Is it possible to do bulk update in editable grid

You can have a button or link (outside of the grid) which, when clicked, sets the values on every row (for a particular column) to some set value, or even a user-entered value.  This is not that difficult, but depends on exactly what you want to do and what you mean - you might need to provide more detail if you want a more specific or useful answer.

Hi,

I am able to acheive that, posting sample code for other people's reference.

selectionValue: local!selectedIndices,
/* Flatten the selected values so the result is easier to work with */
/* when the select/deselect all option is used in an editable grid */
selectionSaveInto: {
a!save(
local!selectedIndices,
a!flatten(save!value)
),
a!save(
local!selectedValues,
local!employeeData.data[local!selectedIndices]
)
},
selectable: true,
