Answer 1

你先在报表中加入textobject 对象,然后通过reportDocument对象就可以访问了。
/// <summary>
/// 填充水晶报表数据
/// </summary>
public void FillPrintData(string reportPath)
{
if (this.Parameters.ContainsKey("YSZID"))
{
this.YSZID = this.Parameters["YSZID"].ToString();
                objPreSellLinence=new GESoft.FDJ.BusModules.wsba.Business.PreSellLinence(this.YSZID);
dtBody=objPreSellLinence.GetBuildingListOfLicence().Tables[0].Copy();
rdGrantCertificate.Load(reportPath);
//填充预售证表格信息
for(int row=0;row<dtBody.Rows.Count;row++)
{
for(int col =0;col<dtBody.Columns.Count;col++)
{
if(dtBody.Columns[col].ColumnName=="ZH")
{
string ctrName="to";
ctrName=ctrName+row.ToString()+"0";
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects[ctrName])).Text=dtBody.Rows[row][col].ToString(); 
}
if(dtBody.Columns[col].ColumnName=="DMCC")
{
string ctrName="to";
ctrName=ctrName+row.ToString()+"1";
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects[ctrName])).Text=dtBody.Rows[row][col].ToString(); 
}
if(dtBody.Columns[col].ColumnName=="FWYTMC")
{
string ctrName="to";
ctrName=ctrName+row.ToString()+"2";
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects[ctrName])).Text=dtBody.Rows[row][col].ToString(); 
}
if(dtBody.Columns[col].ColumnName=="ZJSMJ")
{
string ctrName="to";
ctrName=ctrName+row.ToString()+"3";
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects[ctrName])).Text=dtBody.Rows[row][col].ToString(); 
}
if(dtBody.Columns[col].ColumnName=="ZTS")
{
string ctrName="to";
ctrName=ctrName+row.ToString()+"4";
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects[ctrName])).Text=dtBody.Rows[row][col].ToString(); 
}

}
}
//填充预售证表头信息
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects["toCSellerName"])).Text=objPreSellLinence.DWMC;
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects["toCProjectName"])).Text=objPreSellLinence.XMMC;
GESoft.FDJ.BusModules.wsba.Business.Building objBuilding=new GESoft.FDJ.BusModules.wsba.Business.Building();
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects["toCLocation"])).Text=objBuilding.HouseSit(objPreSellLinence.LPZL);
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects["toCUserforlife"])).Text=objPreSellLinence.KSRQ.ToString()+"--"+objPreSellLinence.ZZRQ.ToString();
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects["toLinenceId"])).Text=objPreSellLinence.YSZH.ToString();
((TextObject)(rdGrantCertificate.ReportDefinition.Sections["Section3"].ReportObjects["toRe"])).Text=objPreSellLinence.BZ;
crvGrantCertificate.PrintMode=CrystalDecisions.Web.PrintMode.ActiveX;
crvGrantCertificate.ReportSource=rdGrantCertificate; }

Answer 2

建立水晶报表CR2,在CR2上放一个文本字段txtms.
其他的看下面的代码.
CR2 crt2=new CR2();TextObject getObjms;
getObjms=crt2.ReportDefinition.ReportObjects["txtms"] as TextObject;
getObjms.Text="区域销售汇总报表";
没问题吧!要看不懂我就没法了.

Answer 3

TextObject  需要引用什么？
