推荐答案

私有无效Page_Load(object sender，System.EventArgs e)
{
CrystalReportViewer1.DataBind();
SetParameterFields();
}

受保护的void SetParameterFields()
{
ParameterField f1 = CrystalReportViewer1.ParameterFieldInfo [0];
ParameterDiscreteValue v1 =新的ParameterDiscreteValue();
v1.Value = Request.QueryString ["Whatever"]; //或Session("Whatever")
f1.CurrentValues.Add(v1);
CrystalReportViewer1.RefreshReport();
}

private void Page_Load(object sender, System.EventArgs e)
{
CrystalReportViewer1.DataBind();
SetParameterFields();
}

protected void SetParameterFields ()
{
ParameterField f1 = CrystalReportViewer1.ParameterFieldInfo[0];
ParameterDiscreteValue v1 = new ParameterDiscreteValue();
v1.Value = Request.QueryString["Whatever"]; //Or Session("Whatever")
f1.CurrentValues.Add(v1);
CrystalReportViewer1.RefreshReport();
}
