动态地将报告源提供给reportviewer [英] dynamically giving report source to reportviewer

问题描述

嗨 我如何动态地将报告源提供给单个报告查看器?...即，如果选择了a复选框，则在reportviewer中显示a的报告；如果选择了b，则在同一reportviewer中显示b的报告
谢谢你

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(" )；
        CRPTViewer.ReportSource = rpt;
        CRPTViewer.RefreshReport();
    }
    如果(B.Checked == 真)
    {
        ReportDocument rpt = 新 ReportDocument();
        rpt.Load(" )；
        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(" )；
    }
    其他
    {
        rpt.Load(" )；
    }
    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
