Customizing Preview/Viewer

[Vital]

Sorry, we don't find any difference between your code and our code in default event handler. We use following method:

Code: Select all

protected void SendEMail(string subject, string body, string filePath)
{
       try
       {
		MAPI.SendEMail(subject, body, filePath);
	}
	catch (Exception e)
	{
		StiLogService.Write(this.GetType(), "Send E-mail");
		StiLogService.Write(this.GetType(), e);

		if (!StiReport.HideMessages)MessageBox.Show(e.Message);
	}
}

I have only one recommendation, try to use our code directly. You can find full version of MAPI class above:

Code: Select all

            message.subject = subject;
            message.noteText = body;
            message.fileCount = 1;
            message.files = GetFileDesc(filePath);
            return message;
        }

                Marshal.FreeHGlobal(msg.files);
                msg = null;
            }

        }

Does anyone else have this particular problem? I'm asking for a feature request for bookmarks. When the report shows, the bookmarkpanel on the left has to be hidden from the user. He / she can activate it by pressing the bookmarkbutton of the previewcontrol.

In that case the code should be a bit different:

Code: Select all

using (Stimulsoft.Report.Render.StiPreviewForm previewForm = new Stimulsoft.Report.Render.StiPreviewForm(report))
{
    report.PreviewControl = previewForm.PreviewControl;
    report.Render();
    previewForm.PreviewControl.BookmarksTreeView.Visible = false;
    (previewForm.PreviewControl.ToolBar.Controls["tbBookmarks"] as StiToolButton).Pushed = false;
    previewForm.ShowDialog();
}

This code hides the bookmarkpanel when the report is showed to the user, but "Bookmark" button remains visible, so the user may hide/show the bookmarks later if needed.

Thank you.

The code above seems to work. Thanks for your help. I noticed a little bug in the PreviewControl. When a report is shown, one can change the way the report is displayed with 3 little buttons in the bottom of the PreviewControl: SinglePage, Continuous, MultiplePages. When one of these buttons are pressed the bookmarkpanel is also automatically shown to the user. This is a strange behaviour of the PreviewControl and something a user doesn't want in my opinion.

Fixed. Patch will be available in build from 13 August.

Thank you.
