I have created my custom DataGridViewNumericTextBoxColumn derived from DataGridViewTextBoxColumn class.
When I call
this.HeaderDataGridView.Sort = Sort.Programmiticaly; this.HeaderDataGridView.Sort(this.HeaderDataGridView.Columns[Utility.HEAD_X], ListSortDirection.Ascending);
It is working fine for integer type values but when the data contain double values it don't sort.
Thanks, Ashish
