Need JavaScript function to clear checkboxes

Hello,

I need to be able to clear out all checkboxes in my treeview via javascript. I tried guessing on what the function might be:

var control = $find('<%=selectuser.ClientID %>');
checkedItems = control.get_checkedNodes();
for (var i = 0; i < checkedItems.length; i++) {
checkedItems[i].set_checkState() = 0;
}

but this didn't work as the items still displayed a check in the checkbox. Can I please be given the syntax to clearing out all checkboxes on clientside?

Thanks.

Hello Shane,

Thank you for posting in the community.

As set_checkState is a function the desired state value should be passed as a parameter to it.

Please note that after unchecking a node, the checked nodes collection of the tree would also be automatically updated. Below is a sample function for deselecting all tree nodes:

Code Snippet

function deselectNodes() {

    var control = $find('<%=WebDataTree1.ClientID %>');

    while (control.get_checkedNodes().length > 0) {

        control.get_checkedNodes()[0].set_checkState(0);

    }

}

Hope this helps.

Hi Peter,

I am trying to set the selected node of webdatatree using javascript. Which is parentnode. It

return with undefined.

Neither TopCurrentNode.get_parentNode().set_selected(true) nor TopRptTree.set_activeNode(TopCurrentNode.get_parentNode()) works

here is the function

function WebTabSelectedIndexChange(sender, e) {

var webTab = ig_controls.ReportTab;

var selectedIndex = webTab.get_selectedIndex();

var selectedTab = webTab.get_tabs()[selectedIndex];

     if (selectedIndex == 0) {

            var TopRptTree = parent.frames[0].$find('TopReportTree');

      var TopCurrentNode = TopRptTree.get_selectedNodes()[0];

                if (TopCurrentNode && TopCurrentNode.get_parentNode()) {

                    TopCurrentNode.get_parentNode().set_selected(true)

                 }

                 }

Thanks

Arshi
