ASPxClientTreeViewNode.GetChecked Method

Returns a value indicating whether the node is checked.

#Declaration

TypeScript
GetChecked(): boolean

#Returns

Type Description
boolean

true if the node is checked; otherwise, false.

#Remarks

The ASPxTreeView allows end-users to check nodes. To determine whether the node is checked, use the GetChecked method on the client side. In order to check/uncheck a specific node on the client side, use the ASPxTreeView’s ASPxClientTreeViewNode.SetChecked method.

To learn more, see the Check Box Support topic.

#Example

The code below lists checked nodes and shows them in a label on the client side.

<script type="text/javascript">
    function OnCheckedChanged(s, e) {
        label.SetText("Checked nodes:");
        ListCheckedNodes(s);
    }

    function ListCheckedNodes(parent){    
        for (var i=0; i < parent.GetNodeCount(); i++){
            if (parent.GetNode(i).GetChecked()){
               label.SetText(label.GetText() + " " + parent.GetNode(i).GetText());    
            }
            if (parent.GetNode(i).GetNodeCount() != 0){
               ListCheckedNodes(parent.GetNode(i));
            }
        }
    }
