Is it possible to bind complex type properties to a datagrid?

by

Allright guys… This question was posted waaay back but I just found a fairly nice & simple way to do this by using reflection in the cell_formatting event to go retrieve the nested properties.

Goes like this:

    private void Grid_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {

        DataGridView grid = (DataGridView)sender;
        DataGridViewRow row = grid.Rows[e.RowIndex];
        DataGridViewColumn col = grid.Columns[e.ColumnIndex];
        if (row.DataBoundItem != null && col.DataPropertyName.Contains("."))
        {
            string[] props = col.DataPropertyName.Split('.');
            PropertyInfo propInfo = row.DataBoundItem.GetType().GetProperty(props[0]);
            object val = propInfo.GetValue(row.DataBoundItem, null);
            for (int i = 1; i < props.Length; i++)
            {
                propInfo = val.GetType().GetProperty(props[i]);
                val = propInfo.GetValue(val, null);
            }
            e.Value = val;
        }
    }

And that’s it! You can now use the familiar syntax “ParentProp.ChildProp.GrandChildProp” in the DataPropertyName for your column.
