C# 在代码隐藏中从CustomValidator获取ControlToValidate属性

我想从代码隐藏中获取ControlToValidate属性，这是我的aspx

<asp:CustomValidator runat="server" ID="custtxtTest" OnServerValidate="custtxtTest_ServerValidate" ControlToValidate="txtTest" ForeColor="Red" Text="*" />

我检查了，但这仅适用于客户端函数，不适用于代码隐藏。

这应该可以：

var validator = (source as CustomValidator);
string controlToValidate = validator.ControlToValidate;            
TextBox txt = validator.NamingContainer.FindControl(controlToValidate) as TextBox;

问候,， 乌罗斯

var validator = (source as CustomValidator);
string controlToValidate = validator.ControlToValidate;            
TextBox txt = validator.NamingContainer.FindControl(controlToValidate) as TextBox;
