Hello
This is extreme and custom but is it possible to trigger the full select of a cell content on addRow()?
Please, try to use the following code:
myGrid.addRow("qqq","[1,2,3,4,5,6,7,8]"); //adding a row
myGrid.selectCell(myGrid.getRowIndex("qqq"),1,false,true) //selecting the required cell of that row
setTimeout(function(){
myGrid.editCell(); //open the editor of that cell
myGrid.editor.obj.select() //selecting the value
},5)
