使用HyperLink将RDLC渲染为PDF [英] Render RDLC as a PDF, with a HyperLink

问题描述

我需要将超链接添加到PDF报告(RDLC). 在添加HyperLink(使用参数和数据集通过.NET生成的HyperLink)之前，该报表可以很好地呈现.

I have a requirement to add a Hyperlink to a PDF report (RDLC). The report renders fine before adding the HyperLink (generated via .NET, using parameters and datasets).

为了在代码中进行概念验证"，我添加了

To make a 'proof of concept' in code I have added

ReportViewer1.LocalReport.EnableHyperlinks = True
ReportViewer1.HyperlinkTarget = "_Blank"

在RDLC中，我添加了一个文本框，添加了一个转到URL"操作，并将URL设置为" http: //www.google.com '

In the RDLC I have added a TextBox, added an Action 'Go to URL' and set the URL as 'http://www.google.com'

渲染时我得到

处理本地报告时发生错误

An error occurred during local report processing

然后我更深入地研究错误时，innerException是

When I then have a look into the error in more depth, the innerException is

尚未指定运行报告所需的一个或多个参数.

One or more parameters required to run the report have not been specified.

我想念什么?

推荐答案

好的，不是很理想，但是我最终以XML而不是通过VisualStudio UI来编辑RDLC并使其正常工作.

Okay, not ideal, but I ended up editing the RDLC in XML, not via the VisualStudio UI and got it working.

然后我将硬编码的URL交换为参数

I've then swapped the hardcoded URL, to a Parameter

VS一定不能设置必需的东西.我在段落"之后添加了以下内容到对象XML的根中.

VS must not be setting something required. I added the following to the Root of the Object's XML, just after 'Paragraphs'.

</Paragraphs>
<ActionInfo>
    <Actions>
        <Action>    
            <Hyperlink>=Parameters!HyperlinkURL.Value</Hyperlink>
        </Action>
    </Actions>
</ActionInfo>

然后，将参数添加到"ReportParameters"下

And then, the Parameter added under 'ReportParameters'

<ReportParameters>
    <ReportParameter Name="HyperlinkURL">
        <DataType>String</DataType>
        <Nullable>true</Nullable>
        <AllowBlank>true</AllowBlank>
        <Prompt>HyperlinkURL</Prompt>
    </ReportParameter>
