c# - column header text changes after change DataSource? -

when change datasource of datagridview datatable don't have rows, , after change datasource datatable contains rows, header text changes , properties width...

try using bindingsource control between datagridview , datatable. bindingsource control has useful property called filter filter out unwanted rows without creating new datatable object or otherwise affecting structure of underlying datatable, datagridview's headers not affected.

you can either manually through code or drop instance of bindingsource in designer. code this:

bindingsource bs = new bindingsource(); bs.datasource = yourdatatable; yourgridview.datasource = bs; 

then can filter out results doing:

bs.filter = "some_column = 'some_value'";
