Hello mcseidel,

Below you can find the answers of the requirements you have:

1.) Every column you want to be read only you have to set the readOnly option to true explicitly in the column settings;

2.) To enable a checkbox for single Boolean column you can set the format option with “checkbox” value. And if you want a different options in the dropdown of the other column you can define a text editor with dropdown with the desired options. However if you choose “Yes” or “No” this will be in the editor. So at editRowEnding event we change the value of the editor back to the desired Boolean ones.  The code snippet below demonstrates the approach:

{
    columnKey: "read",
    editorType: "text",
    editorOptions: {
        button: "dropdown",
        listItems : [
           "Yes",
           "No"
        ],
        keypress: function(evt, args){
            evt.preventDefault();
        },
        textChanged: function (evt, args){
            var dataSource = $("#grid1").data('igGrid').dataSource;
            // your custom code here
        }
    }
}

3.) Currently we do not have functionality that can fulfill your requirements but we are working towards improving this. You can expect it in one of our future volume releases. For now I can propose you a workaround. The basic idea is to override the setValue function of the checkbox and in it run your custom code. Example here:

var origfun = $.ig.EditorProviderCheckbox.prototype.setValue;
$.ig.EditorProviderCheckbox.prototype.setValue = 

function (val, updating) {
    if (updating) {
        val = !this.value;
    }
    origfun.call(this, val, updating);
    var dataSource = $("#grid1").data('igGrid').dataSource;
    // your custom code here.
}

4.) For the other column bind to textChanged event and then execute your custom logic.

I updated the sample to demonstrate everything I explained.

I hope this helps!
