Selecting only parent node?

[V]

After trying for hours to accomplish something that in theory should be a simple task, i've decided to turn to the forums for help!

I have a tree view (with checkboxes) with ONE parent node, and multiple child nodes.

I also have an asp:OptionButtonList, with three options: Full, Partial, and None.

If a user clicks "Full", the Parent node and child nodes should be checked.

If a user clicks "Partial", only the Parent node should be checked...no child nodes.

And, obviously, if a user clicks "None", no nodes should be checked.

I can get the Full and None options to work...but not the partial.

Can anyone help?

So far i'm doing this:

switch (rbl.SelectedValue)
            {
                case "Full":
                    radTreeView.CheckAllNodes();
                    return;
                case "None":
                    isChecked = false;
                    break;
                case "Partial":
                    isChecked = false;
                    break;
                default:
                    break;
            }

            foreach (RadTreeNode node in radTreeView.Nodes)
            {
                node.Checked = isChecked;
            }

obviously this isn't going to accomplish what I want for the "Partial" option, but i've tried what seems like a billion different things, and I can't seem to just check the Parent Node...

Thanks in advance!

Hi V,

Well you can check if a node has children => it's parent node (non-terminal/not a leaf node):

bool isPartial = false;
switch (rbl.SelectedValue)
{
    case "Full":
        radTreeView.CheckAllNodes();
        return;
    case "Partial":
        isPartial = true;
        break;
    default:
        break;
}
var allNodes = radTreeView.GetAllNodes();
foreach (RadTreeNode node in allNodes)
{
    bool isChecked = false;
    if (isPartial)
    {
        if (node.Nodes.Count > 0)
            isChecked = true;
    }
    node.Checked = isChecked;
}

This should work for you!
