Hi everybody,

I have a quite complex page with the GridView inside the UpdatePanel. When I select a record in the grid I activate the appropriate FormView (there are several different FormViews and the current FormView depends on Person type). I put all the FormViews into the UpdatePanel as well (otherwise they were not shown) with UpdateMode Conditional and trigger SelectedIndexChanged for the GridView.

So far so good.

I tested it at some point and everything worked smoothly. I then worked on other modules in the application and when I'm now trying to test this page I'm getting weird JavaScript errors (in IE) coming from autogenerated code.

I also have an additional question. I have a static public class with the following code

/// <summary>

/// Sets enabled property of the passed controls

/// </summary>

/// <param name="cc"></param>

/// <param name="enabled"></param>

((TextBox)control).ReadOnly = !enabled;

((DropDownList)control).Enabled = enabled;

((CheckBox)control).Enabled = enabled;

((RequiredFieldValidator )control).Enabled = !enabled;

Apply above for all type of validators you have used.

Hope it helps, let me know how it goes.

Yes, Please try and let me know if problem exists.

This is really bizarre! I commented out one of the validators with this code

Why I'm getting errors from the page that tries to access this control? It is commented out! Or may be I can not use <!-- --> comment style like this in a UserControl ?

Do you see a problem here?

Once I switched to ASP style comments in my UserControls the page started to work (I removed UpdatePanels though).

I have another weird problem in a different place. I'll update my other thread with more info.

Here is the weird part. When I try to open my form (when I'm using UpdatePanels), I'm getting an error here:

if (typeof(Page_Validators) == "undefined")

var i, val;

eval("val.evaluationfunction = " + val.evaluationfunction + ";");

}

In the debugger I see that I have 16 validators, but for some reason the 3rd [2] validator is null. I could not figure out what could be the problem.

The null validator is between FirstName, LastName validators and DOB validator.

Here is the UserControl ASPX definition:

<%--<%@ Register src="DateCombo.ascx" tagname="DateCombo" tagprefix="uc1" %>

<%@ Register Assembly="RJS.Web.WebControl.PopCalendar" Namespace="RJS.Web.WebControl" TagPrefix="rjs" %>

I see nothing's wrong here, so I don't understand where this null validator is coming from... And since this is auto-generated code I have no control over it.

The only solution is to comment out all update panels. Then the page works correctly, but I get the whole page refresh - that's the downside.

I don't have the same problem in FireFox. I think in FireFox this error is just silently ignored.

this error is due to missing brackets '}' in your javascript.

try this

function ValidatorOnLoad()
        {
            if (typeof(Page_Validators) == "undefined")
                return;

            var i, val;
            for (i = 0; i < Page_Validators.length; i++)
            {

                val = Page_Validators[i];
                if (typeof(val.evaluationfunction) == "string")
                { 
                    // The error is on this line
                    eval("val.evaluationfunction = " + val.evaluationfunction + ";");
                }
            }
        }

The JavaScript code is correct and this is not my code, otherwise I would just add an extra check

if (val)

..

The code is autogenerated by MS AJAX. But in my case for unknown reason I have an array of Page_Validators but some of them are null. I don't understand how did it happen and that's why I posted one of my UserControls, since I think the error is coming from it. At least 2 normal validators are from it, then one null, then again one from it.
