Question

I have a grid backed by a grouping store in which I have a column that I use a custom renderer.

In that custom renderer, I break apart the value in the column and use it to construct a panel in the cell.

I want to have the group action group by only one part of the value I pass to the cell, ie:

to this one column, I pass a string like this:

a|2|somestring
a|3|someotherstring
b|1|thirdstring

which I want to be grouped as:

a|2|somestring
a|3|someotherstring

b|1|thirdstring

but default grid behavior is to group as:

a|2|somestring

a|3|someotherstring

b|1|thirdstring

as they’re all unique strings.

To do this, It’d be awesome if there were a function I could override for that cell that would let me retrieve the string for comparison.

Is this possible?

Answer 1

Ext.grid.Column#groupRenderer is the function used to define what the column is grouped by. I can process the string stored in the column and return what I want the column grouped into.

Thanks to Jaitsu for getting me looking in the right place.
