insert a value in a matrix's cell

Hi,

after I've added a new row into my matrix I set the values in its cells as follow:

((SAPbouiCOM.EditText)mx.Columns.Item("MyColName").Cells.Item(mx.RowCount).Specific).Value = "MyCustomValue";

It don't work fine just if the cell I'm filling with the value is binded with a DATE table's column.

For example I try:

((SAPbouiCOM.EditText)mx.Columns.Item("MyColName").Cells.Item(mx.RowCount).Specific).Value = "01.01.2005";

but it not work fine.

Suggestions?

Thanks in advance.
