I want to delete child node that is selected in comboBox.
private void AccountsSetup_Load(object sender, EventArgs e)
{
// Populating parent nodes with the items in Bank ComboBox that is First.
string[] items = new string[BankList.Items.Count];
for (int i = 0; i < BankList.Items.Count; i++)
{
items[i] = BankList.Items[i].ToString();
//node.Nodes.Add(items[i]);
treeView1.Nodes.Add(items[i]);
}
}
Despite of writing find node which is in Accounts comboBox, it does not find and obviously does not delete.
// If the Account No matches to Account node, it should delete.
TreeNode[] nodes = treeView1.Nodes.Find(AccountsComboBox2.Text, true);
foreach (TreeNode oldnode in nodes)
{
treeView1.Nodes.Remove(oldnode);
}
My add account code, maybe i am doing something wrong here:
treeView1.Nodes[BankList.SelectedIndex].Nodes.Add(AccountNotextBox1.Text);
treeView1.ExpandAll();
the added account goes to AccountComboBox2.
so then I select AccountComboBox2.Text and matches if the node exist in treeview then delete it.
Try add Cast<TreeNode>
and use Where
like this.But first add Tag when you create new node.
First edit your function which add new node
TreeNode newNode = new TreeNode(AccountNotextBox1.Text);
//this is tag
newNode.Tag = AccountsComboBox2.Text;
treeView1.Nodes[BankList.SelectedIndex].Nodes.Add(newNode);
And next find node by Tag
TreeNode[] treeNodes = treeView1.Nodes
.Cast<TreeNode>()
.Where(r => r.Tag == AccountsComboBox2.Text)
.ToArray();
foreach (TreeNode oldnode in treeNodes)
{
if (oldnode.Parent == null)
{
treeView1.Nodes.Remove(oldnode);
}
else
{
oldnode.Parent.Nodes.Remove(oldnode);
}
}
