Friends.

I'm studying the treeView component and I'm having trouble adding a child node to a selected parent node via programming. The parent node is selected by the checkbox next to the name.

With the line below I add it, but inside the parentheses where there is zero I need to put the selected node and I am not succeeding.

The name of the child node is typed into a textBox2.

treeView1->Nodes[0]->Nodes->Add(textBox2->Text);

Tks.

    You should be able to use SelectedNode directly - no need to index into the collection. Something like this:
    treeView1->SelectedNode->Nodes->Add(...)

    Hi Davi,

    I used this method inside the parentheses instead of zero, by logic that would be it, but it didn't work.

    treeView1->Nodes[treeView1->SelectedNode]->Nodes->Add(textBox2->Text);

    Thank you for the contact.
