Hi,

If you load nodes on demand in a tree that has ShowCheckBox(true) then the newly loaded nodes aren't rendered with checkboxes. To fix edit telerik.treeview.js:

  1. Line 250, change:

    $t.treeview.getGroupHtml(data, groupHtml,
    this.isAjax(), $item.hasClass('t-treeview'));

    to

    $t.treeview.getGroupHtml(data, groupHtml,
    this.isAjax(), $item.hasClass('t-treeview'), this.showCheckBox);
  2. Line 492, change:

    getGroupHtml:

    function(data, html, isAjax, isFirstLevel) {

     


    to

    getGroupHtml:

    function(data, html, isAjax, isFirstLevel, showCheckBox) {

  3. Line 523, change:

     

    if

     

    (this.ShowCheckBox)

    to

     

    if

     

    (showCheckBox)

     

  4. Line 544, change:

    this

     

    .getGroupHtml(item.Items, html, isAjax, false);

     


    to

    this

     

    .getGroupHtml(item.Items, html, isAjax, false, showCheckBox);


Cheers,

Kev
