Clear filters in TreeGrid

Suite and Optimus Suite 5
#1

I need to clear (blank out) all filters in my tree grid.

This is done easily for plain greed but same code does not work for tree grid and I can’t find a simple way of doing that.

Here is the code that works for plain grid:

for (var i=0; i < grid.filters.length; i++) {
  var filter = grid.getFilterElement(this.grid.filters[i][1]);
  if (filter != null) filter.value = '';
}

For TreeGrid, both grid.filters and grid.getFilterElement(n) don’t work.

while it must work with treegrid, as treegrid and plain grid shares filtering functionality, it will be better to change it a bit

for (var i=0; i < grid.getColumnCount(); i++) { var filter = grid.getFilterElement(i); if (filter) filter.value = ''; } grid.filterByAll();
