问题描述
大家好，
我的应用程序中有combobox Incidenttype（组合框的标签）我正在进行验证，就好像有人没有在组合框，它会抛出IncidentType输入格式不正确的异常。
我想在事件类型中将Exception消息更改为Please Selcet值。
以下是我的代码。
Xaml
< toolkit：datafield isrequired =真正的label =事件类型verticalalignment =中心xmlns：toolkit =＃unknown>
< simstagcombobox verticalalignment =中心horizontalalignment =左身高=25宽=220tagtypeid =9selectedvalue ={Binding IncidentType，Mode = TwoWay}>
代码：
公开属性IncidentType作为Guid
获取
返回_guid1
结束获取
设置（值为Guid）
_guid1 = value
结束集
结束财产
请提供一些非常紧急的解决方案。
