C# Treeview nodes help

[gigantour]

Hi Guys

Lets say I have a treeview with parent nodes that have child nodes that have grandchild nodes.

The Question I have is lets say I select a grand child node. . . .How will I detect what that grand child nodes value is and the child and parent value is of the selected grandchild?


Thanks?

Map the NodeClick event of the treeview, when clicked... check the node.text values using Parent and Nodes properties as required to get values up and down the family tree relative to that node...

        private void onNodeClick(object sender, TreeNodeMouseClickEventArgs e)
        {
            string selectedValue = e.Node.Text;  // selected (clicked) node
            string childOfSelectedValue = e.Node.Nodes[0].Text;   // 1st child of selected
            string parentOfSelectedValue = e.Node.Parent.Text;   // parent of selected
        }

If you wanted the grand parent...

e.Node.Parent.Parent.Text;

etc....

Note: You'll want to do some checking of course, to make sure child nodes and parent nodes exist and have values before trying to access them...
