问题描述

我的代码是......

DataSet ds = new DataSet（）;

ds = cn.ExecuteDataset（str）;

ReportDocument rd = new ReportDocument（）;

TableLogOnInfos crtableLogoninfos = new TableLogOnInfos（）;

//传递参数值************************** ************

会话[dt1] = txtfrmDt.Text.ToString（）;

会话[dt2] = txttoDt.Text.ToString（）;



string dtrpt = txtfrmDt.Text.ToString（）;

string dtrpt1 = txttoDt.Text。 ToString（）;





//创建参数对象

ParameterFields myParams = new P arameterFields（）;

ParameterField myParam = new ParameterField（）;

ParameterField myParam1 = new ParameterField（）;

ParameterField myParamprd = new ParameterField（ ）; $



ParameterDiscreteValue myDiscreteValue = new ParameterDiscreteValue（）;

ParameterDiscreteValue myDiscreteValue1 = new ParameterDiscreteValue（）;

ParameterDiscreteValue myDiscreteValueprd = new ParameterDiscreteValue（）;





//将ParameterFieldName设置为参数名称

//在Field Explorer中创建

myParam.ParameterFieldName =dtfrm;

myParam1.ParameterFieldName =dtto;

myParamprd。 ParameterFieldName =prd;



//添加值

myDiscreteValue.Value = Session [dt1]。ToString（）; / / dtrpt;

myDisc reteValue1.Value = Session [dt2]。ToString（）; // dtrpt1;

myDiscreteValueprd.Value = ddProdID.SelectedItem.Text.ToString（）;



myParam.CurrentValues.Add（myDiscreteValue）;

myParam1.CurrentValues.Add（myDiscreteValue1）;

myParamprd.CurrentValues.Add（myDiscreteValueprd）;



//将pararam对象添加到params集合

myParams.Add（myParam）;

myParams.Add （myParam1）;

myParams.Add（myParamprd）;



//将params集合分配给报表查看器

推荐答案

你应该使用事件来实现代码..



尝试使用回发检查将DataBindings放在PageLoad上并进行检查。



-Thanks。

YOu should specify code with events..

Try to put DataBindings on PageLoad with postback checking and check it.

-Thanks.
