How to save only childnode.

[Tuong Lan (FIS Soft)]

I have a treeview (see attach file )
I want to save four nodes like circle.
I only save success node: Community. I cann't save three nodes: Development, Product, Operation.
Here is code to save:

List<RadTreeNode> checkedNodes = this.trvHierarchy.CheckedNodes.ToList<RadTreeNode>();

                 

List<string> lstJobNode = new List<string>();

 foreach (RadTreeNode node in checkedNodes)

 {

       if (string.IsNullOrEmpty(node.Value) == false

       && node.CheckState == TreeNodeCheckState.Checked)

        {

                 RadTreeNode parentNode = node.ParentNode;
//Only save parent. Don not save child if parent is checked.


                 if (parentNode == null || parentNode.CheckState != TreeNodeCheckState.Checked)

                                lstJobNode.Add(node.Value);

        }

}

Hi Tuong Lan (FIS Soft),

Please make sure that the logic in the code behind that you have pasted is what you need to achieve. As I see, you intend to save only parent nodes whose checkboxes are checked.

if (string.IsNullOrEmpty(node.Value) == false

       && node.CheckState == TreeNodeCheckState.Checked)

However, in the screenshot that you attached, the items that you intended to save are not checked, therefore you are not able to save them. Try to check them (the parent nodes) and see if this works.
