Im trying to use Grid Component. I need to define the order of a column, I'm using this proyect:
https://github.com/vaadin/tutorial/tree/v8-step4
And I add this code:
Column name = grid.addColumn(customer -> customer.getFirstName() + " " + customer.getLastName())
.setCaption("Name")
.setSortOrderProvider(direction -> Stream.of(
new QuerySortOrder("lastName", direction)
));
grid.setSortOrder(GridSortOrder.asc(name));
But I'm not getting the expected results, I'm getting ordered by firstName and then by lastName but i need the results ordered by lastName.
Have you had the same problem? How have you solved it?
Thank you.
I digged into the code and found out that you need you need to call setComparator instead of the setSortOrderProvider. The former is intended for in-memory data providers. Unfortunately, it's a little bit confusing and not really well documented.
I use this implementation of setComparator and it's working. : )
Column name = grid.addColumn(customer -> customer.getFirstName() + " " + customer.getLastName())
.setCaption("Name")
.setComparator(new SerializableComparator<Customer>() {
#Override
public int compare(Customer arg0, Customer arg1) {
return arg0.getLastName().compareTo(arg1.getLastName());
}
});
With Lambda:
.setComparator((customer0, customer1) -> {
return customer0.getLastName().compareTo(customer1.getLastName());
});
and this other option:
Column name = grid.addColumn(customer -> customer.getFirstName() + " " + customer.getLastName())
.setCaption("Name")
.setComparator(grid.getColumn("lastName").getComparator(SortDirection.ASCENDING));
Can any one help me to get full category path from a given keyword. I am giving one example as below,
Example:
Category 1----> Keyword 1 -----> Keyword 11,
say from metadata i got the value "Keyword 11", but i need whole path i.e. /Category 1/ Keyword 1/Keyword 11.
Can anyone help me how to achieve this in Template Building Block using c#.
Maybe you can try and play with one of the following:
keyword.ParentKeywords recursively to create the path you are looking for.
OrganizationalItem oi = keyword.OrganizationalItem; // to get all the organizational items
keyword.OwningRepository
Hope that helps!
Below code should help you to get the path.
bool isRecursive = false;
KeywordField kwdField = (KeywordField)metaFields["kwdField"];
Keyword curKwd = new Keyword(kwdField.Value.Id, engine.GetSession());
string kwdPath = curKwd.Title;
while (!isRecursive) {
if (curKwd.ParentKeywords.Count > 0){
foreach (Keyword kwd in curKwd.ParentKeywords) {
kwdPath = kwd.Title + "/" + kwdPath;
}
curKwd = curKwd.ParentKeywords[0];
} else {
isRecursive = true;
}
}
kwdPath = curKwd.OrganizationalItem.Title + "/" + kwdPath;
I'm trying to implement this solution to "grey out" past events in Fullcalendar, but I'm not having any luck. I'm not too well versed in Javascript, though, so I assume I'm making some dumb mistakes.
I've been putting the suggested code into fullcalendar.js, inside the call for daySegHTML(segs) around line 4587.
I added the first two lines at the end of the function's initial var list (Why not, I figured)—so something like this:
...
var leftCol;
var rightCol;
var left;
var right;
var skinCss;
var hoy = new Date;// get today's date
hoy = parseInt((hoy.getTime()) / 1000); //get today date in unix
var html = '';
...
Then, just below, I added the other two lines inside the loop:
for (i=0; i<segCnt; i++) {
seg = segs[i];
event = seg.event;
classes = ['fc-event', 'fc-event-skin', 'fc-event-hori'];
if (isEventDraggable(event)) {
classes.push('fc-event-draggable');
}
unixevent = parseInt((event.end.getTime()) / 1000); //event date in Unix
if (unixevent < hoy) {classes.push('fc-past');} //add class if event is old
if (rtl) {
if (seg.isStart) {
classes.push('fc-corner-right');
}
...
Running this code results in a rendered calendar with no events displayed and an error message: Uncaught TypeError: Cannot call method 'getTime' of null
The "null" being referred to is, apparently, event.end.getTime(). But I'm not sure I understand what exactly is going wrong, or how things are being executed. As written, it seems like it should work. At this point in the code, from what I can tell, event.end contains a valid IETF timecode, but for some reason it's "not there" when I try to run it through getTime()?
This isn't a mission-critical tweak for me, but would still be nice—and I'd like to understand what's going on and what I'm doing wrong, as well! Any help greatly appreciated!
If you are using FullCalendar2 with Google Calendar, you will need to use the version of the code below. This uses Moment.js to do some conversions, but since FC2 requires it, you'll be using it already.
eventRender: function(event, element, view) {
var ntoday = new Date().getTime();
var eventEnd = moment( event.end ).valueOf();
var eventStart = moment( event.start ).valueOf();
if (!event.end){
if (eventStart < ntoday){
element.addClass("past-event");
element.children().addClass("past-event");
}
} else {
if (eventEnd < ntoday){
element.addClass("past-event");
element.children().addClass("past-event");
}
}
}
As per FullCalendar v1.6.4
Style past events in css:
.fc-past{background-color:red;}
Style future events in css:
.fc-future{background-color:red;}
There's no need to fiddle with fullcalendar.js. Just add a callback, like:
eventRender: function(calev, elt, view) {
if (calev.end.getTime() < sometime())
elt.addClass("greyclass");
},
you just have to define the correct CSS for .greyclass.
Every event has an ID associated with it. It is a good idea to maintain your own meta information on all events based on their ids. If you are getting the events popupated from a backend database, add a field to your table. What has worked best for me is to rely on callbacks only to get the event ids and then set/reset attributes fetched from my own data store. Just to give you some perspective, I am pasting below a section of my code snippet. The key is to target the EventDAO class for all your needs.
public class EventDAO
{
//change the connection string as per your database connection.
//private static string connectionString = "Data Source=ASHIT\\SQLEXPRESS;Initial Catalog=amit;Integrated Security=True";
//this method retrieves all events within range start-end
public static List<CalendarEvent> getEvents(DateTime start, DateTime end, long nParlorID)
{
List<CalendarEvent> events = new List<CalendarEvent>();
// your data access class instance
clsAppointments objAppts = new clsAppointments();
DataTable dt = objAppts.SelectAll( start, end);
for(int i=0; i<dt.Rows.Count; ++i)
{
CalendarEvent cevent = new CalendarEvent();
cevent.id = (int)Convert.ToInt64(dt.Rows[i]["ID"]);
.....
Int32 apptDuration = objAppts.GetDuration(); // minutes
string staffName = objAppts.GetStaffName();
string eventDesc = objAppts.GetServiceName();
cevent.title = eventDesc + ":" + staffName;
cevent.description = "Staff name: " + staffName + ", Description: " + eventDesc;
cevent.start = (DateTime)dt.Rows[i]["AppointmentDate"];
cevent.end = (DateTime) cevent.start.AddMinutes(apptDuration);
// set appropriate classNames based on whatever parameters you have.
if (cevent.start < DateTime.Now)
{
cevent.className = "pastEventsClass";
}
.....
events.Add(cevent);
}
}
}
The high level steps are as follows:
Add a property to your cevent class. Call it className or anything else you desire.
Fill it out in EventDAO class while getting all events. Use database or any other local store you maintain to get the meta information.
In your jsonresponse.ashx, retrieve the className and add it to the event returned.
Example snippet from jsonresponse.ashx:
return "{" +
"id: '" + cevent.id + "'," +
"title: '" + HttpContext.Current.Server.HtmlEncode(cevent.title) + "'," +
"start: " + ConvertToTimestamp(cevent.start).ToString() + "," +
"end: " + ConvertToTimestamp(cevent.end).ToString() + "," +
"allDay:" + allDay + "," +
"className: '" + cevent.className + "'," +
"description: '" +
HttpContext.Current.Server.HtmlEncode(cevent.description) + "'" + "},";
Adapted from #MaxD The below code is what i used for colouring past events grey.
JS for fullcalendar pulling in Json
events: '/json-feed.php',
eventRender: function(event,element,view) {
if (event.end < new Date().getTime())
element.addClass("past-event");
},
other options ....
'event.end' in my Json is a full date time '2017-10-10 10:00:00'
CSS
.past-event.fc-event, .past-event .fc-event-dot {
background: #a7a7a7;
border-color: #848484
}
eventDataTransform = (eventData) => {
let newDate = new Date();
if(new Date(newDate.setHours(0, 0, 0, 0)).getTime() > eventData.start.getTime()){
eventData.color = "grey";
}else{
eventData.color = "blue";
}
return eventData;
}
//color will change background color of event
//textColor to change the text color
Adapted from #Jeff original answer just simply check to see if an end date exists, if it does use it otherwise use the start date. There is an allDay key (true/false) but non allDay events can still be created without an end date so it will still throw an null error. Below code has worked for me.
eventRender: function(calev, elt, view) {
var ntoday = new Date().getTime();
if (!calev.end){
if (calev.start.getTime() < ntoday){
elt.addClass("past");
elt.children().addClass("past");
}
} else {
if (calev.end.getTime() < ntoday){
elt.addClass("past");
elt.children().addClass("past");
}
}
}
Ok, so here's what I've got now, that's working (kind of):
eventRender: function(calev, elt, view) {
var ntoday = new Date();
if (calev.start.getTime() < ntoday.getTime()){
elt.addClass("past");
elt.children().addClass("past");
}
}
In my stylesheet, I found I needed to restyle the outer and inner elements to change the color; thus the elt.children().addclass addition.
The only time check I could get to work, lacking an end time for all day events, was to look at the start time - but this is going to cause problems with multi-day events, obviously.
Is there another possible solution?
This query will take input from three drop down box and a text box and it work's fine as expected.But my requirement is i need to use another three drop down box and a text in order to query much deeper.So,i need to hold the result of first query and also second query.How should i do.Help me.
That another three drop down box value is also obtained from the same variable's as 'operator','textvalue','querypass'.
function querymap()
{
var operator=document.getElementById('operatorstring').value.replace(/'/g, "\\'");
var textvalue=document.getElementById("text-value").value.replace(/'/g, "\\'");
var querypass=document.getElementById('query-pass').value.replace(/'/g, "\\'");
var searchStringe = document.getElementById('Search-stringe').value.replace(/'/g, "\\'");
var searchString = document.getElementById('search-string').value.replace(/'/g, "\\'");
{
layer.setQuery("SELECT 'geometry'," + querypass + " FROM " + tableid + " WHERE " + querypass + " " + operator + " '" + textvalue + "' AND VillageName = '"+ searchStringe+"'");
}
}
You can have as many AND conditions in your query as you want. No reason not to also check e.g. textvalue2, querypass2, searchString2, etc. and add them to your query. See this setQuery() answer which may give you some ideas. You'll need to set all your search conditions each time you call layer.setQuery() or layer.setOptions({query: ...});
i have this code
MasterSoapClient sp = new MasterSoapClient();
MasterData[] lstMasterData = sp.GetActivityType(stid, null, 1);
grdEditActivityType.DataSource = lstMasterData;
grdEditActivityType.DataBind();
Session["opType"] = 2;
txtActivityCode.Text = lstMasterData.ToString();
txtActivityCode.DataBind();
here i called web service and put all data in this Gridview "grdEditActivityType "
and already workin
but there is column of lstMasterData i want to put it in the text box out of the grid
how i can do this ?
txtActivityCode.Text is a Property that you can use to assign a text value to the TextBox.
If you use txtActivity.Text = " some input "; Your textbox will contain the text " some input ".
You don't need to Bind txtActivityCode afterwards.
Having this clarified the next step is to create the string you want using to assign to the text box.
string s = "";
foreach( var masterData in lstMasterData )
{
s += masterData.SomeProperty; // s += masterData.ToString(); maybe, it depends on what do you want to put in the textbox;
}
txtActivityCode.Text = s;
And that's all.
I would suggest to start look more over ASP.NET tutorials to understand better how this framework works.
