如何在运行时更改水晶报表中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.我怎样才能在运行时做同样的事情?

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

很好.这正在工作.谢谢.我也做了，代码如下所示.

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;`  

但是我现在遇到了另一个问题.

But I'm going through another problem now.

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了数组的范围."如果我使用另一个代码而不是它，它会起作用.

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;                                                       

如何发生这种情况.提前致谢.

How to encurr this. Thanks in Advance.
