object not found error when clicking row in grid

[Chom]

Hi all

I am getting an error on my page when I try to load a popup window and have been trying for several days resolve this issue.

I have three hierarchy grids on my page one contains a grid binary image column.

Here is my code

Here is the issue:

Grid one (rgListings) has a Preview link in one of the columns which I use to open a new window through some javascript which is in a file on my project. When I add a listing into this grid and I click on the Preview link in the row the window pops open no problem.

But when I add a listing in the rgListings grid and then add an image in the second (rgSlides) grid that is where it comes to a halt. When I click on the Preview link in the rgListings grid to open the pop up window I get an object not found error and I do not know where to look. I think that I have pin pointed it to this javascript on in the markup, but I am not sure.

I think this is where the error is comming from, but not sure:

 

            function conditionalPostback(sender, eventArgs) {
                var theRegexp = new RegExp("\.UpdateButton$|\.PerformInsertButton$", "ig");
                if (eventArgs.get_eventTarget().match(theRegexp)) {
                    var upload = $find(window['UploadId']);

                    //AJAX is disabled only if file is selected for upload
                    if (upload.getFileInputs()[0].value != "") {
                        eventArgs.set_enableAjax(false);
                    }
                }
            }

            function validateRadUpload(source, e) {
                e.IsValid = false;

                var upload = $find(source.parentNode.getElementsByTagName('div')[0].id);
                var inputs = upload.getFileInputs();
                for (var i = 0; i < inputs.length; i++) {
                    //check for empty string or invalid extension
                    if (inputs[i].value != "" && upload.isExtensionValid(inputs[i].value)) {
                        e.IsValid = true;
                        break;
                    }
                }
            }

 

I have tried putting some jscript on the page to open the window with the btnPreview.Add.Attributes(“onclick”,  “showForm();”) which does open the pop up window but I still get that object not found error and 2 windows open. I also added a button in the grid in the item template and called the jscript window open using the OnClientClick which opens the window but I still get the object not found.

 

  Object expected  pricingoptions.aspx?un=AhXmBz0EmheYEWJuqM3wmw%3d%3d&cid=TcOtbnnIOsxq1CXOjfwSOw%3d%3d&bn=7XKB52RyE53nj0aY1w19usl3BDx+Or5DpGp+x+Z7g+E%3d, line 3 character 4

 

Hopefully some extra eyes might see my problem.

Hello Chom,

I checked your code however I could not fine the source of the problem there.
Could you please try opening a formal support ticket and send us a runnable sample there? We will debug it locally and thus try finding what could have gone wrong.

Thank you for your cooperation in advance.
