[Solved] nodeCheck does not work

[Stefan]

Hi,

in our application, the following Javascript code works fine:

filterTree.nodeCheck(this, true);

We can check the nodes in our TreeView but we can not uncheck them.

filterTree.nodeCheck(this, false); // does not work

The nodeCheck call is just does nothing. I build a small application to reproduce the problem. The interesting thing is: in the test-application the uncheck works for the first time - but not for any further tries. We have no idea what the problem could be, please let us know if you have any idea.


Thanks in advance.
Stefan

Hello Stefan,

 
This is a known issue, which I am glad to inform you will be addressed in the next internal build of Telerik Extensions for ASP.NET MVC, which is available only for customers.

To fix problem manually, you will need to change this method in telerik.treeview.js:

nodeCheck: function (li, isChecked) {
            $(li, this.element).each($.proxy(function (index, item) {
                var $item = $(item).closest('.t-item'),
                    $checkboxHolder = $("> div > .t-checkbox", $item),
                    arrayName = this.element.id + '_checkedNodes',
                    index = $checkboxHolder.find(':input[name="' + arrayName + '.Index"]').val(),
                    checkbox = $checkboxHolder.find(':checkbox');

                $checkboxHolder.find(':hidden').filter(function() {
                    // use filter because of nested square brackets
                    return ($(this).attr("name").indexOf(arrayName + '[' + index + '].') > -1);
                }).remove();

                checkbox.attr('value', isChecked ? "True" : "False");

                if (isChecked) {
                    checkbox.attr('checked', 'checked');
                    $($t.treeview.getNodeInputsHtml(this.getItemValue($item), this.getItemText($item), arrayName, index))
                        .appendTo($checkboxHolder);
                } else {
                    checkbox[0].removeAttribute('checked');
                }
            }, this));
        },

with this one:

nodeCheck: function (li, isChecked) {
           $(li, this.element).each($.proxy(function (index, item) {
               var $item = $(item).closest('.t-item'),
                   $checkboxHolder = $("> div > .t-checkbox", $item),
                   arrayName = this.element.id + '_checkedNodes',
                   index = $checkboxHolder.find(':input[name="' + arrayName + '.Index"]').val(),
                   checkbox = $checkboxHolder.find(':checkbox');

               $checkboxHolder.find(':hidden').filter(function() {
                   // use filter because of nested square brackets
                   return ($(this).attr("name").indexOf(arrayName + '[' + index + '].') > -1);
               }).remove();

               checkbox.attr('value', isChecked ? "True" : "False");

               if (isChecked) {
                   checkbox.attr('checked', 'checked');
                   $($t.treeview.getNodeInputsHtml(this.getItemValue($item), this.getItemText($item), arrayName, index))
                       .appendTo($checkboxHolder);
               } else {
                   checkbox.attr('checked', false);
               }
           }, this));
       },

It seems that it is not enough to just remove the "checked" attribute but should also set checked property to false.
