DataGridView custom column - customization lost on datatable refresh




I am using custom column (Wisej control consisting of 3 text boxes verticaly aligned),

on initial window open, when data table is filled, table OK and table contains required columns.

If I am trying to refresh data in the underlying data grid table (dataset.datatable.Fill ) table is redraw correctly if number of returned rows is reducing.

If I try to refresh data table so that number of returned records is greater than it was before, data table is loosing custom column, it is not  drawn at all, only thing helping is to close and re-open window again

Please can you take a look,

Hi Dino,

Any chance for a small sample? Also are you setting the DataGridView’s RowCount somewhere? If I remember correctly we made a sample for you using a Custom Cell Renderer.

Let me know!
