Diiferent Editing Controls in one column in WPF DataGrid

Hi All,

I have a datatable like follows. Items and DataType are two columns.

Items| DataType | Value
-----------------------------------
A I 5
B S Test
C S WPF Grid
D B true
E I 2451
F B false


I want to bind the DataTable to a WPF DataGrid. I want to have different editing controls on a Value column based on the DataType Column.

If I edit first and second row row, it has to be the text column, where as If I edit 4 & 6 row ... it has to be the combobox column with true/false are the items of the combobox...

Any suggestions much appreciated...
