How to change alignment of a report field in cryst

问题:

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.

in C#:

var field = report.ReportDefinition.ReportObjects["Description1"];
field.ObjectFormat.HorizontalAlignment = Alignment.Justified;

possible choices:

namespace CrystalDecisions.Shared
{
    public enum Alignment
    {
        DefaultAlign,
        LeftAlign,
        HorizontalCenterAlign,
        RightAlign,
        Justified,
        Decimal,
    }
}

I used text interpretation = RTF Text and set value in rich text format and my problem is solved... I designed better crystal report dynamically using RTF.
