How can Save Tree view Checked and Uncheked node data in database

Hi,

for Checked nodes do it like:

SqlConnection conn = new SqlConnection(strConnString);
con.Open(); 
foreach (TreeNode item in this.TreeView1.CheckedNodes)
{               
    string query = "INSERT INTO TableName VALUES ('" + item.Text + "')";
    SqlCommand cmd = new SqlCommand(query, conn);
    cmd.ExecuteNonQuery();
}
con.Close();
