iam trying to make edit mode activate after any postback or any page load but it doesnt seem like I can find a solution: I want to Activate the edit mode of the WebDataGrid and open the last row slected and opened row, when the user load the page .
i tried to get the current opened row and opened but it didn't work
var rowIndex = eventArgs.get_item().get_row().get_index();
var editingCore = row.get_grid().get_behaviors().get_editingCore();
var rowEditingTemplate = editingCore.get_behaviors().get_rowEditing();
I am sending you a sample where it works. Can you please modify it to your scenario to see why you have this error.
