Majorsilence Reporting 26.0.8

Majorsilence Reporting 26.0.8 is a patch for the 26.0 line. A bordered rectangle now grows with the subreport inside it, the embedded designer stops stalling in hosts like WPF, and three runtime packages move past known vulnerabilities. One viewer change needs a line of code in some apps.

Here's a bordered rectangle around a subreport that grows. In 26.0.7 the border drew as a thin strip at the top, and the item below it printed over the subreport. Now the rectangle stretches to the subreport's last item, the way SSRS does. The border and background follow it down, and the item below keeps its gap. A rectangle whose contents fit keeps its height.

If you embed the designer control in your own app, this one looked like a hang. On the Design tab, GetRdlText read a setting that only the stand-alone designer has. The exception showed a message box with no owner window, which a WPF host can hide, and then returned an empty string. The read is now null-safe, and the message box belongs to the control.

NewLineChars = RdlDesigner?.XmlNewLine == NewLineChar.Unix ? "\n" : "\r\n",
MessageBox.Show(this, ex.Message, Strings.DesignCtl_Show_UnableCreateRDL);

The preview viewer only received the report when someone opened the Preview tab. So an app that called OpenFile and then exported or printed straight away used the old report. Print and SaveAs now hand the preview the current report first, edits included, so you export the report you opened.

designer.OpenFile(path);
await designer.SaveAsAsync("out.pdf",
    OutputPresentationType.PDF);

Loading a second report used to leave the editor marked as modified, with the previous report still on its undo stack. Now every load resets both. There's also a new RdlChanged event on the designer control. It fires when the user edits the report and stays quiet on a load, so your app can track unsaved changes.

designer.RdlChanged += (s, e) =>
    UpdateTitle(designer.Modified);

This release also updates packages with known vulnerabilities. Microsoft's SQLite package moves from 8.0.4 to 8.0.32, and the two cryptography packages, for PKCS and for XML, each move up one patch release. Testcontainers moves too, but only the test projects use it.

This is the one change that can break existing code. PageCount, PageHeight and four other viewer properties used to force the report to load. They blocked while it rendered on a pool thread, and that could hang the app. Now they return zero or the default until the report renders. If you read them, await EnsureRendered on the viewer first. The viewer's own print button already does.

int pages = viewer.PageCount;
// rendered on a pool thread first

await viewer.EnsureRendered();
int pages = viewer.PageCount;

To upgrade, move your Majorsilence Reporting packages to 26.0.8. First, check any code that reads PageCount or the other viewer properties before the report renders. It needs an await on EnsureRendered. And if you load rdlnative from another language, it now finds the HarfBuzz library in its own folder, the same way it finds SkiaSharp. That's 26.0.8: rectangles that grow with their subreports, and an embedded designer that stops stalling.
