Crystal Reports不断提示输入参数 [英] Crystal Reports keeps prompting for Parameter

问题描述

我有一个可怕的问题，水晶报告2010年的.net 4.0（我使用固定的13.0.1版本，但13.0.4发布）。无论以哪种方式尝试，我总是得到一个提示对话框，以第一次输入我的一个参数值。

I am having a terrible problem with crystal report 2010 for .net 4.0 (I am using the fixed 13.0.1 version but 13.0.4 is released). No matter which way I try, I am always getting a prompting dialogue box to input my one parameter value the first time.

CrystalReportViewer1.ReportSource = CustomerReport1;    
CustomerReport1.Database.Tables[0].SetDatasource ( this.dataset);        
CustomerReport1.SetParameterValue("PathLocation", Location.Text);

CustomerReport1.Parameter_PathLocation.CurrentValues.Add(Location.Text) // to be safe using CS 2010 for .net 4
CrystalReportViewer1.ReuseReportParametersOnRefresh = true; // to prevent from showing again and again.

我也尝试过：

CustomerReport1.Database.Tables[0].SetDatasource ( this.dataset);        
CustomerReport1.SetParameterValue("PathLocation", Location.Text);

CrystalReportViewer1.ReportSource = CustomerReport1;

并且：

CustomerReport1.Database.Tables[0].SetDatasource ( this.dataset);        
CustomerReport1.Parameter_PathLocation.CurrentValues.Add(Location.Text)

CrystalReportViewer1.ReportSource = CustomerReport1; // the parameter in the report has Optional Parameter = false, Static , Multiple Value = false .

任何人都可以帮忙吗？我对此感到沮丧。它在以前的版本中工作，但现在我得到这个提示框。

Can anyone please help? I am getting frustrated with this. It worked in previous versions, but now I am getting this prompt box.

谢谢。

推荐答案

终于找到了解决方案。如果我们在 ParameterValue 之后设置 DataSource ，则不会提示。

Finally found the solution. It doesn't prompt if we set the DataSource after the ParameterValue.

所以任何人都会工作，如果我们按顺序：

So anyone of those will work if we put them in this order:

// First, call SetParameterValue. Then, call SetDatasource.     
CustomerReport1.SetParameterValue("PathLocation", Location.Text);
CustomerReport1.Database.Tables[0].SetDatasource(this.dataset);

CrystalReportViewer1.ReportSource = CustomerReport1;

谢谢大家。
