

does your report contains some parameter fields ???
