Hi everyone again,

How to check SelectedNode's child? There is ->SelectedNode->Parent, but how
to check/control a child?

Thanks in advance,
gmb

'Me.TreeView1.SelectedNode.Nodes(<index>)'.
 
Ty for Your reply,

I would like to control a node only if it has a child node.

if (TreeView1->SelectedNode->Nodes[0])
{
//mycode
}

Given code works (enters parenthesis) only if a node has child nodes, but if
there is no TreeView1->SelectedNode->Nodes[0] it returns an exception of
type System.ArgumentOutOfRangeException.
Could You tell me what should be taken into considerations? I really don't
want to handle this exception.
