Remarks
When the user edits a cell value and commits the change, the DataGridView control calls this method to convert the displayed value from the FormattedValueType to the ValueType. The control then sets the underlying cell value or data source value to the converted value.
The default implementation of this method parses the formattedValue
parameter using the NullValue, DataSourceNullValue, and FormatProvider properties of the cell style indicated by the cellStyle
parameter.
If formattedValue
is equal to NullValue, this method returns the value of the DataSourceNullValue property or null
if DataSourceNullValue is DBNull.Value and the cell ValueType is a reference type.
If formattedValue
is not equal to NullValue, this method parses formattedValue
using the FormatProvider property and the specified or default converters.
If the cell ValueType is nullable, this method wraps the return value as a Nullable<T> type.
