Hi all,
User views a Crystal report. He wants to open a particular translation form for correction at the same time. How can he do it?
please suggest me ,how can i implement this issue. Looks like a hyperlink that opens winform.

答

我从没想过要这样做，但是我确实有一些托管CrystalReportViewer控件的表单，认为可以做到的.

该控件引发一个事件ClickPage，该事件具有一个CrystalDecisions.Windows.Forms.PageMouseEventArgs参数.它具有属性ObjectInfo，该属性包含有关所选对象"(大概是用户单击的对象)的信息.如果用户单击链接，则应该可以将其转换并提取有意义的信息.然后，您可以使用此信息来打开翻译表单X.

我没有使用报表中嵌入的链接，所以我可能是错的.仍然....尝试在链接的URL字段中对您的信息进行编码.创建一个伪协议，然后创建一个字段，指出要打开的表单，例如trans:SPA.当ClickPage截获点击时，如果对象是链接，并且链接具有以trans:开头的URL，则可以打开请求的翻译表单.否则，将其视为普通URL.

让我知道这是否可行，我可以看到一些很好的用法.

I''ve never thought to do this, but I do have some forms that host the CrystalReportViewer control and I think it can be done.

The control raises an event, ClickPage, which has a CrystalDecisions.Windows.Forms.PageMouseEventArgs parameter. This has a property, ObjectInfo, which carries information about "the selected object," presumably, the object that the user clicked. If the user clicked on a link, it should be possible to convert it and extract meaningful information. You can then use this information to open translation form X.

I have not used links embedded in reports, so I may be wrong. Still.... Try encoding your information in the link''s URL field. Create a pseudo protocol, and then a field indicating the form to open, say, trans:SPA. When ClickPage intercepts the click, if the object is a link and the link has a URL that starts with trans: you can open the requested translation form. Otherwise, treat it as a normal URL.

Let me know if this works, I can see a few nice uses for this.

我知道这有点晚了，但是你不敢相信我花了多长时间寻找对于这种解决方案，其他大多数相关文章都提到它不可能"，因此非常感谢Gregory张贴此文章.

通过添加以下代码，它与我完美协作:

I know it''s a little bit late, but you can''t believe how long I spent looking for such a solution, most of the other related posts mentioned that it''s "NOT POSSIBLE", so thanks a lot Gregory for posting this.

It worked perfectly with me, by adding the following code:

Private Sub CRV_ClickPage(ByVal sender As System.Object, ByVal e As CrystalDecisions.Windows.Forms.PageMouseEventArgs) Handles CRV.ClickPage
        If e.ObjectInfo.Name = "vouCode" Then
            Dim frmToLoad As New Services
            frmToLoad.LoadOrders(e.ObjectInfo.Text)
            frmToLoad.Show()
        End If
    End Sub

e.ObjectInfo.Name将返回IFieldObject名称，而e.ObjectInfo.Text将返回其文本.

Where e.ObjectInfo.Name will return the IFieldObject name, and e.ObjectInfo.Text will return it''s text.
