I created a grid and I have filled with CExtGridCellNumber type cells.

I have some questions about...

1) How to change the type of numerical data of this type of cell (ex. int, double) before placing a value in the cell?

2) How to obtain data directly to the type, for example if we have a CExtGridCellNumber with integer data, is possible obtain directly the integer value of the cell? Or you can only get as text and then convert it?

3) If the cell is of type CExtGridCellNumber, for example with double data, when someone type characters, how alert the user that only actual data type are accepted, is there a function that checks for incoming data type?

4) Is there a function that checks if a numerical value is within certain limits?

5) The grid have iterators of cells? To use it to extract data from the grid to another container ...
