Steps to reproduce:
1. Load a PDF document with 0 pages
2. Enter some text in the search textbox and click the next/prev buttons
Expected: the search textbox should be either disabled or should ignore any search operation
Actual: an error occurs
Workaround:
Private Sub pdf_Viewer_DocumentLoaded(sender As Object, e As EventArgs)
If pdf_Viewer.Document.Pages.Count = 0 Then
pdf_Toolbar.SearchTextBox.Enabled = False
pdf_Toolbar.NextButton.Enabled = False
pdf_Toolbar.PreviousButton.Enabled = False
Else
pdf_Toolbar.SearchTextBox.Enabled = True
pdf_Toolbar.NextButton.Enabled = True
pdf_Toolbar.PreviousButton.Enabled = True
End If
End Sub
Use the attached pdf document and launch the PdfPrintPreviewDialog. As it is demonstrated in the gif file, the preview dialog moves the pages slower than the pdf viewer itself.
Expected behavior: the performance for navigating the pages should be at least identical.
This is the result with R3 2022:
This is the result with R2 2023 SP1:
Load a document with bookmarks and select the bookmarks options. Then, move the splitter:
Expected: the selected option (bookmarks) is unchanged
Actual: the selected option (bookmarks) is not preserved and it is reset
public TestRadForm()
{
InitializeComponent();
this.radPdfViewer1.LoadDocument(@"..\..\..\SampleDocument.pdf");
}
private void radButton1_Click(object sender, EventArgs e)
{
this.radPdfViewer1.Document.AcroForm.FlattenFormFields();
this.radPdfViewer1.SaveDocument(@"..\..\saved.pdf");
}
When importing a document containing a single associated widget annotation merged into the field dictionary the field is skipped on import and an exception is thrown.
According to the PDF Specification: Field Dictionaries: Kids:
An array of indirect references to the immediate children of this field.
In a non-terminal field, the Kids array is required to refer to field dictionaries that are immediate descendants of this field. In a terminal field, the Kids array ordinarily must refer to one or more separate widget annotations that are associated with this field. However, if there is only one associated widget annotation, and its contents have been merged into the field dictionary, Kids must be omitted.
The viewer is using a large amount of memory when scrolling a specific PDF file. After some point, an OutOfMemeory exception is thrown.
