Disabling sorting on selected columns [message #1065399]

Hi,

I am using tree grid in my application and I want to enable sorting only on specific columns. To achieve this I have added label(say SORT) on columns that I want sorting to be enabled and registered this attribute

configRegistry.registerConfigAttribute( SortConfigAttributes.SORT_COMPARATOR, new DefaultComparator(), DisplayMode.NORMAL,	"SORT"  );

To disable sorting on columns, I have registered NOSORT label.

configRegistry.registerConfigAttribute( SortConfigAttributes.SORT_COMPARATOR, new DefaultComparator(), DisplayMode.NORMAL,	"NOSORT"  );

As specified in the example single click sorting is enabled like,

nattable.addConfiguration( new SingleClickSortConfiguration() );

But this enables sorting on all columns. Is this the correct way to disable sorting?

Sorry the code had the type when I pasted here. For NOSORT, I registered new NULLComparator.

Also When I use DebugMenuConfiguration I correctly see the SORT and NOSORT labels on the columns. But I do not see these lables on column header, is it also needed there to work correctly?

Well it works in the SortableGridExample. It might be just an issue with your composition. Maybe double check the example with your code.

Okay, I figured out the problem. I had the CellLabelAccumulator(implementing IConfigLabelAccumulator) which adds the labels to the data layer(all my labels are added in this class and it works well). But the sorting header configuration does not work based on this configuration, but it works if I add the ColumnOverrideLabelAccumulator on the ColumnHeaderDataLayer. Its okay for me to add the label in two places, but just want to know if this is a bug or by design.

Why should it be a bug? The header layer stack is different to the body layer stack. They are different regions and therefore different cells where you apply your labels. I don't understand why you need to add the label in two places.

By two places, I meant I had to register the "Sort" and "NoSort" labels on the column header layer and the other labels(to set combo box editors, styling) on the body layer. Since in the cell state accumulator, I have the column indexes, I assumed setting "Sort" and "NoSort" labels would work, but it looks like it does set to the header cells.
