[SalesForce] How to use a VisualForce page to set a custom setting field

I'm trying to create a VisualForce configuration page for my managed package. I have a hierarchal custom setting field for an authentication key which is needed to access a remote service. I can read this value with "{!$Setup.prefix__Settings__c.prefix__Key__c}"

however, if I try making an input field for it using

<apex:inputField value="{!$Setup.prefix__Settings__c.prefix__Key__c}"/>

it says that only sObjects work for inputField values.

I thought merge fields worked too…anyway, how can I let the user type in a key and save that value to the custom settings record? Also, would using a List custom setting be easier or better?

You can set them via Apex controller. Here is some documentation

So it would be something like this (for hierarchy settings):

Apex:

public String myValueFromPage{get; set;}

public void saveMyValue() {
    prefix__MySettings__c settings = prefix__MySettings__c.getInstance();
    settings.prefix__myField__c = myValueFromPage;
    upsert settings;
}

Visualforce:

<apex:inputText value="{!myValueFromPage}">
<apex:commandButton action="{!saveMyValue}" value="Save Input"/>

IDs are dynamically assigned to the page when it renders, so I have never had much luck referencing it in CSS or Jquery selectors.

My suggestion would be to use the styleClass attribute on the apex:inputField tag and reference that class name in your CSS selector. So if your class name is className, try

.className input
{
display:none !important;
}

If that doesn't work, you might have to use some Jquery.

[SalesForce] How to build a complex Visualforce Dynamic Binding dynamically

The expression value can be set in an Apex controller using a dynamiccomponent. Because the expression is built outside of Visualforce, it can be dynamically set based on a Custom Setting. Here's what I ended up with:

Visualforce

<apex:dynamicComponent componentValue="{!SectionsAndFields}"/>

Apex

public Component.Apex.OutputPanel getSectionsAndFields() 
{
    Component.Apex.PageBlockSection PageBlockSection 
        = new Component.Apex.PageBlockSection();

    PageBlockSection.title = 'Section';
    PageBlockSection.collapsible = false;

    for(Field__c f : Fields)
    {
        Component.Apex.InputField InputField = new Component.Apex.InputField();

        if(f.Lookup_sObject__c != null 
        && sObjectsByType.get(f.sObject__c).getSObject(f.Lookup_sObject__c) != null) 
        {
            // use dot notation to reference fields on an sObject
            // use brackets and escaped quotes around a key 
            //   to get a value from a map (sObjectsByType in this example)
            InputField.expressions.value = '{!sObjectsByType' 
                + '[\'' + f.sObject__c + '\']' 
                + '.' + f.Lookup_sObject__c + '.' + f.Field_API_Name__c + '}';

            PageBlockSection.childComponents.add(InputField);
        }

        if(f.Lookup_sObject__c == null) 
        {
            InputField.expressions.value = '{!sObjectsByType' 
                + '[\'' + f.sObject__c + '\']' 
                + '.' + f.Field_API_Name__c + '}';

            PageBlockSection.childComponents.add(InputField);
        }
    }

    return PageBlockSection;
}
