How Do I Sort By A Column?
Using the Property Inspector
Select the data grid and open the property inspector. Navigate to the Columns pane (1), select the column you want to modify (2), and check the Sort by column checkbox (3).
Using Script
You can sort by column setting the dgProp["sort by column"] property of the data grid to the name of the column you want to sort by.
set the dgProps["sort by column"] of group "DataGrid" to "Name"

How do I change the direction of the sort using a script?

Is there any way to make collum sort permanent? it mean, we update dataGrid by script (not user click), sort still work automatically. Yes it is there is sort by script above, but after update we have to run that script again and again and it make the speed slower. Thanks

Adding the following empty handler
on SortDataGridColumn pColumn
end SortDataGridColumn
to the Datagrid script should do what you want.

@Ben.Brannen
There are several ways to do it.
You can use the property dgColumnSortDirection
set the dgColumnSortDirection["col1"] of group "Data Grid" to "ascending"
possible values are ascending or descending
or you could use the command SortDataByKey
dispatch "SortDataByKey" to group "DataGrid 1" with pArrayKey, pSortType, pDirection, pCaseSensitive
where
pArrayKey is the columname
pSortType can be numeric,text,international, datetime
pDirection can be ascending, descending
pCaseSensitive can be TRUE, FALSE

Hm,
i just tried it here again. Without that handler i can click on the columns header to sort and sorting works. If i add the two lines to my Datagrid script , then clicking on the columns headers to sort does not work.

Hi Gilar
You should be able to resort after adding update the content by using the SoryByColumn command e.g.
dispatch "SortByColumn" to group "DataGrid" with "name"
I hope that helps.
Kind regards

Hi @Elanor Buchanan
I have tried this
dispatch "SortByColumn" to group "DataGrid" with "name"
but it make data grid slow,
FYI: my apps get data feed and update about 80 line/second.
so i update about 80 times / second
it feel slow when i have to run sort script every time update
