ASPxClientTreeViewNode.SetChecked(value) Method

Sets a value indicating whether the node is checked.

#Declaration

TypeScript
SetChecked(
    value: boolean
): void

#Parameters

Name Type Description
value boolean

true if the node is checked; otherwise, false.

#Remarks

The ASPxTreeView allows end-users to check nodes. Use the SetChecked method to check nodes on the client side via code.

In order to determine whether a node is checked, use the ASPxClientTreeViewNode.GetChecked method on the client side.

To learn more, see the Check Box Support topic.

#Example

The function below checks all nodes within the ASPxTreeView control on the client side.

    function CheckAll(s, e) {
        CheckBranch (treeview);
        function CheckBranch (branch){
            for (var i=0; i < branch.GetNodeCount(); i++){
                branch.GetNode(i).SetChecked(true);
                if (branch.GetNode(i).GetNodeCount() != 0){
                    CheckBranch(branch.GetNode(i));
                }    
            }   
        }
    }
