I'm new with primeNG and p-tableCheckbox.
I'm using this component to create a checkbox column to check/select the right row. So the normal standard and behaviour works perfectly. But now I need to select by default some row/checkoxes by component.ts.
I'm searching everywhere and I don't find anything about this behaviour.
I tried something like this
<p-tableCheckbox #tableCheckbox [value]="rowData" [index]="rowIndex"></p-tableCheckbox>
checkSelected(event) {
this.checkboxSelected.emit(event.data);
this.tableCheckbox.checked = true;
}
where but obviously doesn't work. How can I make it work?
With p-table pass selected objects like
<p-table [(selection)]="selectedRowDataArray">
This will automatically mark required checkboxes as selected.

In an angular project, I need to test that the displayed table width of the primeng data table is set to the maxWidth value i assign to it. To do so, i want to call the [style] attribute to get the width and see if its equal to my maxWidth. However, i do not know how to call attributes like this. How do i go about this? Currently i have no clue if I'm going in the correct direction.
I have tried several things but I am not sure of the syntax for it.
<p-table class="p-table" ... [style] = "{width: maxWidth}" >
it('should implement maxwidth', () => {
const widthDebug: DebugElement = fixture.debugElement;
const tableWidth = widthDebug.query(By.css('.ui-table .ui-widget'));
const ptable: HTMLElement = tableWidth.nativeElement;
expect(ptable.textContent).toContain("width: " + component.maxWidth);
});
expected: success (ptable.textContent contains "width: component.maxWidth")
actual: TypeError: cannot read property 'nativeElement' of null
I see that it's now two months after you asked your question, so it's probably too late for my answer to help, but I stumbled across this post while looking up something else about PrimeNG, so I might as well give it a shot.
The problem here is that nativeElement is defined on Dialog class instances of the Angular p-table component. It's not defined on any particular DOM element.
By.css('.ui-table .ui-widget') is going to find a DOM element for you, not an Angular class instance. In particular what will be found is a <div> inside the <p-dialog> DOM element, and it's this <div> that receives the style set via [style]=....
As your code is written above tableWidth.style.width would contain (as a string) the value of maxWidth that you're expecting to find.
Hi I am working on a Angular4 application and for UI I am using Primeng.
I have a multi-select element which behaves pretty much the same as it does over here https://www.primefaces.org/primeng/#/multiselect
The only thing I want different is on the drop-down, when "X" (close) button is clicked, I want it to clear all the selection instead of closing the drop-down itself.
Is there any way to achieve that in primeng ?
Help is appreciated !
You can manually trigger the checkbox in the left by jquery.
declare var jquery:any;
declare var $ :any;
$('.ui-chkbox-box.ui-widget.ui-corner-all.ui-state-default').trigger('click')
or you make the value of the p-multiselect equal to [].
Ex.
//html
<p-multiSelect #multiselect>
<button type="button" (click)="functionToClear(multiselect)"</button>
</p-multiselect>
//ts
functionToClear(multiselect): void {
multiselect.value = [];
}
It isn't possible, but you can clear all the selection by clicking the checkbox in the left corner twice.
While it isn't a supported functionality of the Multiselect PrimeNg component, if you really want it to do that, you would have to manually edit the component, multiselect.js, and modify the close(event) function to do what you want.
you can use formGroup and try to clear value following way:
html:
<ng-multiselect-dropdown [(ngModel)]="data"
[data]="fetchedData" [settings]="customeSettings"
formControlName="myControl">
</ng-multiselect-dropdown>
.ts:
this.form_name.controls.myControl.setValue("");
normally the multi-select input in primeng is binded to a property that holds the selected members, usually an array.
you can use a reset button for example that when clicked, it will empty that propery/array and this will clear all the selected check boxes of the multi-select.
Since PrimeNg version 13, you can use [showClear]="true" property to display an 'X' icon next to the control value.
I tried to find on Primefaces Documentation but I have not found how can I customize the filter function for SelectOneMenu.
I add filterMatchMode="custom" filterFunction="#{mainRandevuBean.ilFilter()}"
But I don't know how can I write bean filterFunction.
The filter is a javascript (client-side) function. It all IS in the PrimeFaces documentation, which you should always look into first, carefully, thouroughly.
So use filterFunction="myFilter"
and create a javascript function like
function myFilter(itemLabel, filterValue) {
// return true if this label matches, false otherwise
}
Just as a sidenote: primefaces documentation doesn't say anything semantically about the parameters. It also does not mention where the label comes from (in fact, the docs mention "the item value" which is not very clear).
In fact I used the JavaScript function to debug this in order to figure out what was provided by default as a label.
function filterList(label, filter){
alert("label="+label+" and filter="+filter);
return false;
}
At first I thought it would be anything like the text inside the HTML generated for each list item. But when debugging it I saw the alert said that the label was something like my.package.SomeValueObject#123456 (which is obvously the Java object toString on each item in the list).
You need to define the itemLabel property on the selectItems which is inside the selectManyMenu to generate a proper text value used by the standard filtering mechanisme. As far as I could figure out that is the only reason why you have to put itemLabel there. In the documentation itemLabel is specified before explaining filtering which is confusing.
And as far as I know the itemValue defaults anyhow to just the object value, so I believe following from the documentation is redundant.
itemValue="#{player}"
Hope it helps anyone :.)
I resolve this problem with autocomplete component. Primefaces autocomplete component with dropdown="true" property works like one menu.
Link to form
The form can be found at the link above.
Up until this morning the radio buttons and the form had been working as expected, however now users can't change their answer once they've picked from one of the two radio buttons even though they use the same input name. Using $("#volunteer-form input:radio[name='gender']:checked").val() I've found that the value is being correctly set and that the two buttons are still linked by a common name. Also, it appears possible to switch between the two using a bit of jQuery, like so:
$("#volunteer-form input[name=gender][value=male]").prop('checked', true);
Any ideas?
its because of your javascript block here:
$(document).ready(function() {
$('.inline').fancybox({
'maxWidth': 600
});
$('.form').click(function(event){
event.preventDefault();
});
});
when you are clicking on the radio button inside the form your preventDefault is stopping the change of radiobutton state ... or maybe you already knew that.
What is the intended purpose of including the preventDefault where you have it?
Please note the remark mentioned WORKAROUND at the end of this question.
Based on a Dictionary based specification, one of my classes creates a Form programmatically.
Adding TextInput or DatePicker to FormItemss works as expected.
Unfortunately, the following code just creates a colored rectangle, not the actual picker:
ti = new ColorPicker();
ColorPicker( ti ).selectedColor = TAColor( _spec[ key ].value ).color;
and later on
formItem.addElement( ti );
The Form is embedded in a TitleWindow component presented using
PopUpManager.addPopUp(...);
When added to TitleWindow, it shows up correctly, within Form->FormItem not:
I can't image, why the picker doesn't appear. Do you?
WORKAROUND:
If I wrap the ColorPicker inside a Group things work:
ti = new Group();
Group( ti ).addElement( new ColorPicker() );
In this case, the ColorPicker appears as editable.
Still, I'd be too happy to learn what the problem with my initial solution. Bug?
A DateField (which extends ComboBase like ColorPicker) behaves properly in a spark Form. But in the ColorPicker, the mouse down handler of the button never gets called. I think that maybe the skin part that handles the mouse clicks (it must be a button) is not properly dimensionned, and the result is it is not shown. I've come to this conclusion because within an mx Form, the ColorPicker doesn't display as it does when it is added to the regular displaylist...
Hope this helps...
In the code you've provided, you never add the colorPicker as a child to any parent container; as such it will never show up anywhere.
You probably need to do something like:
formItem.addChild(ti );
[or for a Spark formItem]:
formItem.addElement(ti );
I'm confused as to why you're seeing a rectangle.
