Absolutely, after reviewing the API documentation provided right here:
http://angular-ui.github.io/ng-grid/
In the section labeled: API documentation
You will find the specific option
enableCellEdit false
This option globally enables editing for all cells. If editing is not desired, you can utilize the editableCellTemplate option to customize the default text input Link
If editing is not required as per your request, you can turn this option off. Additionally, if you wish to capture information from the clicked cell, you can achieve this by using
beforeSelectionChange function (rowItem, event) { return true; }
Within the ng-grid options, you can employ this function to call one of your custom functions, providing you with the necessary rowItem information.
