为什么继承自DataGridViewColumn的自定义Column总是无法保存属性值
public class TXDataGridViewNumericColumn : DataGridViewColumn
{
public TXDataGridViewNumericColumn() : base(new TXNumericCell())
{
this.InputType = NumericType.Integer;
this.CellTemplate=new TXNumericCell();
}
public override DataGridViewCell CellTemplate
{
get
{
return base.CellTemplate;
}
set
{
if (value != null &&
!value.GetType().IsAssignableFrom(typeof(TXNumericCell)))
{
throw new InvalidCastException("Must be a NumericCell");
}
base.CellTemplate = value;
}
}
private NumericType m_NumericType;
public enum NumericType
{
Decimal,
Integer,
PositiveDecimal,
NegativeDecimal,
PositiveInteger,
NegativeInteger
}
public NumericType InputType
{
get { return m_NumericType; }
set { m_NumericType = value; }
}
}
当在datagridview的列编辑器中选择列的InputType属性时(在设计模式时)，其值不可以保存？请问哪里有问题？谢谢！
