Member Function Documentation

override object MaxCustomControls::ExplorerListData::ConvertValue	(	object	value,
		object	columnID
	)		[inline, protected]

Override ConvertValue to check that a TypeConverter associated with a type can properly ConvertTo the desired type.

The base DevExpress implementation will look for a TypeConverter on the destination column, but it doesn't check that the TypeConverter can actually converter to the column's type, or even if that conversion is necessary.

Parameters:

value	Edit value to set in the column.
columnID	Id for the destination column.

Returns:

The converted value.
