PoisonDataGridView Custom Theme Color change

[Piece-kun]

Greeetings!
I'm working with PoisonDataGridView and would like to use a custom color scheme.
I have stumbled upon this discussion however it appears that PoisonStyleManager does not have similar structure nor xml files...

I have set these parameters and changed the defeault columns and row header styles...

However, when I run the application, the colors are reset to the default theme colors. It seems like something is reapplying the theme after initialization. I could not locate where the themes are stored for the poison locally to edit them ether...

What is the recommended way to make custom colors persist for poison theme? Should I be using a different approach, or is there a way to prevent the theme from overriding my settings?

Thanks in advance for any guidance!

Hi! Thanks for reporting this.

You're right — PoisonDataGridView had a bug where the StyleGrid() method was unconditionally overwriting all color properties whenever the theme was applied (including during PoisonStyleManager initialization at runtime). This means any custom colors set in the designer were being reset, regardless of the UseCustomBackColor / UseCustomForeColor flags.

This has been fixed. StyleGrid() now respects those properties, consistent with how other Poison controls (like PoisonButton) handle custom colors.

To use custom colors on PoisonDataGridView, set these properties:

poisonDataGridView1.UseCustomBackColor = true;  // preserves your custom background colors
poisonDataGridView1.UseCustomForeColor = true;   // preserves your custom foreground colors

Or set them via the Properties panel in the designer under the "Poison Appearance" category.

Once these flags are set to true, the theme engine will skip overriding your custom BackColor, BackgroundColor, GridColor, header styles (ColumnHeadersDefaultCellStyle, RowHeadersDefaultCellStyle), DefaultCellStyle, and selection colors — so your designer-set values will persist at runtime.

The fix will be available in the next release.
