Hello Jimmy,

Please find answers to your questions below.

1) Going to the Add New Row

If the grid is on focus you can go to the Add New Row with Shift + Tab (For example try seeting focus on the grid by clicking on some column header and then press Shift + Tab).

If the grid is out of focus you can use Tab, which will start focusing on every page element one by one starting from the browser's address bar. However this is not that suitable if the focus should go through a lot of elements until it reaches the Add New Row.

2) How can I bind custom keys for grid adding/editing functionality.

You can use the startEditTriggers property of the grid - http://help.infragistics.com/jQuery/2014.2/ui.iggridupdating#options:startEditTriggers. You can set it so that pressing the Enter key over a cell will trigger edit mode. This is the razor syntax to do this:

features.Updating().ShowDoneCancelButtons(false).StartEditTriggers(GridStartEditTriggers.Enter);

3) Will disabling "Done / Cancel" button affect exisiting functionality

Disabling the Done/Cancel button when autoCommit: false will not affect exisiting functionality. However in this case you will have to implement how the changes are commited. For an example how this can be done via a custom button please refer to this sample:

I hope this is helpful. Please do not hesitate to contact me if you have any further questions

Shift + Tab is not part of the keyboard navigation implementation of the igGrid. so it is expected it will not work in all scenarios, such as yours. I just suggested since there is a chance that it does the work for you. All keyboard combinations that are implemented can be found at http://help.infragistics.com/Help/Doc/jQuery/2014.2/CLR4.0/html/igGrid_Accessibility_Compliance.html

If you want to implement your custom shortkeys, you can use the jquery .keypress event and depending on which key is pressed (this can be checked via the browsers key codes) to programmatically enter edit mode of a cell, change selected cell, set focus on a element, etc. Your code shoud be similar to this:

$(document).on("keypress", function () {
   $("#accSelectionGrid").igGridSelection("selectRow", 0); 
});

Question 2. How can I specify multiple startEditTriggers in MVC

You separate the different options with | :

.EditMode(GridEditMode.Row).StartEditTriggers(GridStartEditTriggers.Enter | GridStartEditTriggers.F2);

Question 3.  How to set focus on Modal's grid programmatically and then use up/down arrow key

You are right, .focus() will not work on elements that are not capable of receiving focus by default. However you can add tabIndex attribute to the DOM element contaning the grid and then it will be able to receive focus using the .focus() method.

$("#accSelectionGrid").attr("tabIndex", "0");
$("#accSelectionGrid").focus();

I hope this helps. Please note that Infragistics policy is to open a new thread for every different issue that customers have. This makes searching and tracking easier and enables us to provide better support. Please keep this in mind regarding any future issues that you face.
