在生成水晶报表时加载 [英] Loading while crystal report generates

问题描述

我正在从Crystal报表中获取数据以生成报表查看器.显示报告需要时间.
我想在加载数据时显示一个等待光标.我试图覆盖IsLoad()方法.我没有实现它.如果有人知道，请帮助我.

I am fetching data from crystal report to report viewer. It takes time to show the report.
I want to show a wait cursor while loading data. I am trying to override IsLoad() method. I fail to implement it. If any one knows, then kindly help me.

if (cmb_Status.Text == "Occupied")
           {
               OleDbDataAdapter adapter = new OleDbDataAdapter("select * from tbl_Bed where Status='Occupied'", con);
               DataSet dss = new DataSet();
               adapter.Fill(dss, "tbl_Bed");
               if (dss.Tables["tbl_Bed"].Rows.Count > 0)
               {
                   JeevanDeep.Report.ReportBedStatus bed = new JeevanDeep.Report.ReportBedStatus();
                   bed.SetDataSource(dss);
                   crystalReportViewer1.ReportSource = bed;
                   crystalReportViewer1.Zoom(50);

               }
           }

谢谢和问候，

推荐答案

使用Cursor属性.仅此而已.

Use the Cursor property. that''s all.

if (cmb_Status.Text == "Occupied")
{
OleDbDataAdapter adapter = new OleDbDataAdapter("select * from tbl_Bed where Status='Occupied'", con);
DataSet dss = new DataSet();
adapter.Fill(dss, "tbl_Bed");
if (dss.Tables["tbl_Bed"].Rows.Count > 0)
{
this.Cursor = Cursors.WaitCursor;//Wait Cursor
JeevanDeep.Report.ReportBedStatus bed = new JeevanDeep.Report.ReportBedStatus();
bed.SetDataSource(dss);
crystalReportViewer1.ReportSource = bed;
crystalReportViewer1.Zoom(50);
this.Cursor = Cursors.Default;//Default Cursor
}
}

if (cmb_Status.Text == "Occupied")
{
     Cursor = Cursors.WaitCursor;
     
OleDbDataAdapter adapter = new OleDbDataAdapter("select * from tbl_Bed where Status=''Occupied''", con);
DataSet dss = new DataSet();
adapter.Fill(dss, "tbl_Bed");
if (dss.Tables["tbl_Bed"].Rows.Count > 0)
{
JeevanDeep.Report.ReportBedStatus bed = new JeevanDeep.Report.ReportBedStatus();
bed.SetDataSource(dss);
crystalReportViewer1.ReportSource = bed;
crystalReportViewer1.Zoom(50);

}
Cursor = Cursors.Default;
}
