如何在运行时更改Crystal报表中的报表字段的对齐方式 [英] How to change alignment of a report field in crystal reoport at runtime

问题描述

在水晶报表中，我想相应地设置字段的对齐方式。我如何在运行时也这样做？

---

这很好。这是工作。代码如下所示。

  var fo = rpt.ReportDefinition.ReportObjects [InvoiceComment]; 
 fo.ObjectFormat.Horizo​​ntalAlignment = Alignment.LeftAlign; 
 if（ds.Tables [0] .Rows [0] .ItemArray [19] .ToString（）==Right）
 fo.ObjectFormat.Horizo​​ntalAlignment = Alignment.RightAlign; 
 else 
 if（ds.Tables [0] .Rows [0] .ItemArray [19] .ToString（）==Center）
 fo.ObjectFormat.Horizo​​ntalAlignment = Alignment.Horizo​​ntalCenterAlign ;`
  

但我现在遇到另一个问题。

  FieldObject fo = rpt.ReportDefinition.ReportObjects [InvoiceComment] as FieldObject; 
  

或

  var fo = rpt.ReportDefinition.ReportObjects [InvCom]; 
  

显示相同的错误索引超出数组的边界。
如果我使用另一个代码，而不是它的工作原理。

  FieldObject fo = rpt.ReportDefinition.ReportObjects [35] 
  

如何进行此操作。

要更改字段的水平对齐，请按照以下步骤操作：

1）右键单击字段。

2）单击格式字段选项。

3）选择公共选项卡。

4）单击水平对齐前的公式编辑器，然后添加所需的设置。 >

5）以下是可用的对齐常量：

常量

  crDefaultHorAligned 
 
 crLeftAligned 
 
 crRightAligned 
 
 crCenteredHorizo​​ntally 
 
 crJustified 
  

按照您的标准使用它。

In a crystal report, I want to set alignment of a fields accordingly. How can i do the same at run time?

That's nice.This is working.Thanks.I did same, and code is shown below.

var fo = rpt.ReportDefinition.ReportObjects["InvoiceComment"];
fo.ObjectFormat.HorizontalAlignment = Alignment.LeftAlign;
if (ds.Tables[0].Rows[0].ItemArray[19].ToString() == "Right")
    fo.ObjectFormat.HorizontalAlignment = Alignment.RightAlign;
else
    if (ds.Tables[0].Rows[0].ItemArray[19].ToString() == "Center")
        fo.ObjectFormat.HorizontalAlignment  = Alignment.HorizontalCenterAlign;`  

But I'm going through another problem now.

FieldObject fo = rpt.ReportDefinition.ReportObjects["InvoiceComment"] as FieldObject;                       

OR

var fo = rpt.ReportDefinition.ReportObjects["InvCom"];

Are showing same error "Index was outside the bounds of the array." And if I use Another code instead of that it works.

FieldObject fo = rpt.ReportDefinition.ReportObjects[35] as FieldObject;                                                       

How to encurr this. Thanks in Advance.
