    如何使用代码动态设置水晶报表中的文本,字段等对象呢?

    //VB

    首先,你必须要声明一个OBJECT变量(eg. TextObject, FieldObject, ......),当然不是一般的对象,而是:
       Dim xObject As CrystalDecisions.CrystalReports.Engine.FieldObject(字段)
       Dim xObject As CrystalDecisions.CrystalReports.Engine.TextObject(文本)
      Dim xObject As CrystalDecisions.CrystalReports.Engine.LineObject(线条)
       Dim xObject As CrystalDecisions.CrystalReports.Engine.BoxObject(矩形框)
    ......
    其次,你必须将水晶报表的真实对象赋值给它,例如:
       xObject = crReport.ReportDefinition.ReportObjects.Item("FieldObjectName")
       xObject = crReport.ReportDefinition.ReportObjects.Item("TextObjectName")
       xObject = crReport.ReportDefinition.ReportObjects.Item("LineObjectName")
       xObject = crReport.ReportDefinition.ReportObjects.Item("BoxObjectName")
    ......
    然后,你就可以调用它的各种属性和方法了:

     对于FieldObject,你可以:
       1.设置数值字段的小数点位数:
             xObject.FieldFormat.NumericFormat.DecimalPlaces = 4
          2.设置布尔字段的输出类型: 
            xObject.FieldFormat.BooleanFormat.OutputType =CrystalDecisions.Shared.BooleanOutputType.YesOrNo
          3.设置其他格式如(CommonFormat,DateTimeFormat,DateFormat,TimeFormat)

     对于TextObject,你可以:
        1.改变文本:
               xObject.Text = "嘿嘿"
            2.改变字体: 
              xObject.ApplyFont(New Font("宋体", 10.0!))
            3.设置颜色:
         xObject.Color = Color.Red
        3.隐藏显示:
         xObject.ObjectFormat.EnableSuppress = True

     对于LineObject,你可以:
        1.设置线条风格:
              xObject.LineStyle = CrystalDecisions.Shared.LineStyle.DotLine
            2.设置线条颜色: 
              xObject.LineColor = Color.Blue
            3.设置线条宽度:
         xObject.LineThickness = 3
            4.设置其他格式(如:位置(top,left,right,bottom),边框等)
         
     对于BoxObject,你可以:
        1.设置填充颜色:
              xObject.FillColor = Color.Brown
        2.设置线条风格:
              xObject.LineStyle = CrystalDecisions.Shared.LineStyle.DotLine
            3.设置线条颜色: 
              xObject.LineColor = Color.Blue
            4.设置线条宽度:
         xObject.LineThickness = 3
            5.设置其他格式(如:位置(top,left,right,bottom),边框等)

     

    //C#
        
       CrystalDecisions.CrystalReports.Engine.TextObject xObject;
       xObject = (CrystalDecisions.CrystalReports.Engine.TextObject)CrystalReportSource1.ReportDocument.ReportDefinition.ReportObjects["Text1"];   
       xObject.Text="条件";
