I have a combobox which I would like to populate with some info. Below is the code:
cmbSelectProject.Items.Clear();
cmbSelectProject.ValueMember = "Sid";
cmbSelectProject.DisplayMember = "Name";
cmbSelectProject.DataSource = new BindingSource(ApiCaller.LstProjects, null);
So, there is a class Project with the existing properties "Sid" and "Name". ApiCaller.LstProjects call returns a list of Projects. So I expect the "Name" to de displayed and "Sid" is used as value.. Instead I see the bunch of Project objects displayed in the dropdown.
What am I doing wrong in here? Thanks for the suggestions.
Try This sequence.
Set DataSource property.
Set ValueMamber and DisplayMember.
Refresh Combo. using Refresh() method.

I have object array which contains objects along with many properties. I am binding it to the select tag using angular ng-options
Demolink
Once user selects the value in the combobox, controller property is updated(here it is $scope.selectedIem={"selected":""}). But this selected propriety contains all the property list name.
eg:
{"description":"Bank",
"shortDescription":"dd",
"value":"xx",
"enable":null,
"name":"jhon"
},
But I want only
{
"shortDescription":"dd",
"value":"xx",
},
Kindly, help me how can pass only required properties to "select object" by using ng-options
You can do this by using ng-change, when your are selecting an object you just need to call a function using ng-change and in that function you need to deleted the unwanted attributes of the selectedItem in ng-model
Here is the working plunker

I have a textfield and would like to not make it read only if a value is selected from a shuttle (many options can be picked). I am using Jheadstart to create the page, but an adf solution works just as well as I can just insert that change into ta template.Normally I would use a binding and select the input value of of another field, but I am not sure what to select with the shuttle as a shuttle can have many selections.
To get the values from the shuttlebox inside a bean:
BindingContainer myBC = this.getBindings();
JUCtrlListBinding listBinding = (JUCtrlListBinding)myBC.get("ViewObject1"); //viewObject that populates the shuttflebox
Object str[] = listBinding.getSelectedValues();
if(str.length>0)
isTextBoxDisabled=false;
else
isTextBoxDisabled=true;
Then bind the Disabled property of the inputtext to myBean.isTextBoxDisabled
This would need a page submit in order to activate, so I'm guessing that's not what you are after.
If you want it to automatically update the values as their are moved around in the shuttle, you will have to use the ValueChangeListener property of the shuttle, in which to get the size of the selections.
public void selectValueChangeListener(ValueChangeEvent valueChangeEvent) {
ArrayList list = new ArrayList(Arrays.asList(valueChangeEvent.getNewValue()));
if(list.isEmpty())
isTextBoxDisabled=true;
else
isTextBoxDisabled=false;
//refresh the inputText component
AdfFacesContext.getCurrentInstance().addPartialTarget(myInputText);
}
Bear in mind the ValueChangeListener will only get processed via their bean method when the page is submitted. If you want the change processed when changing the value of the shuttle, set autoSubmit = true.
I am maintaining a site that allows users to create a profile of sorts that will allow them to broadcast activities to a feed. I implement ng-grid to keep track of all the profiles that are created, and have created two buttons that allow users to create/edit these profiles. My only problem right now is, when users select a row on the grid and attempt to edit that specific row, the drop-down menu is not auto-populated with the data from ngModel.
This is the part of the form I am having trouble with:
<select ng-model="source.canSendTo" ng-options="value.name for value in sourceCanSendTo" data-style="btn" bs-select></select>
And within the controller, I have sourceCanSendTo defined as:
$scope.sourceCanSendTo = [ {"id":"abc", "name": "ABC"}, {"id":bcd", "name": "BCD"} ... ];
On row selection, I simply set source = the selected item, and console.logs show that all the data is there. The other parts of the form are being populated properly (mainly s), and console.log($scope.source.canSendTo) shows that the original data is there, it's just that select is defaulted to being blank...how would I go about trying to pre-select certain elements on the drop-down select I currently have?
For example, if the profile has 'abc', 'bcd' selected, how can I make it so that when I edit that profile, the drop down box shows 'abc,bcd' instead of just "Nothing Selected"?
Edit: I previously responded to a comment inquiring about bs-select, saying that it simply controlled some CSS elements of the drop down box - seems like this is completely incorrect after a quick google search when everything else led to dead ends. Does anyone have any idea how to properly initialize the model with data so that when I preload my form, the 'can send to' drop down select actually has the selected options selected, as opposed to saying "Nothing Selected"? Thanks in advance for all help!
As you are binding source.canSendTo to the name (value.name) of sourceCanSendTo then you just need to initially have an structure binding the names which had been saved, something like this:
source.canSendTo = ['abc', 'bcd']; //And all the selected values
So you need to construct your source.canSendTo property to this structure.
PS: If you show how you bring your data from the server, I can help you to construct the source.canSendTo property.
$scope.canSendTo must be initialized with a reference to the selected option.
var initialSelection = 0;
$scope.source = { canSendTo : [ {"id":"abc", "name": "ABC"}, {"id":bcd", "name": "BCD"} ... ] };
$scope.canSendTo = $scope.source.canSendTo[initialSelection];
Finally found out what was wrong with my code - seems like the data being stored in the model wasn't the same as what was in ngOptions, played around a bit with ngOptions and managed to get something that works. Working snippet of code:
<select ng-model="sendTo.name" ng-option="value.name as value.name for value in sourceCanSendTo" data-style="btn" multiple bs-select>
(Realized that the variable being used for ngModel was a fairly ambiguous in terms of naming convention, changed it)
I am having a problem binding data retrieved from the server to a drop down list. The main issue I think is the fact that the comparison is done on differing object types.
For example:
1. The object returned from the server contains a currency code string. we want this to be bound to an item in the dropdown list
"baseCurrencyCode":"GBP"
The view model returns the list of currencies.. These are returned as a list of currency objects with different properties
{"currencies":[{"id":1,"rateId":0,"abbreviation":"AFN","description":"Afghani","rate":0.0,"rateDescription":null,"languageCode":"en-gb","isDefault":true,"fullDescription":"AFN - Afghani - ","shortDescription":"AFN - Afghani"}}
etc.
Currently, I have got this working by writing a function to go through every property for every item in the list, find the correct property we wish to compare to - do the comparison and then return the initial selection.
When calling my save method I then need to manually bind the currency abbreviation to the object I wish to return to the server.
Surely there must be a better way to do this?
Some of my code for reference..
<select ng-model="selectedCurrency" ng-options="currency.shortDescription for currency in viewModel.currencies"></select>
// Call to my custom method..List, PropertyName, value to compare
$scope.selectedCurrency = InitialiseDropdown($scope.viewModel.currencies, "abbreviation", $scope.updatedObject.baseCurrencyCode);
// Code executed when saving - to bind the currency to the updated object
$scope.updatedObject.baseCurrencyCode = $scope.selectedCurrency.abbreviation;
Any help is appreciated!
EDIT
Sorry if I wasn't clear enough.. To summarise..
The main problem here is binding to the drop down and initial selection.
The object we are updating contains a parameter (string) of the currency abbreviation.
The list we select from is a list of currency objects. As these are two differing object types I have been unable to plug in angulars 2 way binding and have written some code to do this on initial retrieval and when saving.
The cleanest way to fix this would be to return a currency object in our retrieval instead of a simple string of the abbreviation, but this is not an option.
Is there a better way of enabling 2 way binding on different object types ?
Thanks again
It is not exactly clear what the problem is, but you can save yourself some work by binding the <select> to the currently selected currency object (so you don't have to look it up later).
select + ngOptions allow you to bind to one value while displaying another, with the following syntax:
<select ng-model="selectedCurrency"
ng-options="currency as currency.shortDescription
for currency in viewModel.currencies">
</select>
In the above example, $scope.selectedCurrency will be bound to the whole currency object, but currency.shortDescription will be displayed in the dropdown.
See, also, this short demo.
UPDATE:
In case you don't need to bind to the whole currency object, but just bind updatedObject's baseCurrencyCode property to the abbreviation of the selected (in dropdown) currency, you can do it like this:
<!-- In the VIEW -->
<select ng-model="updatedObject.baseCurrencyCode"
ng-options="c.abbreviation as c.shortDescription
for c in currencies">
</select>
// In the CONTROLLER
$scope.currencies = [...];
$scope.updatedObject = {
...
baseCurrencyCode: <baseCurrencyCodeFromServer>
};
See, also, that short demo.
I have had the same problem, ng-model and ng-option being from 2 different sources. My ng-model is bound to a value in a json object representing a chosen filename and my ng-option is a list of possible values taken from a csv file.
In the controller I am reading a directory via a Nodejs route, and creating a json array of filenames like this
var allCsvFiles = [{"name":"file1.csv"},{"name","file2.csv},etc..]
The current csv file, i.e. the selected one is stored in another json array
[{"date":"01-06-2017","csvfile":"file1.csv","colour":"red"},{...}, etc].
I was using the following code for the dropdown:
<select type="text" ng-model="file.csvfile"
ng-options="opt.name for opt in allCsvFiles track by opt.name"></select>
Which caused the current selection to be blank and if I selected an item from the dropdown it put [object],[object] as the current selection. If I stepped through the code I found that it seemed to be selecting {"name","file1.csv"} as the option and couldn't display it, this seemed odd as my ng-options selection looks like it should just return the value of "name" not the array entry. I tried many different ways to make this work but eventually I found that if I made the list of possible selections a plain javascript array:
var allCsvFiles = ["file1.csv","file2.csv", "file3,csv]
and changed the select to:
<select type="text" ng-model="file.csvfile" ng-options="opt for opt in allCsvFiles"></select>
then the dropdown selection worked as expected.
I may have missed some other obvious solution here, but as the array of json objects is one dimensional anyway it doesn't seem to be an issue.
It looks like the OPs question has been answered, I just thought I'd add this as it solved it for me.
In Dojo I want to set the first/top option of may Store as the default/displaying option/text of the combo box. I went through the documentation to found no help. if anyone have done that before please share your opinion.
Ps - I can't use ID or name of the option to set it. I want to display what ever the data item somes first in the store to display.
Thanks in advance.
and this is how my combo-box looks like
var Selectbox = new dijit.form.ComboBox({
id: "box1",
disabled:true,
uppercase:true,
autoComplete:false,
trim:true,
value: "boxvalue",
store:detailDataStore,
style:"width:120px; color:black;"
}).placeAt(topContentPane10.containerNode);
There isn't a magic property to set the combobox default selection from a store, you'll have to set it manually.
Something like this:
box.set('value',store.data[0].value)
