Custom Validator无法获得Combobox ID(Custom Validator fails to get Combobox ID)

 我使用自定义验证器作为必需字段验证器失败的Ajax Combobox，但我无法解决Combobox，但是当我将自定义验证器控件中的另一个文本框的Id传递给验证选项时，它工作正常。 
 
 以下是我的代码：已更新 
 
<ajax:ComboBox ID="Cmbx" runat="server" Width="100px" CssClass="AquaStyle textfont"
                                                AutoPostBack="true" DropDownStyle="DropDown" AutoCompleteMode="SuggestAppend"
                                                CaseSensitive="false" ItemInsertLocation="Append"
                                                ValidationGroup="Validate" CausesValidation="true" />
 
 
<asp:CustomValidator ID="cvRequired" ControlToValidate="InstCmbx$TextBox" runat="server"
                                            ClientValidationFunction="validate" Display="None" ValidationGroup="Validate"/> 
 
 这不起作用，我也检查了Ajax网站上的问题跟踪器，但是他们说我必须在Id中添加“$ TextBox”并且它会起作用，但是它也不起作用。 
 
 我无法从相同的方式调用简单的javascript函数： 
 
 function validate(sender, args) {
       alert("gasfkgsjkds");
   }

I am using the custom Validator as Required Field validator fails for the Ajax Combobox, but I am not able to work it out for the Combobox, howeverr when I pass the Id of another Textbox in the custom Validator control to validate option, it works fine.
 
Below is my code:Updated
 
<ajax:ComboBox ID="Cmbx" runat="server" Width="100px" CssClass="AquaStyle textfont"
                                                AutoPostBack="true" DropDownStyle="DropDown" AutoCompleteMode="SuggestAppend"
                                                CaseSensitive="false" ItemInsertLocation="Append"
                                                ValidationGroup="Validate" CausesValidation="true" />
 
 
 
<asp:CustomValidator ID="cvRequired" ControlToValidate="InstCmbx$TextBox" runat="server"
                                            ClientValidationFunction="validate" Display="None" ValidationGroup="Validate"/> 
 
This is not working, I checked out the issue tracker on Ajax site as well, but they said that I must append "$TextBox" in the Id and it will work, but then also it is not working.
 
I am not able to call a simple javascript function from the same:
 
 function validate(sender, args) {
       alert("gasfkgsjkds");
   }
