Methods

Name

Description

ApplyStyle(Style)

Applies a style to the area. When a style is applied - rather than set (see Range.SetStyle ) - only the differences between the new style and style properties previously assigned to the range (through the ExcelWriter API) will take effect. For example, if the range has a background color and the new style applied does not contain a background color, the area's color will not be affected.

ClearContent()

Clears the content of all cells in the range. Calling this method is equivalent to setting an range's style to "Normal" and its cell values to null.

JoinRange(Range)

Adds another range to this range.

RemoveConditionalFormat()

This method removes any ConditionalFormat objects from the Range.

SetConditionalFormat(ConditionalFormat)

This method copies the specified ConditionaFormat object and associates it with this Range. If any ConditionalFormat objects already exist within the Range, they will be removed and replaced by the specifed one.

SetDataValidation(DataValidation)

Assigns a data validation rule to all cells in the Range. If the DataValidation object uses a local reference or area in a formula (i.e. "=A5:B7"), then the range will adjust those local references accordingly based on the range's location. The original DataValidation object will not be affected.

SetStyle(Style)

Sets the style for every cell in this range. When a style is set - rather than applied (see Range.ApplyStyle ) - all previously assigned style properties, including font and number formatting, will be overwritten for all cells in the range.

ToString()

Returns a string representation of the Range object.
