Hotfix 5.1.16 problem

[dahami]

i've notice there are new version on this homepage.
my previous version is 4.8.14, so i've replace bunch of dlls.

The Problem is 'PdfGridCellContent' will cause unidentified problem.(or PdfGridCellContentList)
i don't know exact problem what it is.

but if i try old way(below code) on this version(5.1.16)
there are no problem.

Code: Select all

PdfGrid logogrid = new PdfGrid();
                                                            logogrid.Columns.Add(1);
                                                            PdfGridRow logorow = logogrid.Rows.Add();
                                                            logogrid.Columns[0].Width = tWidth;
                                                            logorow.Height = tHeight;
                                                            logorow.Cells[0].Style.BackgroundImage = logo_img;

i've used 'PdfGridCellContent' like this. there are fine on 4.8.14

Code: Select all

                                                            PdfGridCellContentList lst = new PdfGridCellContentList();
                                                            PdfGridCellContent textAndStyle = new PdfGridCellContent();
                                                            textAndStyle.Image = logo_img;
                                                            textAndStyle.ImageSize = new System.Drawing.SizeF(tWidth, tHeight);
                                                            lst.List.Add(textAndStyle);

                                                            cell.Value = lst;

Hi dahami,

Thanks for your inquiry.
Kindly note we have changed the class "PdfGridCellTextAndStyleList" and "PdfGridCellTextAndStyle" to "PdfGridCellContentList" and "PdfGridCellContent" from Spire.PDF version 4.5.8. With the latest version Spire.PDF Pack(Hot Fix) Version:5.1.16, I could use the class PdfGridCellContentList or PdfGridCellContent successfully and I didn't encounter any issue with your code. Please make sure you have updated the dlls correctly in your project. If there is still the issue, please provide more information, such as the the detailed error information, full code and the input files.

Sincerely,

using PdfGridCellContent with PdfStringFormat is cause 'NullReferenceException' on Grid.Draw(Page,Location)
previous version is no problem. in my case 4.8.14
this error is hard to find. and i really annoying because it's worked just fine before.
anyway i've to check my entire source code, because this is meaning it possible there are new problem on previous working code.
i'm pretty sure, if you have problem to seeing this error then you better check to dlls copied properly.

FYI
if you using PdfGridCellContent(List.Add(Image)) + PdfStringFormat then Error
PdfGridCellContent(List.Add(Text)/* Not setting Font and Brush */) + PdfStringFormat then Error.(but this case is Reasonable.)


PdfGridCellContent(List.Add(Text) /*setting Font and Brush */)
PdfGridCellContent(List.Add(Image)) + PdfStringFormat then Error. <------------ this is serious problem. i can understand above cases because they had logical problems.
but List.Add(Text with Font,Brush) and List.Add(Image) isn't have any logical problems i guess.

i hope you get point.

Hi,

Sorry for the inconvenience cuased.
Accroding to your information, I used following code to have a test. Unfortunatly, I still cannot reproduce your issue.

Code: Select all

PdfDocument doc = new PdfDocument();
PdfPageBase page = doc.Pages.Add();

PdfGrid grid = new PdfGrid();
grid.Columns.Add(1);
grid.Rows.Add();
grid.Style.CellPadding = new PdfPaddings(1, 1, 1, 1);
float width = page.Canvas.ClientSize.Width - (grid.Columns.Count + 1);
PdfGridRow row = grid.Rows.Add();
grid.Columns[0].Width = width * 0.25f;

PdfGridCellContentList lst = new PdfGridCellContentList();
PdfGridCellContent textAndStyle = new PdfGridCellContent();
textAndStyle.StringFormat = new PdfStringFormat() { Alignment = PdfTextAlignment.Center };
textAndStyle.Image = PdfImage.FromFile("logo.png");
textAndStyle.ImageSize = new SizeF(50, 50);
lst.List.Add(textAndStyle);
row.Cells[0].Value = lst;

PdfLayoutResult result = grid.Draw(page, new PointF(10, 30));
doc.SaveToFile(@"output.pdf", FileFormat.PDF);

To help us reproduce your issue quickly, please share your full code and the related file(input PDF, image file) if any.

your code works well.
i think problem is the way approching to set 'StringFormat'

in my case, i've set StringFormat on Cells generally like below article
