解决方案

另外，您需要在show report button click事件中添加这样的代码....

受保护的 void btnShowReport_Click(对象发​​件人，EventArgs e) { 如果(A.Checked == true ) { ReportDocument rpt = 新 ReportDocument(); rpt.Load(" CrystalReport1.rpt" )； CRPTViewer.ReportSource = rpt; CRPTViewer.RefreshReport(); } 如果(B.Checked == 真) { ReportDocument rpt = 新 ReportDocument(); rpt.Load(" CrystalReport2.rpt" )； CRPTViewer.ReportSource = rpt; CRPTViewer.RefreshReport(); } }

使用此方法:

受保护的 无效 btnShowReport_Click(对象发​​件人，EventArgs e) { ReportDocument rpt = 新 ReportDocument(); 如果(A.Checked == true ) { rpt.Load(" CrystalReport1.rpt" )； } 其他 { rpt.Load(" CrystalReport2.rpt" )； } CRPTViewer.ReportSource = rpt; CRPTViewer.RefreshReport(); }

它将节省您的时间并提高速度 -谢谢.

解决方案

Fro this you need to put a code in show report button click event like this....

protected void btnShowReport_Click(object sender, EventArgs e) { if (A.Checked == true) { ReportDocument rpt = new ReportDocument(); rpt.Load("CrystalReport1.rpt"); CRPTViewer.ReportSource = rpt; CRPTViewer.RefreshReport(); } if (B.Checked == true) { ReportDocument rpt = new ReportDocument(); rpt.Load("CrystalReport2.rpt"); CRPTViewer.ReportSource = rpt; CRPTViewer.RefreshReport(); } }

Use this :

protected void btnShowReport_Click(object sender, EventArgs e) { ReportDocument rpt = new ReportDocument(); if (A.Checked == true) { rpt.Load("CrystalReport1.rpt"); } else { rpt.Load("CrystalReport2.rpt"); } CRPTViewer.ReportSource = rpt; CRPTViewer.RefreshReport(); }

It will save your time and gives speed -Thanks.
