handycontrol中NumericUpDown无法显示自定义错误提示的解决办法

最新的版本，好像是3.2.

NumericUpDown控件设置了ErrorStr属性，不管是否带hc名称空间，设置的字符串都不会生效，看了下源码，修改了NumericUpDown.cs中的一句，如下：

官方源码

public virtual bool VerifyData()
        {
            OperationResult<bool> result;

            if (VerifyFunc != null)
            {
                result = VerifyFunc.Invoke(_textBox.Text);
            }
            else
            {
                if (!string.IsNullOrEmpty(_textBox.Text))
                {
                    if (double.TryParse(_textBox.Text, out var value))
                    {
                        if (value < Minimum || value > Maximum)
                        {
                            result = OperationResult.Failed(Properties.Langs.Lang.OutOfRange);
                        }
                        else
                        {
                            result = OperationResult.Success();
                        }
                    }
                    else
                    {
                        result = OperationResult.Failed(Properties.Langs.Lang.FormatError);
                    }
                }
                else if (InfoElement.GetNecessary(this))
                {
                    result = OperationResult.Failed(Properties.Langs.Lang.IsNecessary);
                }
                else
                {
                    result = OperationResult.Success();
                }
            }

            SetCurrentValue(ErrorStrProperty, result.Message);
            SetCurrentValue(IsErrorProperty, ValueBoxes.BooleanBox(!result.Data));
            return result.Data;
        }

修改后

public virtual bool VerifyData()
        {
            OperationResult<bool> result;

            if (VerifyFunc != null)
            {
                result = VerifyFunc.Invoke(_textBox.Text);
            }
            else
            {
                if (!string.IsNullOrEmpty(_textBox.Text))
                {
                    if (double.TryParse(_textBox.Text, out var value))
                    {
                        if (value < Minimum || value > Maximum)
                        {
                            result = OperationResult.Failed($"范围{Minimum}-{Maximum}");
                        }
                        else
                        {
                            result = OperationResult.Success();
                        }
                    }
                    else
                    {
                        result = OperationResult.Failed(Properties.Langs.Lang.FormatError);
                    }
                }
                else if (InfoElement.GetNecessary(this))
                {
                    result = OperationResult.Failed(Properties.Langs.Lang.IsNecessary);
                }
                else
                {
                    result = OperationResult.Success();
                }
            }

            SetCurrentValue(ErrorStrProperty, result.Message);
            SetCurrentValue(IsErrorProperty, ValueBoxes.BooleanBox(!result.Data));
            return result.Data;
        }
