The ErrorText property indicates if there is an error in one of the cells in a row. If ErrorText is set to a value other than Empty, then an error glyph () is shown in the row header.
The default width of the row header includes enough room to display the error glyph, whether or not the glyph is displayed. If the row header size is adjusted so that there is not enough space to display the glyph completely, the glyph is not rendered.
Because row headers can display both text and glyphs, header content is displayed by priority, as follows:
Text displayed in the row header cell.
The editing glyph.
The error glyph.
For example, if the row width is decreased, the error glyph disappears first, then the standard glyph, then text.
