是否可以动态定位ValidatorCalloutExtender？

Question

我有两个通过VB.net编程的ajax验证器标注扩展程序。我正在验证一个文本框，但我希望弹出窗口显示在不同的文本框旁边。我怎样才能告诉ajax弹出窗口在哪里出现？

Dim custval As New CustomValidator 
    custval.ID = "ValidPage" 
    custval.ErrorMessage = "<font color=red>Please Enter a 'To' Date" 
    custval.SetFocusOnError = True 
    custval.ForeColor = Drawing.Color.Red 
    custval.EnableClientScript = True 
    custval.ControlToValidate = cell.Controls(18).ID 
    custval.ClientValidationFunction = "ClientValidate" 
    custval.Display = ValidatorDisplay.None 
    Dim custvalex As New AjaxControlToolkit.ValidatorCalloutExtender 
    custvalex.ID = "VCEcustval" 
    custvalex.TargetControlID = "ValidPage" 
    custvalex.HighlightCssClass = "validatorCalloutHighlight" 
    '--------------------------------------------------------------- 
    Dim custval2 As New CustomValidator 
    custval2.ID = "ValidPage2" 
    custval2.ErrorMessage = "<font color=red>Please Enter a 'From' Date" 
    custval2.SetFocusOnError = True 
    custval2.ForeColor = Drawing.Color.Red 
    custval2.EnableClientScript = True 
    custval2.ControlToValidate = cell.Controls(23).ID 
    custval2.ClientValidationFunction = "ClientValidate2" 
    custval2.Display = ValidatorDisplay.None 

    Dim custvalex2 As New AjaxControlToolkit.ValidatorCalloutExtender 
    custvalex2.ID = "VCEcustval2" 
    custvalex2.TargetControlID = "ValidPage2" 
    custvalex2.HighlightCssClass = "validatorCalloutHighlight" 
    cell.Controls.Add(custval) '27 
    cell.Controls.Add(custvalex2) '28 
    cell.Controls.Add(custval2) '29 
    cell.Controls.Add(custvalex) '30 


function ClientValidate(sender, args) { 
    // Get Both form fields 
    var hid = $get('<%=HiddenField1.ClientID%>'); 
    var hid2 = $get('<%=HiddenField2.ClientID %>'); 
    var hidval = hid.value; 
    var hid2val = hid2.value; 
    var txtdate1 = $get(hidval); 
    var txtdate2 = $get(hid2val); 
    // do you client side check to make sure they have something 
    if (txtdate1.value != '' && txtdate2.value == '') { 
     args.IsValid = false; 
    } 
    else { 
     args.IsValid = true; 
    } 
} 
function ClientValidate2(sender, args) { 
    // Get Both form fields 
    var hid = $get('<%=HiddenField1.ClientID%>'); 
    var hid2 = $get('<%=HiddenField2.ClientID %>'); 
    var hidval = hid.value; 
    var hid2val = hid2.value; 
    var txtdate1 = $get(hidval); 
    var txtdate2 = $get(hid2val); 
    // do you client side check to make sure they have something 
    if (txtdate2.value != '' && txtdate1.value == '') { 
     args.IsValid = false; 
    } 
    else { 
     args.IsValid = true; 
    } 
} 

我知道那两个javascript函数可以分开。但是，我怎样才能移动弹出窗口？

您可能需要通过CSS或JavaScript来控制它的位置。我不知道通过服务器控件的属性来完成它的方法。

Here is a forum thread显示如何使用callout的set_x和set_y javascript方法重新定位验证器弹出窗口。
