Assembly: Microsoft.Office.Interop.Excel (in microsoft.office.interop.excel.dll)
The FormatCondition object is a member of the FormatConditions collection. The FormatConditions collection can contain up to three conditional formats for a given range.
Use FormatConditions(index), where index is the index number of the conditional format, to return a FormatCondition object.
Use the Add method to create a new conditional format. If you try to create more than three conditional formats for a single range, the Add method fails. If a range has three formats, you can use the Modify method to change one of the formats, or you can use the Delete method to delete a format and then use the Add method to create a new format.
Use the Font, Borders, and Interior properties of the FormatCondition object to control the appearance of formatted cells. Some properties of these objects aren’t supported by the conditional format object model. The properties that can be used with conditional formatting are listed in the following table.
The accounting underline styles cannot be used.
The following border styles can be used (all others aren’t supported): xlNone, xlSolid, xlDash, xlDot, xlDashDot, xlDashDotDot, xlGray50, xlGray75, and xlGray25.
The following border weights can be used (all others aren’t supported): xlWeightHairline and xlWeightThin.
