I have a DataGridView and I should handle an event when a row (or any cell of a row) is clicked, yet I can't find anything like this. Is there a way to do this other than having each individual cell a handler method?
You may try the SelectionChanged event of Datagridview.
You have to set the SelectionMode property to FullRowSelect and check any change in the above event.
If necessary, you can get the rowindex using Datagridview.CurrentCell.Rowindex too.

I need to get access to all the values in a DataGridViewRow, once the user clicks on a cell of that row. I would like to do that from the CellClick event for the DataGridView
Datagridview1.Rows[e.RowIndex].cells[0].value

I am trying to make a cellEditEnd event method, in which I need the cell, that was edited. I could use the selectedCell function, but I would like to know how if there is a way to get the cell object inside the method.
You can handle the CellEndEdit event : https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.cellendedit(v=vs.110).aspx
Which takes a DataGridViewCellEventArgs as a parameter, this should provide you with the Row and Column index of the cell you need.
how to capture event when moving from one cell to another in same row.
You get the CurrentCellChanged event:
[...] when the value of the CurrentCell property has changed.
You'd have to check you were still on the same row, but it should do what you want.
How can I get the row leave event of a GridView?
The GridView does not have a row leave event.
See the list of existing events here.
When I change a value programatically in a DataTable that my DataGridView is bound to, the appropriate CellValueChanged event is not firing for the DataGridView. I'm trying to change a cell's background color based on cell value when the DataTable is filled with data without iterating through every row and checking each value.
You are changing the DataTable directly and expect DataGridView's event to be fired?
I suggest that you change the cell value programatically as:
DataGridView[ColumnIndex, RowIndex].Value = NewValue;
Additionally you will have to Call DataGridView.CommitEdit() to commit the values to the DataTable. This should trigger the CellValueChanged event.

Changing the cells background color should be done in the RowPrePaint-Event, this will be fired if the row is repainted, after the value change.
