The following code example demonstrates how to use the Sort in a programmatic sort. The object specified by the DataSource property has a SupportsSorting property value of false. The object specified by the DataSource property does not implement the IBindingList interface. The VirtualMode property is set to true and the IsDataBound property of the specified column returns false. When you provide your own data source by implementing virtual mode, you must also handle the sorting operations yourself.Ĭalling this method automatically sets the CurrentCell property to null. When you bind the DataGridView control to an external data source, you must use the sorting operations provided by that data source. This method works only when the DataSource property is not set. When sorting by columns set to programmatic sort mode, you must display the sorting glyph yourself by setting the DataGridViewColumnHeaderCell.SortGlyphDirection property. In this case, you will typically set the DataGridViewColumn.SortMode property to DataGridViewColumnSortMode.Programmatic to disable automatic sorting and to leave room for a sorting glyph. In order to implement a highly customized sorting operation, you can write an event handler for the ColumnHeaderMouseClick event and call this method with an instance of a class that implements the interface as a parameter. This method allows advanced customization of the sorting feature of the DataGridView class.

private void Button1_Click( object sender, EventArgs e )ĭataGridView1.Sort( new RowComparer( SortOrder.Ascending ) ) ĭataGridView1.Sort( new RowComparer( SortOrder.Descending ) ) In this example, the IComparer interface is implemented in the RowComparer class. The following code example demonstrates how to use the Sort method overload in a multiple column sort scenario.
