AR3 中页面特定的边距设置

发布于 2024-09-11 17:06:35 字数 996 浏览 4 评论 0原文

我正在尝试根据页码以编程方式设置活动报表中的边距。

具体来说，第一页需要有较小的边距（以便最上面带有寄信人地址的文本框与公司徽标的对齐方式相匹配），之后的每一页都应具有标准的 2.54 厘米边距。

我读过的帖子表明检测实际页码可能会出现问题，因此我尝试使用 ReportStart 和 PageStart 处理程序以及一些非常简单的逻辑来设置边距。

在报告的代码隐藏中，我添加了两个处理程序和布尔值：

 this.ReportStart += UFAnReportStart;
        this.PageStart += UFAnPageStart;
 bool bFirstPage = true;

然后添加了两个回调，如下所示：

private void UFAnReportStart(object sender, System.EventArgs eArgs)
    {           
        this.PageSettings.Margins.Top = 0.1965278F;
    }

private void UFAnPageStart(object sender, System.EventArgs eArgs)
    {
        // every page after the first should have standard margins.
        if (!bFirstPage)
        {               
            this.PageSettings.Margins.Top = 2.54F;
        }
        bFirstPage = false;
    }

这似乎对边距没有任何影响。这种方法完全是错误的吗？或者 PageSettings 对象是报表范围的属性吗？

欢迎任何关于替代方法的建议。

谢谢你！

I'm trying to programmatically set the margins in an active report based on the page number.

Specifically, the first page needs to have small margins (so that the top-most text box with a return address matches the alignment of a company logo) and every page after that should have standard 2.54cm margins.

I've read posts that suggest that detecting the actual page number can be problematic so I've tried using the ReportStart and PageStart handlers along with some very simple logic to set the margins.

In the code-behind for the report, I added the two handlers and bool value:

 this.ReportStart += UFAnReportStart;
        this.PageStart += UFAnPageStart;
 bool bFirstPage = true;

And then added the two callbacks as follows:

private void UFAnReportStart(object sender, System.EventArgs eArgs)
    {           
        this.PageSettings.Margins.Top = 0.1965278F;
    }

private void UFAnPageStart(object sender, System.EventArgs eArgs)
    {
        // every page after the first should have standard margins.
        if (!bFirstPage)
        {               
            this.PageSettings.Margins.Top = 2.54F;
        }
        bFirstPage = false;
    }

This doesn't seem to have any effect on the margins. Is this approach just plain wrong? Or is the PageSettings object a report wide property?

Any suggestions for alternative approaches are welcomed.

Thank you!

以编程方式，单位为英寸而不是 CM :) 设计时设置仅影响设计器中显示的内容。

以下内容对我有用：

public void ActiveReport_ReportStart()
{
    rpt.PageSettings.Margins.Top = 0.05f;
    rpt.PageSettings.Margins.Left = 0.05f;
    rpt.PageSettings.Margins.Right = 0.05f;
    rpt.PageSettings.Margins.Bottom = 0.05f;    
}

public void ActiveReport_PageEnd()
{
    // The first page (page index 0) will inherit the page margins set in ReportStart. 
    // We immediately reset the page margins in the first PageEnd event to ensure subsequent pages get the larger margins.
    if (rpt.Document.Pages.Count == 0)
    {
        rpt.PageSettings.Margins.Top = 1.0f;
        rpt.PageSettings.Margins.Left = 1.0f;
        rpt.PageSettings.Margins.Right = 1.0f;
        rpt.PageSettings.Margins.Bottom = 1.0f;
    }
}

Programmatically the units are in inches not CM :) The design-time setting only affects what is shown in the designer.

The following worked for me:

public void ActiveReport_ReportStart()
{
    rpt.PageSettings.Margins.Top = 0.05f;
    rpt.PageSettings.Margins.Left = 0.05f;
    rpt.PageSettings.Margins.Right = 0.05f;
    rpt.PageSettings.Margins.Bottom = 0.05f;    
}

public void ActiveReport_PageEnd()
{
    // The first page (page index 0) will inherit the page margins set in ReportStart. 
    // We immediately reset the page margins in the first PageEnd event to ensure subsequent pages get the larger margins.
    if (rpt.Document.Pages.Count == 0)
    {
        rpt.PageSettings.Margins.Top = 1.0f;
        rpt.PageSettings.Margins.Left = 1.0f;
        rpt.PageSettings.Margins.Right = 1.0f;
        rpt.PageSettings.Margins.Bottom = 1.0f;
    }
}
