Hello,

I have requirement where we need to set the perticular background color when we select the group of column. It means, The column color shall differentiate between the selected and non-selected columns.

Ina nattable where we have hierarchical structure and non hierarchical structure,
we set the Background color(gray) to the tree structure(hierarchical structure ) and default (white) to non hierarchical structure.

I have tried to set the background color using 'configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_STYLE,selectionCellStyle,DisplayMode.SELECT); '.

But this color sets only the non hierarchical structure in the body as this is configregistry for Nattable not the tree.

Question is: What I need to do to change the background color for hierarchical structure as well to the selected columns.

Could you please suggest?

You need to register the style also for DisplayMode#SELECT in combination with the label TreeLayer#TREE_COLUMN_CELL

Hello Dirk,
Thanks for your help.

I tried with the sugggested approach (configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_STYLE,selectionCellStyle,DisplayMode.SELECT,TreeLayer.TREE_COLUMN_CELL); ) but it seems only the first colum is
changing it's background color.

Does it consider the TreeLayer.TREE_COLUMN_CELL equals the first column or I am missing something??

How Can I change the background color for selected portion either hierarchical or non hierachical structure?

Could you please help???

Yes

I don't understand your question. What do you mean with hierarchical and non hierarchical structure?

As I said before, you need to register for DisplayMode#SELECT AND for DisplayMode#SELECT in combination with TreeLayer.TREE_COLUMN_CELL. So you need to register the style two times. Or ensure there is no style registered for TreeLayer.TREE_COLUMN_CELL anywhere. If that doesn't fit your needs, I don't know what to suggest since I don't understand what you are trying to do then.
