I found many solutions, but neither doesn't work. I have the latest version 4.7.0. In example this: focus cell inline editing.
My solution is [code is in coffeescript]:
ondblClickRow: (rowId, iRow, iCol, e) ->
if rowId and rowId isnt lastSelectedRowId
table.jqGrid 'editRow', rowId, true
$("input, select, textarea", e.target).focus()
lastSelectedRowId = rowId
Doesn't jqGrid have impelemented how to select of cell during inline editing?
Note for Oleg: Please, look at my last comment again jqgrid (converting datatypes)
