这是针对datagridview到crystal报表的。我还想将dtpFrom和dtpTo的datimepicker值显示给crystal Report。

首先通过 Crystal Reports - >在Crystal报表的某处添加文本对象 插入 - > 文字对象。文本对象的默认名称是 Text1 。您可以在文本对象属性下看到它。如果需要,您可以更改此名称。现在,在您的C#代码中,您需要传递Time的值。
示例:
ReportDocument rptDoc = new ReportDocument();
protected void Page_Init(object sender, EventArgs e)
{
// Load the report path
string reportPath = Server.MapPath("~/CrystalReportTime.rpt");
rptDoc.Load(reportPath);
CrystalReportViewer1.ReportSource = rptDoc;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string reportPath = Server.MapPath("~/CrystalReportTime.rpt");
rptDoc.Load(reportPath);
CrystalReportViewer1.ReportSource = rptDoc;
}
DataSet ds = new DataSet();
DataTable dt = new DataTable();
dt.Columns.Add("Name", typeof(String));
dt.Columns.Add("Class", typeof(String));
dt.Columns.Add("RollNo", typeof(String));
foreach (DataGridViewRow dgr in dgv_Student.Rows)
{
dt.Rows.Add(dgr.Cells["Name"].Value, dgr.Cells["Class"].Value, dgr.Cells["RollNo"].Value);
}
ds.Tables.Add(dt);
rptDoc.SetDataSource(ds);
// Pass the time to the Crystal Reports text object
CrystalDecisions.CrystalReports.Engine.TextObject Text1;
Text1 = rptDoc.ReportDefinition.ReportObjects["Text1"] as TextObject;
Text1.Text = "Time from " + String.Format("{0:MMMM dd, yyyy}", Convert.ToDateTime(dtpFrom)) + " to " + String.Format("{0:MMMM dd, yyyy}", Convert.ToDateTime(dtpTo));
}
protected void Page_UnLoad(object sender, EventArgs e)
{
this.CrystalReportViewer1.Dispose();
this.CrystalReportViewer1 = null;
rptDoc.Close();
rptDoc.Dispose();
rptDoc = null;
GC.Collect();
}
希望这有帮助。
