I am still having problems with the default value. I cannot seem to set a default value for the checkbox column. I keep getting the standard blue box. And I hate to have to loop through it to set the value to false.

that solved it,

thanx 

It is possible that the DataColumn with which the cell you are trying to edit is associated is ReadOnly.

 Im new to Infragistics controls. Im having problem with the Wintree control. I have a tree that is databound and I wanna be able to edit some of the data. I have changed the CellClickAction so I can edit the cell. But then i leave the cell I get a mesage that its read only. I have tried to change AllowCellEdit to full, but still the same problem. Does any one know how to fix it?
