Korean Text AutoSize Issue in Wisej 4

Hi Julie,

I’ve attached the sample source code as requested. As you suggested, I removed the .vs bin and obj folders to reduce the file size. Please check it out and let me know if you can identify the text sizing issue in the FlowLayoutPanel.

Thank you.

Hi Julie,

Thank you for the quick response and for confirming the issue with Labels.

I see you tested with controls placed directly on the form, but the main issue I reported occurs specifically when controls are inside a FlowLayoutPanel. I’ve created a test project and captured a screenshot that clearly demonstrates this issue.

As you can see in the attached screenshot:

Top section (FlowLayoutPanel):

• “한국어 버튼” – text is broken into 2 lines when it should be on 1 line
• “En Button” – while not wrapped, appears to have different padding/sizing compared to the same button outside FlowLayoutPanel
• “안녕하세요” – text is split into 2 lines unnecessarily
• “label1” – English text displays correctly
• “한국어 버튼입니다” – the Label is wrapped into 2 lines when it should display on a single line

Bottom section (directly on form):

• Button “En Button” – displays correctly with normal padding
• Button “한국어 버튼입니다” – displays on a single line as expected
• Button “안녕하세요” – shows correctly on one line
• Labels with borders clearly show wrong AutoSize behavior

Key Findings:

1. The FlowLayoutPanel has severe font metrics calculation issues for Korean text and perhaps English too, particularly with padding/sizing
2. Even English controls show inconsistent sizing/padding behavior within FlowLayoutPanel
3. Korean text that displays perfectly on the form becomes unnecessarily wrapped inside FlowLayoutPanel

Impact:

• In Wisej 3: All text (Korean and English) maintained consistent sizing and displayed correctly
• In Wisej 4: FlowLayoutPanel’s layout calculations are fundamentally broken
• This breaks our entire UI design pattern for dynamic forms

The screenshot clearly shows that System.Drawing.Managed’s text measurement is critically flawed, especially within FlowLayoutPanel’s layout engine.

I’ll try again to upload the complete sample project along with this screenshot. This prevents us from migrating to Wisej 4 for our Korean market applications.

Best regards,

Bill Kim

Thanks for reporting this. I tested and I was able to reproduce with a label but not with a button. We’ll look into fixing this.
Can you try to post your sample please?
To solve the “forbidden” error message, try reloading the page, or closing and reopening the browser. Also make sure that you delete the .vs bin and obj folders from your sample so that the filesize is smaller.
