how to extend asp.net application in this scenario - javascript

I have asp.net web application.where i am creating the User as registration for a particular Firm.In this firm there are 3 type of user as of now. as Admin, Dealer, Manager. so according to this I am changing the UI page.
Means When Admin (Admin is default entry) going create let say Dealer, then there is different UI except General information fields (like name ,contact details and all). and when creating the manager there is different UI fields, except than General information fields.
To reuse the page i am using this way , when selected Manager then related his UI fields get only visible, same for dealer. obviously there is a dropdown control from where i am selecting User type.
But some how , later on if one more User type get added by firm, I need to generate functionality according to New User type. how can i handle if I don not want to change existing code. sense is how can i write the generic code so that I should not need to change in code behind or in javascript again.
Where as all this things are in planning and under implementation for now. but before to go a head I must clear this thing. I am planning to change the UI structure in javascript as usual way , i means
if selected User Type is "Dealer then make visible these div's ELSE If User Type is Manager then make visible these divs
I want to write generic javacript , though new user type get added.

You could maintain the field <-> user type relation in a database and dynamically add labels and textboxes in the PageLoad of your Page.
Then when a new type of user comes along you'd simply need to add to your data.
Your user type should also be in a database.
Of course, the code that lets your users create other users would also have to be flexible enough. So you'd need a CanCreate table that dictates who can create what type of user. :)
EDIT Expanded how to build your Content
Actually, I like your idea about storing the html elements in the database. That'd save you using reflection to dynamically get the propertyvalue. However, I don't think you'll be able to use databinding and all that.
So instead I'd do something like this:
public enum ControlType
{
Label,
TextBox,
...
}
Make a table something like
UserType
PropertyName
PropertyLabelName
FieldLabelType (int)
FieldContentType (int)
Then on pageload you get the UserType, pull the data from the table, find the div where you want to put the data and then add the controls like:
(pseudocode)
Control label = null;
switch (FieldLabelType)
{
case ControlType.Label:
var label = new Label()
{
.. all kinds of properties
Text = PropertyLabelName
};
control = label;
break;
case ???
...
}
if (label != null)
fielddiv.Add(label);
Control field = null;
switch (FieldContentType)
{
case ControlType.TextBox:
var textbox = new TextBox()
{
.. all kinds of properties
Text = new Binding( ... Path = PropertyName)
};
control = textbox;
break;
case ???
}
if (field != null)
fielddiv.Add(field);
Of course, you'd need to do some positioning to get it all looking pretty. Perhaps chuck in a table or something in code?

An Alternative to Data Attribute in Jquery

i have a webpage where user can select one of different packages to buy from a list. Package details are coming from a database.
HTML Code
<div data-package='2346343' class="retail-package">Cost : 10$</div>
<div data-package='5465654' class="retail-package">Cost : 20$</div>
<div data-package='3455675' class="retail-package">Cost : 30$</div>
Jquery Code
$('.retail-package').on('click', function() {
$(this).addClass("selected-package");
var selectedPackage = $(this).data("package");
});
Now above code shows how we(specially i) normally select a particular thing out of a list when clicked, In this procedure, as you can see in HTML Code, i am giving out or showing the pakcageId to users i.e. anyone can do a inspect element in a browser and view or even manipulate the data-package attribute, for safety i do a server side check of selected data.
My Question
Is there a way to hide this data exposure, or is there any other cleaner way to accomplish this, because i have seen people using Angular, Webpack etc able to implement a list selection without giving out or showing any data which can be seen by inspect element feature in a browser.
Note : i am sorry if my question is too basic, if this cannot done using jquery what are other technologies which i can use ?
You may create a Map where keys are arbitrary, auto-incremented identifiers, and values are package numbers:
const idPackageMap = new Map()
// id generator: whenever you call it, "i" is incremented and returned
const id = (() => {
let i = 0
return () => ++i
})()
const addPackage = package =>
idPackageMap.set(id(), package)
addPackage(2346343)
addPackage(5465654)
addPackage(3455675)
console.log('contents: ', [...idPackageMap.entries()])
console.log('package number for id 2: ', idPackageMap.get(2))
Now, when you insert those <div> elements you may set the arbitrary identifier, and when you need to locate the actual package number is just about using Map#get: idPackageMap.get(1) (change 1 with any arbitrary identifier).

How to make selection on drop down list (DynamicForm) using JavaScript in SmartClient?

Here is a drop down list in SmartClient: http://www.smartclient.com/#dropdownGrid.
I want to make a selection using JavaScript. Like, I run some JavaScript in console, and the drop list will select a specific item.
I did some research, found a code snap to do this (the code is in Java, but I think there should be similar functions in JavaScript):
Record rec = perdomainGrid.getRecordList().find("domaine_id", domaine_id);
perdomainGrid.selectSingleRecord(rec);
If I want to make selection, first I need to obtain perdomainGrid object. In my above giving link, the drop down list id in GWT is exampleForm (can be seen in dropDownGrid.js tab). I try to get the object by:
var form = isc.DynamicForm.getById("exampleForm");
form does exist, but there is no getRecordList() function on it, there is selectSingleRecord() function on it though.
I try to check form's class by form.className, its value is normal. I don't know what does that mean.
I'm kind of confused now. Could somebody help me on this?
isc_SelectItem_5 has a function called pickValue(), it takes one parameter SKU. This function can be used to select item.
var itemName = "Letter Tray Front Load Tenex 200 Class Blk #23001";
var data = isc_SelectItem_5.optionDataSource.cacheData;
var targetSKU = data.find(function(e) {
if (e.itemName == itemName) {
return e;
}
}).SKU;
isc_SelectItem_5.pickValue(targetSKU);

iBooks Author/iAd Producer Widget User Text Disappears

I'm using iAd producer to create HTML widgets for iBooks I'm making using iBooks Author. I've done some research and learned that I can have user input saved into local storage by way of a variable that is called every time the widget is opened. This is great except for the new problem of having to create hundreds of text box widgets all with different variables so I can use these text boxes on multiple pages. Is there a way for me to automate this using Java Script? One idea I had was to use a "while" function to tell the script to ++ the variable if the one it tried to use was not empty. Example: the variable "001" was already used so the code would ideally set the next user text to variable "002". Preferably, I'd like to be able to create one widget with this code that I could reuse anywhere else.
Here is the code I'm currently using:
/*Widget code*/
this.onViewControllerViewWillAppear = function (event) {
var theValue = this.outlets.textField;
if (localStorage.getItem("theKey102") === null) {
theValue.value = "";
} else {
theValue.value = localStorage.getItem("theKey102");
}
};
/*This is the code for one of the text boxes I'm using */
this.onControlValueChange = function (event) {
var theValue = this.viewController.outlets.textField;
localStorage.setItem("theKey102", theValue.value);
};

Task "Regarding" field not populating from subgrid in CRM 2013

I am using CRM 2013 on-premise with UR1 installed
I have a custom entity with a subgrid on it looking at related "tasks" which looks like this:
Whenever I create a task from the subgrid using the "+" button in the top right hand corner of the subgrid; the "Regarding" field of the newly created task remains blank. When it should be populated by a lookup to the record it was created from.
I have javascript on the task entity which checks the "Regarding" field to check what kind of entity it was created from (if it was created from one) and gets certain field values from the calling entity to populate fields on the task.
Since the "Regarding" field is never filled the Javascript never fires - and the fields do not populate.
When the record is saved, if the regarding field is blank (I have not manually filled it in) - it will eventually be populated by the correct record about 10 - 15 seconds later if you refresh the page. Then the correct fields will be populated and the user is able to edit the option set values and save again. This is not ideal for the user as they would like it to be one fluid action.
Is there any way around this problem?
EDIT for future browsers of this question:
Found a partial work around. If you use an "Activity" subgrid rather than a "Task" subgrid the field will populate. This has a drawback though as you cannot edit the "Activity" subgrid's view to show "Task" specific fields.
Ran into this same issue. The way I got around it was to add a look-up to the custom entity on the form (we put this on a hidden tab). When the Task gets created from the custom entity the look-up will be populated. You can then use that look-up to grab the values that you need to populate, including the regarding field. Not the most elegant, but it works.
I also ran into this problem and went with a pure JS approach to resolving. On load of the task form, call populateRegarding().
This works because even though the regarding lookup doesn't populate by default, the query string parameters include _CreateFromType and _CreateFromId values.
This works in 2015, didn't test on earlier versions. Note that it is unsupported.
function populateRegarding() {
var regarding = Xrm.Page.getAttribute("regardingobjectid"),
createFromType = Xrm.Page.context.getQueryStringParameters()._CreateFromType,
createFromId = Xrm.Page.context.getQueryStringParameters()._CreateFromId;
if (!createFromId || !createFromType ||
!regarding || regarding.getValue() !== null) {
return;
}
var entityLogicalName = getEntityLogicalNameFromObjectTypeCode(createFromType);
regarding.setValue([{
id: createFromId,
entityType: entityLogicalName,
name: "Hardcoded Name" // TODO: retrieve name dynamically
}]);
}
// This method uses an undocumented object and is therefore unsupported.
// You could implement a supported version of this function by querying for
// metadata, but that would be very expensive.
function getEntityLogicalNameFromObjectTypeCode(otc) {
var map = Mscrm.EntityPropUtil.EntityTypeName2CodeMap,
logicalName;
otc = Number(otc); // convert string to number
for (logicalName in map) {
if (!map.hasOwnProperty(logicalName)) { continue; }
if (map[logicalName] === otc) {
return logicalName;
}
}
}

Drag and drop ordering of formset with extra entries

I have been looking for a way to allow the user to easily change the order of entries in a formset. I found a StackOverflow question that addresses this subject, with the accepted answer referencing a Django Snippet that uses a JQuery tool to allow drag 'n drop of the entries. This is nifty and cool, but I have a problem with 'extra' entries. If an 'extra' entry is modified and then dragged I get an error on the submit:
(1048, "Column 'order' cannot be null")
I believe Django keeps the 'extra' entries separate, since they have to be inserted instead of updates. So the reordering probably confuses matters. Is there a way to make this work, or are there other suggestions for reordering and/or adding new entries?
Edit: Added some relevant code excerpts. I'm trying this out in the admin, as the snippet shows. I'd like to put it in my own page ultimately, however.
models.py:
class Section(models.Model):
section_id = models.AutoField(primary_key=True)
section_name = models.CharField(max_length=135)
score_order = models.IntegerField()
def __unicode__(self):
return self.section_name
class Meta:
db_table = u'section'
ordering = [u"score_order"]
class Chair(models.Model):
chair_id = models.AutoField(primary_key=True)
member = models.ForeignKey(Member, null=True, blank=True,
limit_choices_to={'current_member': True})
section = models.ForeignKey(Section)
description = models.CharField(max_length=135)
order = models.IntegerField(blank=True, null=True)
def __unicode__(self):
return "%s - %s" % (self.description, self.member)
class Meta:
db_table = u'chair'
ordering = (u'section', u'order')
admin.py
class SectionForm(forms.ModelForm):
model = Section
class Media:
js = (
'/scripts/jquery.js',
'/scripts/ui.core.js',
'/scripts/ui.sortable.js',
'/scripts/section-sort.js',
)
class ChairInline(admin.StackedInline):
model = Chair
admin.site.register(Section,
inlines = [ChairInline],
form = SectionForm,
)
I found my own solution. The snippet was setting the order for every row that had a non-empty primary key value. But the extra rows have an empty primary key, and I believe they have to stay empty for Django to know that they are to be inserted instead of updated. I modified the function to check for the other fields being empty (fortunately, I only have a couple) as well as the primary key:
jQuery(function($) {
$('div.inline-group').sortable({
items: 'div.inline-related',
handle: 'h3:first',
update: function() {
$(this).find('div.inline-related').each(function(i) {
if ($(this).find('input[id$=chair_id]').val() ||
$(this).find('select[id$=member]').val() ||
$(this).find('select[id$=description]').val()) {
$(this).find('input[id$=order]').val(i+1);
}
});
}
});
$('div.inline-related h3').css('cursor', 'move');
$('div.inline-related').find('input[id$=order]').parent('div').hide();
});
This did the trick for me. I could maybe improve it by adding a hidden field to the form that gets set whenever any field on a row gets modified. But at this point I'm still a jQuery n00b, so this will do. If anybody has better ideas, feel free to comment or add another answer.
I do sortable formsets in one of my apps. I use this jQuery drag and drop plugin:
http://www.isocra.com/2008/02/table-drag-and-drop-jquery-plugin/
I bind the plugin's onDrop event to a function that resets the value of all "order" fields.
Additionally, I pass initial data to the formset so the formset's extra "order" fields always have a value in cases where there is no javascript available - the user won't be able to re-order rows, but they can edit and post changes without the null error you described.
