I am using control named 'tree' from http://www.jeasyui.com. But in my case I want to load at first highest level then when click to one of node load it's child nodes.
<ul id="tt" checkbox="true" animate="true"></ul>
$(function() {
$('#tt').tree({
data: #Html.Raw(Model.Tree)
});
});
on this function I get childs nodes for selected node from DB:
$(function() {
$('#tt').tree({
onBeforeExpand: function(node) {
var hospitalId = node.id;
$.getJSON('#Url.Action("LoadDepartments")', { hospitalId: hospitalId }, function () {
});
}});});
[HttpGet]
public ActionResult LoadDepartments(Guid hospitalId)
{
LoadHospitals();
var departments = _templateAccessor.GetDepartments(hospitalId);
var hospital = tree.Where(obj => obj.id == hospitalId.ToString()).FirstOrDefault();
if (hospital != null)
{
foreach (var department in departments)
{
DataTreeModel dep = new DataTreeModel();
dep.id = department.Id.ToString();
dep.text = department.Name;
dep.state = "closed";
hospital.children.Add(dep);
hospital.state = "open";
}
}
var result = SerializeToJsonString(tree);
return Json(result, JsonRequestBehavior.AllowGet);
}
In method LoadDepartments I have correct structure but the tree doesn't show new elements. the question is how to clean up previous content of tree and fill it with new content, maybe I am doing something wrong?
jqTree
This Tree should have the features you require, it's very lightweight and easy to use. I'm not advertising but I was in the same situation a couple of weeks ago, and this offered me a solution. It will also keep track of opened up nodes, etc...

I have an async method which calls a mapper for turning HTML string into an IEnumerable:
public async Task<IEnumerable<MovieRatingScrape>> GetMovieRatingsAsync(string username, int page)
{
var response = await _httpClient.GetAsync($"/betyg/{username}?p={page}");
response.EnsureSuccessStatusCode();
var html = await response.Content.ReadAsStringAsync();
return new MovieRatingsHtmlMapper().Map(html);
}
...
public class MovieRatingsHtmlMapper : HtmlMapperBase<IEnumerable<MovieRatingScrape>>
{
// In reality, this method belongs to base class with signature T Map(string html)
public IEnumerable<MovieRatingScrape> Map(string html)
{
var htmlDocument = new HtmlDocument();
htmlDocument.LoadHtml(html);
return Map(htmlDocument);
}
public override IEnumerable<MovieRatingScrape> Map(HtmlDocument item)
{
var movieRatings = new List<MovieRatingScrape>();
var nodes = item.DocumentNode.SelectNodes("//table[#class='list']/tr");
foreach (var node in nodes)
{
var title = node.SelectSingleNode("//td[1]/a")?.InnerText;
movieRatings.Add(new MovieRatingScrape
{
Date = DateTime.Parse(node.SelectSingleNode("//td[2]")?.InnerText),
Slug = node.SelectSingleNode("//td[1]/a[starts-with(#href, '/film/')]")?
.GetAttributeValue("href", null)?
.Replace("/film/", string.Empty),
SwedishTitle = title,
Rating = node.SelectNodes($"//td[3]/i[{XPathHasClass("fa-star")}]").Count
});
}
return movieRatings;
}
}
The resulting list movieRatings contains copies of the same object, but when I look at the HTML and when I debug and view the HtmlNode node they differ as they are supposed to.
Either I'm blind to something really obvious, or I am hitting some async issue which I do not grasp. Any ideas? I should be getting 50 unique objects out of this call, now I am only getting the first 50 times.
Thank you in advance, Viktor.
Edit: Adding some screenshots to show my predicament. Look at locals InnerHtml (node) and title for item 1 and 2 of the foreach loop.

A single xpath is enough.

I'm trying to make an dynamic menu for Dashboards,
I have an register of Dashboards, this will just have an Description and Link.
After register this, it has to appear in menu.
My new menu page will contain an frame to open this link inside the new page.
Has an easy way to alter the menu in serenity to has this behavior?
I have make this altering the NavigationModel.cs
After search alot, don't found any example doing that.
I have create a DynamicNavigation like this:
public class DynamicDashboards : INavigationItemSource
{
public List<NavigationItemAttribute> GetItems()
{
var items = new List<NavigationItemAttribute>
{
new NavigationMenuAttribute(1000, "Dashboards", "icon-speedometer")
};
using (var connection = SqlConnections.NewByKey("Default"))
{
var dashboards = connection.List<DashboardsRow>();
foreach (var dashboard in dashboards)
items.Add(new NavigationLinkAttribute(1000,
path: "Dashboards/" + dashboard.Descricao.Replace("/", "//"),
url: "~/Dashboards/DefaultDashboard?link=" + dashboard.Link,
permission: CadastrosPermissionKeys.General,
icon: "icon-speedometer"));
}
return items;
}
}
Them on NavigationModel.cs, i'm calling this class for insert it on Items
var dy = new DynamicDashboards();
var dashboardMenu = NavigationHelper.ConvertToNavigationItems(NavigationHelper.ByCategory(dy.GetItems()), x => x != null && x.StartsWith("~/") ? VirtualPathUtility.ToAbsolute(x) : x);
Items[0] = dashboardMenu[0]
In my case i have an default menu inside Dashboard, so i just adding this again on position [0], you can manipulate this like you want.
Hello i need your super help.
Im not soo skilled in C# and i stack for about 6 hours on this. So please if anyone know help me . Thx
I have Xml like this
<COREBASE>
<AGENT>
<AGENT_INDEX>1</AGENT_INDEX>
<AGENT_PORTER_INDEX>
</AGENT_PORTER_INDEX>
<AGENT_NAME>John</AGENT_NAME>
<AGENT_SURNAME>Smith</AGENT_SURNAME>
<AGENT_MOBILE_NUMBER>777777777</AGENT_MOBILE_NUMBER>
</AGENT>
<AGENT>
<AGENT_INDEX>2</AGENT_INDEX>
<AGENT_PORTER_INDEX>1
</AGENT_PORTER_INDEX>
<AGENT_NAME>Charles</AGENT_NAME>
<AGENT_SURNAME>Bukowski</AGENT_SURNAME>
<AGENT_MOBILE_NUMBER>99999999</AGENT_MOBILE_NUMBER>
</AGENT>
</COREBASE>
And I need to select agent by index in windows forms combo box and than edit and save his attributes to xml. I found how to edit and save it but i dont know why but its saved to the first agent and overwrite his attributes in XML but not in the selected one.. :-(
Plese i will be glad for any help
private void buttonEditAgent_Click(object sender, EventArgs e)
{
XmlDocument AgentBaseEdit = new XmlDocument();
AgentBaseEdit.Load("AgentBase.xml");
XDocument AgentBase = XDocument.Load("AgentBase.xml");
var all = from a in AgentBase.Descendants("AGENT")
select new
{
agentI = a.Element("AGENT_INDEX").Value,
porterI = a.Element("AGENT_PORTER_INDEX").Value,
agentN = a.Element("AGENT_NAME").Value,
agentS = a.Element("AGENT_SURNAME").Value,
agentM = a.Element("AGENT_MOBILE_NUMBER").Value,
};
foreach (var a in all)
{
if ("" == textBoxEditAgentIndex.Text.ToString())
{
MessageBox.Show("You must fill Agent Index field !!", "WARNING");
}
else
{
// AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_INDEX").InnerText == textBoxEditAgentIndex.Text
if (a.agentI == textBoxEditAgentIndex.Text.ToString())
{
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_INDEX").InnerText = textBoxEditAgentIndex.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_PORTER_INDEX").InnerText = textBoxEditAgentPorterIndex.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_NAME").InnerText = textBoxEditAgentName.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_SURNAME").InnerText = textBoxEditAgentSurname.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_MOBILE_NUMBER").InnerText = textBoxEditAgentMobile.Text;
AgentBaseEdit.Save("AgentBase.xml");
ClearEditAgentTxtBoxes();
}
}
}
}
Am i on the right way but i dont see the doors or i am totaly wrong ? Thx all. Miko
OK i tried it this way but it didnt changed the inner text
string agentIndex = comboBoxEditAgentI.SelectedItem.ToString();
XmlDocument AgentBaseEdit = new XmlDocument();
AgentBaseEdit.Load("AgentBase.xml");
XDocument AgentBase = XDocument.Load("AgentBase.xml");
var xElemAgent = AgentBase.Descendants("AGENT")
.First(a => a.Element("AGENT_INDEX").Value == agentIndex);
xElemAgent.Element("AGENT_MOBILE_NUMBER").Value = textBoxEditAgentMobile.Text;
xElemAgent.Element("AGENT_SURNAME").Value = textBoxEditAgentSurname.Text;
AgentBaseEdit.Save("AgentBase.xml");
It would be easier if you use Linq2Xml.
int agentIndex = 2;
XDocument xDoc = XDocument.Load(filename);
var xElemAgent = xDoc.Descendants("AGENT")
.First(a => a.Element("AGENT_INDEX").Value == agentIndex.ToString());
//or
//var xElemAgent = xDoc.XPathSelectElement(String.Format("//AGENT[AGENT_INDEX='{0}']",agentIndex));
xElemAgent.Element("AGENT_MOBILE_NUMBER").Value = "5555555";
xDoc.Save(fileName)
PS: namespaces: System.Xml.XPath System.Xml.Linq
It does not work, because you are selecting the first agent explicitly with in each loop
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/...")
But you can do it easier by reading and changing withing the same xml document. I'm only changing the agent name and replacing it with "test 1", "test 2", ...
XDocument AgentBase = XDocument.Load("AgentBase.xml");
int i = 0;
foreach (XElement el in AgentBase.Descendants("AGENT")) {
el.Element("AGENT_NAME").Value = "test " + ++i;
// ...
}
AgentBase.Save("AgentBase.xml");
UPDATE
However, I'm suggesting you to separate the logic involving the XML handling from the form. Start by creating an Agent class
public class Agent
{
public string Index { get; set; }
public string PorterIndex { get; set; }
public string Name { get; set; }
public string Surname { get; set; }
public string Mobile { get; set; }
}
Then create an interface defining the needed functionality for an agent repository. The advantage of this interface is that it will make it easier later to switch to another kind of repository like a relational database.
public interface IAgentRepository
{
IList<Agent> LoadAgents();
void Save(IEnumerable<Agent> agents);
}
Then create a class that handles the agents. Here is a suggestion:
public class AgentXmlRepository : IAgentRepository
{
private string _xmlAgentsFile;
public AgentXmlRepository(string xmlAgentsFile)
{
_xmlAgentsFile = xmlAgentsFile;
}
public IList<Agent> LoadAgents()
{
XDocument AgentBase = XDocument.Load(_xmlAgentsFile);
var agents = new List<Agent>();
foreach (XElement el in AgentBase.Descendants("AGENT")) {
var agent = new Agent {
Index = el.Element("AGENT_INDEX").Value,
PorterIndex = el.Element("AGENT_PORTER_INDEX").Value,
Name = el.Element("AGENT_NAME").Value,
Surname = el.Element("AGENT_SURNAME").Value,
Mobile = el.Element("AGENT_MOBILE_NUMBER").Value
};
agents.Add(agent);
}
return agents;
}
public void Save(IEnumerable<Agent> agents)
{
var xDocument = new XDocument(
new XDeclaration("1.0", "utf-8", null),
new XElement("COREBASE",
agents.Select(a =>
new XElement("AGENT",
new XElement("AGENT_INDEX", a.Index),
new XElement("AGENT_PORTER_INDEX", a.PorterIndex),
new XElement("AGENT_NAME", a.Name),
new XElement("AGENT_SURNAME", a.Surname),
new XElement("AGENT_MOBILE_NUMBER", a.Mobile)
)
)
)
);
xDocument.Save(_xmlAgentsFile);
}
}
The form can now concentrate on the editing logic. The form does not even need to know what kind of repository to use if you inject the repository in the form constructor (of cause the form constructor must declare a parameter of type IAgentRepository):
var myAgentForm = new AgentForm(new AgentXmlRepository("AgentBase.xml"));
myAgentForm.Show();
UPDATE #2
Note that you cannot change a single item within an XML file. You must load all the agents, make an edit and then rewrite the whole file, even if you edited only one agent.
To do this, you can use my LoadAgents method, then pick an agent from the returned list, edit the agent and finally write the agents list back to the file with my Save method. You can find an agent in the list with LINQ:
Agent a = agents
.Where(a => a.Index == x)
.FirstOrDefault();
This returns null if an agent with the required index does not exist. Since Agent is a reference type, you don’t have to write it back to the list. The list is keeping a reference to the same agent as the variable a.
I am playing around with a SharePoint server and I am trying to programmatically add a service request to microsoft's call center application template. So far, I have had pretty good success. I can add a call for a specified customer and assign a specific support tech:
private enum FieldNames
{
[EnumExtension.Value("Service Request")]
ServiceRequest,
[EnumExtension.Value("Customer")]
Customer,
[EnumExtension.Value("Service Representative")]
ServiceRepresentative,
[EnumExtension.Value("Assigned To")]
AssignedTo,
[EnumExtension.Value("Software")]
Software,
[EnumExtension.Value("Category")]
Category
}
private void CreateServiceCall(string serviceCallTitle, string customerName, string serviceRep)
{
SPSite allSites = new SPSite(siteURL);
SPWeb site = allSites.AllWebs[siteName];
SPListItemCollection requestsList = site.Lists[serviceRequests].Items;
SPListItem item = requestsList.Add();
SPFieldLookup customerLookup = item.Fields[FieldNames.Customer.Value()] as SPFieldLookup;
item[FieldNames.ServiceRequest.Value()] = serviceCallTitle;
if (customerLookup != null)
{
using (SPWeb lookupWeb = allSites.OpenWeb(customerLookup.LookupWebId))
{
SPList lookupList = lookupWeb.Lists.GetList(new Guid(customerLookup.LookupList), false);
foreach (SPListItem listItem in lookupList.Items)
{
if (listItem[customerLookup.LookupField].ToString() != customerName) continue;
item[FieldNames.Customer.Value()] = new SPFieldLookupValue(listItem.ID, customerName);
break;
}
}
}
SPUserCollection userCollection = site.SiteUsers;
if (userCollection != null)
{
foreach (SPUser user in userCollection)
{
if (user.Name != serviceRep) continue;
item[FieldNames.AssignedTo.Value()] = user;
break;
}
}
item.Update();
site.Close();
allSites.Close();
}
I added two custom columns (category, software) to the default list:
I populated both of these columns inside of SharePoint, now I want to retrieve that data so I can use it in the code snippet I posted to assign the proper category/software etc to the call. I have not been able to get the list in the code, I have tried using a item["Software"], site.Lists["Software"] and a couple of others, but so far all I have come up is null.
Can anyone point me in the right direction for this? Thanks!
SPFieldMultiChoice and related fields have a Choices property:
SPFieldMultiChoice software = item.Fields[FieldNames.Software.Value()] as SPFieldMultiChoice;
StringCollection softwareChoices = software.Choices;
If you need to set a value on the field, use the SPFieldMultiChoiceValue type:
SPFieldMultiChoiceValue values = new SPFieldMultiChoiceValue();
values.Add("Choice 1");
values.Add("Choice 2");
item[FieldNames.Software.Value()] = values;
