So my question is is there any other way to change the value of the ComboBox when its store is empty or doesn't contain a record with valueFiled equals to value?
You figured it wrong. Please check whether it is possible that you have set forceSelection: true on your combo, as this would induce the behaviour you described. Learn more. Asked 4 years, 3 months ago. Active 4 years, 3 months ago. Viewed 2k times. Try the select method. Dec 21 '15 at I don't understand I don't think the select method not event will work, because in the code that method just calls setValue internally.

Why are you trying to set a value when there isn't a list of values to choose from? Maybe you can use the emptyText config to display a value when none is set? Actually it is an old functional behaviour that was developed with extjs 1 and I'm trying to migrate to version 6.
In that version we could set any value to the comboBox regardless the state of the store. For emptyText it's not a solution because the value to set to the comboxBox changes depending on other value selected before Active Oldest Votes. You want setRawValue instead of setValue. I ended up using this method, but I had to check if my store is empty or doesn't contain a record with valueFiled equals to value before using it.
Alexander Alexander Actually your example is wrong compared to my questionjust add a valueField : 'attribute' to your comboxBox and your example won't work any more Concerning forceSelectionit's kept by default false I have added valueField: 'attribute' to the example.
I don't see any change in behaviour. It is still working. Sorry I gave you the wrong link, check this fiddle. I am trying to match your code to your question.

The data loads fine on edit but is initially blank. I have read the ExtJS docs and all the threads I could find on how to set the initial value, but none seem to work.

Quote from: goldsky at Aug 13,PM You need to remove that ,renderer It's just the rendering of the current value when not editing that is the issue for me. Is the processor sending the value for "organizer" key?
CMHWorks Reply 7, 4 years, 7 months ago. CMHWorks Reply 9, 4 years, 7 months ago. Yeah I read it and responded. The other issue was resolved. Before I posted this diddy. Thanks much!
Quote from: harveyev at Aug 13,PM Maybe should add this diddy to the combobox docs for remote as there is only a local example there.However, the flexibility offered by a combobox comes at the expense of having to navigate through a minefield of configuration options. In the first article in this series I'll attempt to introduce some of the basics. At its heart a combobox is just a glorified textfield.
To the right there is a little arrow known as a trigger. Typing in the field or clicking on the trigger causes a drop-down list of values to be shown. Selecting a value updates the text in the field. Let's see just how simple a combobox can be when we strip away all of the optional configuration.
There are a few key features you should note for this very simple configuration:. Setting editable to false will stop users being able to type in the comboboxforcing them to choose an option via the mouse or keyboard navigation instead.
This configuration makes sense when there are a small number of options and all of the possible values are known in advance.
It is an alternative to using radio buttons. A combobox will usually take up less space on the screen but radio buttons allow the user to see the available options immediately, without needing to click on a trigger. Whilst it may be tempting to set editable to false it isn't without its drawbacks. For a long list of values it can be difficult to find a value in the list. Allowing typing provides a quick and easy way to filter values based on the first few letters.
In some cases the full list of values isn't even available and needs to be requested from a server as the user types. In cases like these, setting forceSelection to true can prove to be a less restrictive alternative to using editable.
It limits the user to picking one of the values in the list without disabling typing. Notice how you can type any value you like into the combobox but if you click away it'll revert back to the last valid value. In cases where typing is enabled it can be desirable to hide the trigger. This is especially true for an 'auto-complete' style combobox. Even though the trigger is no longer visible the list can still be activated by pressing the Down arrow key.
It also shows when the user starts typing. Another option that works well for an 'auto-complete' combobox is typeAhead. As the user types, the text in combobox is extended to match one of the values in the list. The extended text is automatically selected so that it will be replaced if the user continues to type.
By default, clicking the trigger will show all of the possible values in the drop-down list. Setting triggerAction to 'query' will cause the list to be filtered by the current text, just as it would if the list had been activated by the user typing.
The name query may seem a little counter-intuitive. It makes a lot more sense when you consider the case where the list of values is loaded remotely from a server. In that scenario the text is used to query the server for a list of suitable values. For a remote query there's actually no reason why the values listed need to start with the query text at all: it really can be thought of as a query rather than a filter.
Using this configuration with local data can actually be a little irritating.This question has been answered by goldsky.

I'm migrating my application from ExtJs 3 to 4 version. I have several comboboxes at my formPanel, and previously I've used hiddenName and all that stuff to submit valueField instead of displayField. All my adaptation works fine value field IS submittingbut I can't set the default values for comboboxes, they are shown as empty after page load. Previously, I did that just with specifying the 'value' parameter in config. Is there any ideas how to fix that? I had the same problem, afaik has to do with selectlist rendering before the items are added to the store.
I tried the callback method mentioned above without any luck guess it would have to be a callback on the selectlist rather than the store. Adding loading: true to your store config will fix it. There seems to be a problem with autoLoad: true and forceSelection: true. This little hack will make your combobox believe the store is loading even if the load function hasn't been fired yet.
The best way for doing this is that listen to afterrender event and then set the default value in the callback function.
I noticed your Combo config has queryMode: 'local'. That value is intended for when your data is stored locally in an array. But your model is using an AJAX proxy. Could it be that this confuses Ext so it can't find the default value you're trying to set? Try removing queryMode so it defaults to the value of 'remote' or set it explicitly. I'm sure queryMode is part of it, but the main problem is that the combobox doesn't have the data needed yet at the time it's rendered.Many classes have shortcut names used when creating instantiating a class with a configuration object.
The shortcut name is referred to as an alias or xtype if the class extends Ext. Framework classes or their members may be specified as private or protected. Publicprotectedand private are access descriptors used to convey how and when the class or class member should be used. Public classes and class members are available for use by any other class or application code and may be relied upon as a stable and persistent within major product versions.
ExtJS ComboBoxes – Part 1
Public classes and members may safely be extended via a subclass. Protected class members are stable public members intended to be used by the owning class or its subclasses. Protected members may safely be extended via a subclass. Private classes and class members are used internally by the framework and are not intended to be used by application developers. Private classes and members may change or be omitted from the framework at any time without notice and should not be relied upon in application logic.
Below is an example class member that we can disect to show the syntax of a class member the lookupComponent method as viewed from the Ext. Button class in this case. This may be overridden in subclasses when special processing needs to be applied to child creation.
The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.
Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type this count is updated as filters are applied. Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.
Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.
Your page history is kept in localstorage and displayed using the available real estate just below the top title bar. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. Within the history config menu you will also see a listing of your recent page visits.
Clicking on the button will clear the history bar as well as the history kept in local storage. If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled.
Both API docs and guides can be searched for using the search field at the top of the page. On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.

Populating a ComboBox using a simple array of strings Dear All, I'm struggling how to display with ExtJS 4 a simple combobox which values come from a simple array of strings. My use case is much more simple, I have just an array of strings.
