With the jQuery autocomplete, there are properties I can set to only initiate populating the list when a specific number of characters are typed by the user. This helps to reduce the number of items in the list, when ServerFiltering is enabled.
https://docs.telerik.com/aspnet-mvc/helpers/autocomplete/overview
eg.
.Filter("startswith")
.MinLength(3)
However, I don't see anything similar in the Angular component, unless I'm missing something. There is the filterchange event
https://www.telerik.com/kendo-angular-ui/components/dropdowns/autocomplete/filtering/
This assumes that the list has already been populated and data binding has occurred, so that the list can be filtered.
How can I only bind the list when some minimum number of characters has been typed, as in the case with the jQuery widget using ServerBinding?
You can initially data-bind the AutoComplete to an empty array or a collection of preset initial data items, and call the data service to obtain data from the server only after the user has typed a certain number of characters, e.g.:
DOCS

I'm working on a GUI based on wxpython and have the following question regarding wx.Combobox feature:
Is it possible to display dict.values() in the drop down list and select one of the displayed item but in Bind event send dict.key for this item somehow? I want to present possible options for selection in a user friendly way - example is below.
I think it should be possible with the dictionary but don't know how to realize that.
I'm parsing all Sections from INI file with configparser to a list:
sections= ['123ABC456','123DEF456','123GHI456','123JKL456','123MNO456']
and assign it to Combobox:
self.combo_sections = wx.ComboBox(panel, choices=sections)
self.combo_sections.Bind(wx.EVT_COMBOBOX, self.on_combo_sections)
self.on_combo_sections function is parsing section's options.
What i need is to convert list items to a readable format:
['ABC','DEF','GHI','JKL','MNO']
And display these values under combobox drop down list. Since initial Section's values are essential for further work - based on section name, configparser gets section's options, how can i send original values instead of formatted ones but still display formatted ones under the drop down?
Thanks in advance for any inputs!
wxComboBox supports associating the so called "client data" with each of its items, so you can use this and store the sections value as this client data, then you will be able to get them back whenever you have an index of combobox item.
Alternatively, just keep your own array in combobox items order and store the sections in it -- this is more or less how "client data" is implemented internally anyhow.
The main advantage of using built-in client data support is that it is kept in sync even if the items are added/inserted/deleted to/from the control, but if your combobox doesn't change after creation, using your own data structure should be simpler.
A user of one of my applications has observed a strange behaviour of the selectOneMenu of Primefaces when using filters.
I have a mask with some fields, some of them are selectOneMenues. I deliver values via a map of Strings and use a filter on them, so the user can search for specific values, in this case currencies.
I have set a default value for this field (as the value in the object behind this field).
So, imagine the following case:
User opens the mask - default value is set on the selectOneMenues
User klicks the arrow on the field and opens the list of available values
he types in some characters and a result is returned (he finds various values with it)
when this happens, in the field, the first value from the result list is set automatically
when the user now selects a random entry, it is set and everything is fine
if the user instead decides he want's the default value back he could either click somewhere on the mask and the value is resetted -> works fine
or he could decide to click on the original value, which was set as default before, in this case the selected value doesn't change but stays the first result from the filter
when now saving the entity behind the form, the original default value is saved
I assume that this happens because when the first result from the filter is set, it just set in the frontend and not in the entity behind the form/ the backend.
Is this a known bug? Do you have any idea how to fix it with a reasonable amount of effort?
I will try to convince my customer to accept this behavior, but I think it's a bit strange, although I admit this is a scenario that's not likely to happen, often. Nevertheless, they found it =)
I am using Primefaces version 5.3.11 (elite version or something like that)
I'm trying to read the contents of a "list view" using automation. The first time I navigate to it, I'm able to go from item to item, getting the correct text for each list item. However, when I display a different screen (which is apparently reusing this display object), the text on the screen is different, but automation gets the same text as the first set. From then on I can only get the text for the first view I looked at. It's like the text is being cached and I'm only able to look at the cached view. UISpy, however, seems to grab the right values every time, and if I use it while my automation is paused, I end up getting the right values.
In my automation, I use Find to grab the header, and walk the tree to the List View and get the text for each element. I thought if you used the Current property, you got the live data. Apparently I was mistaken. How do I either refresh the tree or get the REAL data?
Yes, the Current property on a certain AutomationElement will return its current, 'live', value. UIA will not cache anything automatically, you'll have to declare it yourself and explicitly access the Cached properties.
What's probably happening is that the new tree items you're seeing after selecting a different screen, are actually re-created (and that actually makes sense, UI-wise), not just updated. You could easily determine if this is the problem by selecting the first screen and writing down the tree items' RuntimeId property (you can see it in UI Spy). Then, select the second screen and check if the RuntimeId has changed. If it has, then it's just not the same object instance.
If this is the case, all you need to do is get the items again. It'll be easier to do this using AutomationElement.FindAll with a ClassName property condition.
I'm creating a student assignment submission application using xpages (8.5.3 FP3 UP1). The details are:
Student can do any number of submission. For each submission, a unique SubmitID will be created. For now,
a. The Form (Submit) - 2 fields only (SubmitID, SoftCopy-RTF type)
b. The View (Submit) - 2 column only (SubmitID, AttachmentNames)
c. Examples of SubmitID are: submit1, submit2
For each submission, student must select what course/subject that submission is for (eg: Maths, Physics etc). Therefore I've already created another form for the teacher to create the list of subject
a. The Form (Subject) - 1 field only (SubjectName)
b. The View (Subject) - 1 column only (SubjectName)
c. Say for now 2 subject has been created - Maths & Physics
I've created 2 xpage:
a. Submit.xsp - to create new submission (using form - Submit)
b. SubmitView.xsp - to display the list of submission (using view - Submit)
For Submit.xsp, here's where my problem begins:
a. The controls in here are as follows: SubmitID EditBox, Repeat Control(inside is a CheckBox, a fileUpload, and a fileDownload)
b. The repeat is based on the list of subject available. The CheckBox title will be each of the SubjectName. In the OnChange event of the fileUpload control, each time after a file is browsed, the checkbox will get checked and this worked.
c. The fileUpload should only update the accompanying fileDownload but instead the attachment that I just uploaded is reflected to every other fileDownload control. I'm doing full refresh on the fileUpload OnChange because that's the only way for the fileDownload to be updated. What is wrong here and what should I do to get the result that I wanted? Saving the document and opening it later in both read-only or edit mode is fine although each subject still display the same list of uploaded files. Both fileUpload and fileDownload are binded to the SoftCopy field.
Unless I'm not correctly interpreting your description, you're binding multiple upload / download controls to the same item ("SoftCopy"). Because these controls are always bound to an item, not to each other, a download control will show any attachments stored within the source item, regardless of how they got there. To limit display of attachments in a download control to those sent via a specific upload control, they must be stored in an item unique to that pair.
For example, if each pair were bound to a subject-specific item, such as "SoftCopy_Maths" or "SoftCopy_Physics", then each download would only display attachments stored within that specific item. You don't know what subjects will be defined, so you can't define these fields on the form, but that's okay... you don't need to. NSF has no schema, so a field need not be defined on a form for a control to be bound to it; the item will be created when the document is saved, even if the form does not define it. Strictly speaking, even the form itself need not exist.
We typically bind controls to items using dot syntax, e.g. #{currentDocument.SoftCopy}, but array syntax is equally valid, e.g. #{currentDocument["SoftCopy"]}. So if you wrap these controls in something that establishes the dynamic item name as a variable or property, you can use array syntax to target that dynamic item. Two of the best ways to do this are data contexts and custom controls.
For instance, you could surround the contents of the repeat in a panel, and define a panel-specific dataContext that associates the variable attachmentItemName with the concatenation of the item name prefix and the specific subject. Your upload and download controls can then be bound to #{currentDocument[attachmentItemName]}.
Alternatively, you can move the same content to a custom control that accepts the data source and item name as properties, in which case your value binding might look like #{compositeData.dataSource[compositeData.attachmentItemName]}.
Apart from very minor differences in runtime performance, either approach is equally valid.
I've value prompt with ui:checkbox group
parameter: p_IsLastMonth
Name: Prompt_IsLastMonth
ItemCount: 1; UseValue:Yes, DisplayValue: LastMonth?
and two Date Prompts.
Whenever the checkbox is checked, the UseValue 'Yes' is passed to the parameter 'p_IsLastMonth'. But whenever the checkbox is left as it is, it results in an error.
Element 'selectOptions' is not valid for content model: 'All(style,defaultSelections,conditionalStyles,conditionalRender,XMLAttributes)'
I also tried giving a default value. But the default value has to be in the collection. But i want only one checkbox to be displayed.
I tried with html checkbox. But i'm not able to send the value 'either yes or no' to the parameter through javascript because however the finish button overrides the value.
Any help?
There are 2 ways you can use Parameters:
Evaluate Parameter value
Evaluate expression against Parameter value.
Either way your Parameter has some value, and no value is a kind of value. And you need to cater for empty value in some way. Eg:
If (?Parameter? <>'') then ([Selection Criteria] = 'True') Else (1=1)
OR
([Selection Criteria] = ?Parameter?) OR ?Parameter? = ''
There other ways of using parameters too. You should choose one that better suits situation and coding practices you are following.
You can use optional checkbox or text item. In Cognos 10 I get "Deselect" option under checkbox group.
Unfortunately, I don't think you can accomplish what you want to do with only one checkbox. The only way you can leave a value prompt unselected and still submit the prompt page is to make it "optional", which means no value will be passed. An option is to use two check boxes and make them "required" so that either "yes" or "no" must be selected (but this can result in both being selected, which isn't good), or preferably use a radio list with two values and "yes" as the default. There may be a javascript answer to this, but I try to avoid that as much as possible since it sometimes leaves you open to version upgrade issues. Using a radio list is your easiest option.
Well here is something that will work. I've done advanced scorecarding and dashboarding for years with Cognos and Javascript will work:
Create a real cognos parameter that has both choices you need Yes/No with no being the default. Put them perhaps in a html table somewhere off the main real-estate of the report/param canvas. Once you have the param configed you can make the size as small as you want and then make the table/checkbox invisible by turning the visible property to no. Basically the users won't see these params. Don't do box-type = non or the parameter won't even get generated. You could also wait on hidding them until we get step 3 working(Make it easier to troubleshoot).
Then create a HTML parameter that the user will use to interact with in the style that you want the users to see, and use javascript onchange events to manipulate the real hidden parameter by finding it via DOM model. You can make finding it easier by perhaps surrounding the hidden params with an HTML tag that has a unique name/ID and referencing the child items from there.
Since your cognos parameter is invisible you may not even need to use a check box... you could simply use a hidden text box that has stores Yes/No. This will make your coding simplified on the javascript until you get used to it.
Also When programming with javascript on Cognos i find using alert to echo a object's innerhtml to screen while troubleshooting to be very handy.
* One other less impressive approach if i remember right as well..
1. Leave your original cognos style checkbox alone and create another cognos prompt that is always defaulted to "-NO-" and hidden on the canvas.
2. In the expressions used to evaluate the parameters the would evaulate the concatenation values of both params and you could take logical action based on those values. So if the concatted results were "-No-" then you know the original paramater was not selected and to use "No". etc... I believe there could be a nuance to getting this to evaluate correctly in the expression editors but i have got this owrking before as well. * So i your case if the concatted results first 3 characters = "Yes" the "Yes" otherwise no.
