transfer data to xml if node is selected
hello ,
I m working on an XML file and treeview :
I want to write a new XML file from a data in a tree view , am doing it with this function and it's seems ok :
private StreamWriter sr;
public void exportToXml(TreeView tv, string filename)
{
sr =
new StreamWriter(filename, false, System.Text.Encoding.UTF8);
//Write the header
sr.WriteLine(
"<?xml version=\"1.0\" encoding=\"utf-8\" ?>");
//Write our root node
sr.WriteLine("<" + treeView1.Nodes[0].Text + ">");
foreach (TreeNode node in tv.Nodes)
{
saveNode(node.Nodes);
}
//Close the root node
sr.WriteLine("</" + treeView1.Nodes[0].Text + ">");
sr.Close();
}
private void saveNode(TreeNodeCollection tnc)
{
foreach (TreeNode node in tnc)
{
if (node.Nodes.Count > 0)
{
sr.WriteLine("<" + node.Text + ">");
saveNode(node.Nodes);
//sr.WriteLine("<" + node.Text + ">");
sr.WriteLine("<" + node.Name + ">");
}
else //No child nodes, so we just write the text
sr.WriteLine(node.Text);
}
}
then fonr the button :
private void button8_Click_1(object sender, EventArgs e)
{
exportToXml(treeView1, @"C:\Users\\Documents\projet\EEE.XML");
}
I want to know if it's possible to transfer in this XML file only data in node selected/cheked in my treeView ?
When my node ( or some nodes ) is selected , then in my xml file i find only this one with the same structure .
Am starter, i dont know how to use event , then if i need event to do this or not ...
