c# - WPF DataGrid not displaying values of DataTable in certain columns -


i've got program doing processing of csv file , it's producing datatable output. i'm binding datagrid so:

<datagrid name="gridtable" itemssource="{binding outputdata}" />

everything seems work fine. datatable produced, datagrid get's updated. inexplicably columns (type double) don't seem display data. first column (type int) works fine: datagrid

when double check datatable structure it's there, , correct type. i'm getting no exceptions:

datatable

the data binding works it's showing columns , has correct value in first column.

has come across before? cheers

did use 

<datagrid.columns> <datagridtextcolumn header="" binding="{binding }"/> </datagrid.columns>

it should handle doubles no problem
