Here Mudassar Ahmed Khan has explained with an example, how to access complex nested JSON objects in Angular JS.

Complex nested JSON objects comprises of a JSON object array and each object of the JSON array consisting of another child JSON object array.

Is Bound Using Data Source ID; Grid View Update Event Handler handler1 = (Grid View Update Event Handler) base.

Get String("Grid View_Unhandled Even t", new object[] { this.

All samples of course assume you’re doing everything in your page, but I have to do everything in my code-behind, because on forehand I don’t know what I’ll be binding to my Grid View.

Check out what I’m trying to do, maybe you can help?

This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.

A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.

But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.

You're accessing so many items without null checks that it could be any number of things. Are you sure all of the controls exist in the cells you're specifying?

event is raised when a row's Update button is clicked, but before the Grid View control updates the row.

For example a Sql Data Source, which is automatically added to your Web Form if you drag-n-drop your way around Visual Studio 2005.

The problem is, I’d very much like to do so, if ASP. But I can’t set a Data Source property or anything on the Sql Data Source!!! I probably have to read the cells on the Grid View of the selected row, find the controls, get the values from those and insert those into my Data Set. Every one can use it to compare the new value with old ones.
