使用datetimepicker过滤水晶报告中的数据 [英] Filter data in crystal report using datetimepicker
问题描述
我正在处理一个报表在水晶报表C＃Windows应用程序。从本地主机服务器获取数据水晶报表。我的表单中有2个datetimepicker。
datetimepicker1 = dtpfrom
datetimepicker2 - dtpto
Crystalreport
现在我想要的是，当选择一些日期时，从datetimepicker中，数据之间显示水晶报告请帮我解决我不知道怎么开始。我搜索通过googling我没有得到任何关于datetimepicker中的数据之间显示在水晶报告。任何想法？
这里我尝试：
MySqlConnection conn = new MySqlConnection（MyCon）;
CrystalReport1 objcr = new CrystalReport1（）;
MySqlDataAdapter da = new MySqlDataAdapter（select * from data where date> ='+ DateTime.Parse（dtpfrom.Text）+'and date< ='+ DateTime.Parse（dtpto.Text）+ '，conn）;
DataTable dt = new DataTable（）;
da.Fill（dt）;
objcr.SetDataSource（dt）;
crystalReportViewer1.ReportSource = objcr;
crystalReportViewer1.RefreshReport（）;
但我收到了错误
< >
未处理的类型为
的异常'CrystalDecisions.CrystalReports.Engine.DataSourceException'出现
在CrystalDecisions.ReportAppServer.DataSetConversion.dll中
其他信息：无法加载数据库信息。
在线：

objcr.SetDataSource（dt）;

使用datetimepicker筛选报告中的数据未针对您的编码进行
执行以下操作：
$ b
在字段资源管理器中创建一个新的参数fromdate，todate - >参数字段（右键） - >新建
像这样make todate也
然后右键单击报告。
选择报告 - >选择公式 - >记录...
执行以下操作
：
右键点击报告 - >数据库 - >设置数据源位置...
现在代码
ReportDocument report = new ReportDocument
report.Load（C：\\Users\\Desktop\\CrystalReport1.rpt）;
TableLogOnInfo Table = new TableLogOnInfo（）;
ConnectionInfo Connection = new ConnectionInfo（）;
表表;
ParameterFieldDefinitions参数;
ParameterFieldDefinition参数;
ParameterValues Values = new ParameterValues（）;
ParameterDiscreteValue DiscreteValue = new ParameterDiscreteValue（）;
DiscreteValue.Value = dateTimePicker1.Text;
Parameters = report.DataDefinition.ParameterFields;
Parameter = Parameters [fromdate];
Values = Parameter.CurrentValues;
Values.Clear（）;
Values.Add（DiscreteValue）;
Parameter.ApplyCurrentValues（Values）;
DiscreteValue.Value = dateTimePicker2.Text;
Parameters = report.DataDefinition.ParameterFields;
Parameter = Parameters [todate];
Values = Parameter.CurrentValues;
Values.Add（DiscreteValue）;
Parameter.ApplyCurrentValues（Values）;
Connection.ServerName =您的服务器名称在设置数据源位置;
Connection.DatabaseName =您的数据库名称在设置数据源位置;
Connection.UserID =您的用户名;
Connection.Password =your password;
Tables = report.Database.Tables;
foreach（表中的CrystalDecisions.CrystalReports.Engine.Table表）
{
Table = table.LogOnInfo;
Table.ConnectionInfo = Connection;
table.ApplyLogOnInfo（Table）;
}
crystalReportViewer1.ReportSource = report;
crystalReportViewer1.Refresh（）;
希望这有助于解决您的问题。
I'm working on a report in Crystal Reports C# windows application.i fetch the data from localhost server to crystal report. I have 2 datetimepicker in my form.
datetimepicker1 = dtpfrom

Here my try:
MySqlConnection conn = new MySqlConnection(MyCon);
CrystalReport1 objcr = new CrystalReport1();
MySqlDataAdapter da = new MySqlDataAdapter("select * from data where date>='" + DateTime.Parse(dtpfrom.Text) + "' and date<='" + DateTime.Parse(dtpto.Text) + "' ", conn);
DataTable dt = new DataTable();
da.Fill(dt);
objcr.SetDataSource(dt);
crystalReportViewer1.ReportSource = objcr;
crystalReportViewer1.RefreshReport();
But i'm getting an error
An unhandled exception of type 'CrystalDecisions.CrystalReports.Engine.DataSourceException' occurred in CrystalDecisions.ReportAppServer.DataSetConversion.dll
Additional information: Failed to load database information.

@divi
filter data in report using datetimepicker is not done for your coding
Do the following:
create a new parameter fromdate, todate in Field Explorer -> Parameter Field(Right Click)-> New
like this make todate also
then right click the report.
Select Report -> Selection Formula -> Record...
Do following
then click save and close button in that form.
Know this:
Right Click the report -> Database -> Set Datasource Location...
Now Code
ReportDocument report = new ReportDocument();
report.Load("C:\\Users\\Desktop\\CrystalReport1.rpt");
TableLogOnInfo Table = new TableLogOnInfo();
ConnectionInfo Connection = new ConnectionInfo();
Tables Tables;
ParameterFieldDefinitions Parameters;
ParameterFieldDefinition Parameter;
ParameterValues Values = new ParameterValues();
ParameterDiscreteValue DiscreteValue = new ParameterDiscreteValue();
DiscreteValue.Value = dateTimePicker1.Text;
Parameters = report.DataDefinition.ParameterFields;
Parameter = Parameters["fromdate"];
Values = Parameter.CurrentValues;
Values.Clear();
Values.Add(DiscreteValue);
Parameter.ApplyCurrentValues(Values);
DiscreteValue.Value = dateTimePicker2.Text;
Parameters = report.DataDefinition.ParameterFields;
Parameter = Parameters["todate"];
Values = Parameter.CurrentValues;
Values.Add(DiscreteValue);
Parameter.ApplyCurrentValues(Values);
Connection.ServerName = "Your servername in Set Datasource Location";
Connection.DatabaseName = "Your databasename in Set Datasource Location";
Connection.UserID = "your username";
Connection.Password = "your password";
Tables = report.Database.Tables;
foreach (CrystalDecisions.CrystalReports.Engine.Table table in Tables)
{
Table = table.LogOnInfo;
Table.ConnectionInfo = Connection;
table.ApplyLogOnInfo(Table);
}
crystalReportViewer1.ReportSource = report;
crystalReportViewer1.Refresh();
Hope This helps to solve your problem.
