Hi Rajkumar,

We investigated the issue in the .NET Framework platform and successfully identified and resolved it. Since you initially mentioned WPF in the forum, we ensured the fix is included for .NET Framework as well. This fix will be part of the upcoming weekly release on 11/03/2025.

If you require a separate patch for .NET Framework before the official release, please let us know, and we will proceed accordingly.

 

Based on your forum response (link to forum post), we understand that you are working with .NET Core. Upon testing, we were able to reproduce the issue where "some text appears hidden behind the background color of the table."

 

• In .NET Framework, we process HTML elements using rich text and render them as a metafile, allowing background information to be applied correctly.
• However, in .NET Core, due to platform limitations, we cannot render text as a metafile. Instead, we handle rendering manually, leading to this issue.

 

Due to the complexity of the issue, further analysis is required. We will provide an update on our findings and the resolution plan by 06/03/2025.

If you have any additional insights or requirements, please let us know.

Regards,

Savithiri R.

Hi Rajkumar,

In the .NET Core platform, we use our own rendering technique to parse HTML elements and render them into PDF graphics. When HTML elements are included in grid cell values, we typically apply a background color to the cell before rendering the content. However, our current architecture does not support retaining the background color during pagination, leading to its loss when cell values containing HTML text elements are paginated.

We are actively analyzing the feasibility of maintaining background colors during pagination when grid cells contain HTML text elements. This requires evaluating additional use cases and the architectural complexities involved. Our analysis is ongoing, and we will provide further updates on March 10th, 2025.

Savithiri R.

 Cause :

Upon further analysis we found the cause for the issue , In the .NET Core platform, Syncfusion follows a specific rendering process where the background color of the grid cells is drawn first, and then the text inside the grid is processed separately as an HTML element.

If the text is too long to fit on the page, pagination occurs, moving the remaining text to the next page. However, this causes an issue:

1. On the first page, the background is drawn first, followed by the text.
2. When pagination happens, on the next page, the remaining text is drawn first, and then the grid with the background is rendered on top of it.

This results in the text becoming invisible or overlapped by the background, leading to the issue.

Hi Rajkumar,

As promised earlier, we have included the fix in .NET Framework platform for the reported issue where "Text overlapping occurs when setting a background color for PdfGrid cells" in our latest weekly NuGet release (v28.2.11).

 

Please use the below link to download our latest weekly NuGet:

NuGet Gallery | Syncfusion.Pdf.Net.Core 28.2.11

 

 

Cause :

In the .NET Framework, the HTML text element is converted into rich text and then rendered as a metafile, which includes a default background color. This results in an issue where the cell has an improper background color.

 

We sincerely thank you for your support and patience as we prepared this release. Please feel free to contact us if you need any further assistance.

Hi Rajkumar,

We regret to inform you that the fix for the issue "Text overlapping occurs when setting a background color for PdfGrid cells" could not be included in the 2025 Volume 1 release scheduled for tomorrow (26/03/2025) as planned. However, this fix will be included in the next weekly release, scheduled for the first week of April.

As per your request, we have prepared a custom patch with the fix in version 27.2.2. Please find the attachment for your reference.

Installation Steps:

1. Uninstall any existing Syncfusion packages from the sample project.
2. Delete the Syncfusion.Pdf.Net.Core package (version 27.2.2) from the .nuget folder.
• Folder path: C:\Users\xxx\.nuget\packages\Syncfusion.Pdf.Net.Core\27.2.2\
3. Install the Syncfusion.Pdf.Net.Core package from the provided custom patch.
4. Install the required dependency packages.

Please try the patch on your end and let us know the results.

 

Root Cause:

When the text exceeds the available space on a page, pagination occurs, moving the remaining text to the next page. However, this process causes an issue.

On the first page, the background is drawn first, followed by the text. However, when pagination occurs, the remaining text is rendered first on the next page, and then the grid with the background is drawn on top of it.

As a result, the text becomes invisible or overlapped by the background​, leading to the issue.

 

We sincerely apologize for any inconvenience this may have caused and appreciate your understanding. If you have any additional insights or requirements, please let us know.

Regards,

Savithiri R.
