The Glyphs property returns a C1.Win.C1TrueDBGrid.GridGlyphs collection with an indexer of type C1.Win.C1TrueDBGrid.GlyphType. This collection allows you to get or set the images used to indicate column sorting, collapsed and expanded outline groups, check boxes, etc.
Note: Setting a glyph to null restores the default (built-in) image. If you want to make a glyph invisible, set it to a small blank image instead.
c1trueDBGrid.Glyphs[GlyphType.SortAscending] = imgAscending; c1trueDBGrid.Glyphs[GlyphType.SortDescending] = imgDescending;
