This function forces the dgs gridlist to carry out sorting once ( Sorting function and sorted column must exist, or it will do nothing and return false ).

Required Arguments

  • gridlist: The grid list in which you wish to sort.

Returns

Returns true if succeed in carrying out sorting, false otherwise.

Example

DGS = exports.dgs

local sortfnc = [[
	local arg = {...}
	local a = arg[1]
	local b = arg[2]
	local column = dgsElementData[self].sortColumn
	local texta,textb = a[column][1],b[column][1]
	return texta < textb
]] -- Define our sorting function

gridlist = DGS:dgsCreateGridList(300,50,600,600,false)
DGS:dgsGridListSetSortFunction(gridlist,sortfnc) -- set and load the sorting function
DGS:dgsGridListSetSortColumn(gridlist,2) -- choose which column to be sorted by.

DGS:dgsGridListAddColumn(gridlist,"test1",0.3)
DGS:dgsGridListAddColumn(gridlist,"test2",0.2)
for i=1,50 do
	local row = DGS:dgsGridListAddRow(gridlist)
	DGS:dgsGridListSetItemText(gridlist,row,1,tostring(i))
	DGS:dgsGridListSetItemText(gridlist,row,2,50-tostring(i))
end
DGS:dgsGridListSetAutoSortEnabled(gridlist,false) -- turn off auto sorting, so that it won't sort itself after row data changes.

setTimer(function()
	DGS:dgsGridListSort(gridlist) -- Sort the grid list after 1 sec
end,1000,1)
