I am having a problem with selecting a certain child node.
What I want to achieve: I you have this treeview for example (one parent with two child nodes):
Parent
-Child with a value 5
-Child with a value 2.
I want to add these two values and assign them to Parent node:
Parent result 7
-Child 5
-Child 2.
Of course, a bigger treeview would have several parents and lots of children and they will all add up to one root node.
How can I do this?? pls help.
thx,
Caslav
Dunno if this matches your request, but this will add all childs > parent node
private void button2_Click(object sender, EventArgs e)
{
int grandTotal = CalculateNodes(this.treeView1.Nodes);
}
private int CalculateNodes(TreeNodeCollection nodes)
{
int grandTotal = 0;
foreach (TreeNode node in nodes)
{
if (node.Nodes.Count > 0)
{
int childTotal = CalculateNodes(node.Nodes);
node.Text = childTotal.ToString();
grandTotal += childTotal;
}
else
{
grandTotal += Convert.ToInt32(node.Text);
}
}
return grandTotal;
}
you should do some error checking etc etc to make it solid
