In Visualforce, the Upload Files button can’t be hidden by making the related list read-only; instead, you’ll need to override the standard component with a custom Visualforce page or use CSS/JavaScript to hide that specific button element when rendering the Files related list in Lightning Experience. 

Example

<apex:image id="theImage" value="/img/myimage.gif" width="220" height="55"/>
The example above renders the following HTML:
<img id="theImage" src="/img/myimage.gif" width="220" height="55"/>
Resource Example
<apex:image id="theImage" value="{!$Resource.myResourceImage}" width="200" height="200"/>
The example above renders the following HTML:
<img id="theImage" src="<generatedId>/myResourceImage" width="200" height="200"/>
Zip Resource Example
<apex:image url="{!URLFOR($Resource.TestZip, 'images/Bluehills.jpg')}" width="50" height="50" />
The example above renders the following HTML:
<id="theImage" src="[generatedId]/images/Bluehills.jpg" width="50" height="50"/>

To automatically adjust the zoom so the entire route is visible, you can use the fitBounds() method with the route’s bounds. After setting directions, add:

if (status === 'OK') { 

    directionsDisplay.setDirections(response); 

    var bounds = response.routes[0].bounds; 

    map.fitBounds(bounds); 

} 

This ensures the map zooms and centers itself to show the complete route between your two points.

Hi, 

You'll need a Visualforce page with an Apex controller that calls your GlobalWhetherClass — using a <apex:actionSupport> to re-render the cities list when country changes.  

public class WeatherController {
    public String selectedCountry { get; set; }
    public String citiesResult { get; set; }
    public List<SelectOption> getCountries() {
        return new List<SelectOption>{
            new SelectOption('India', 'India'),
            new SelectOption('United States', 'United States'),
            new SelectOption('United Kingdom', 'United Kingdom')
            // Add more as needed
        };
    }
    public void fetchCities() {
        if (String.isNotBlank(selectedCountry)) {
            GlobalWhetherClass.GlobalWeatherSoap svc = new GlobalWhetherClass.GlobalWeatherSoap();
            citiesResult = svc.GetCitiesByCountry(selectedCountry);
        }
    }
}

<apex:page controller="WeatherController">
    <apex:form>
        <apex:pageBlock title="Weather Lookup">
            <apex:pageBlockSection>
                <apex:selectList value="{!selectedCountry}" size="1">
                    <apex:selectOptions value="{!countries}"/>
                    <apex:actionSupport event="onchange"
                                        action="{!fetchCities}"
                                        reRender="citiesBlock"/>
                </apex:selectList>
            </apex:pageBlockSection>
            <apex:pageBlockSection id="citiesBlock">
                <apex:outputText value="{!citiesResult}" escape="false"/>
            </apex:pageBlockSection>
        </apex:pageBlock>
    </apex:form>
</apex:page>

• User selects a country from the dropdown
• onchange fires fetchCities() via actionSupport
• Controller calls GetCitiesByCountry on your SOAP class
• Result re-renders in citiesBlock without a full page refresh

Make sure

(Setup → Remote Site Settings) — otherwise the callout will be blocked. 

Hope this helps!

List<String> li = new List<String>();
System.debug(li.isEmpty());     // true

<apex:page standardController="Account" extensions="displayImageExtension">
<apex:form >
    <apex:repeat value="{!FileId}" var="v">
        <apex:image url="/servlet/servlet.FileDownload?file={!v}"/>
    </apex:repeat> 
</apex:form>
</apex:page>

Hi Pete,

Here are a few recommendations that might help resolve this issue:

1. Check URL Encoding: Ensure that the URL parameters are correctly encoded. Sometimes, special characters in URLs can cause unexpected behavior.
2. Verify X-Frame-Options: Ensure that the external site allows being displayed in an iframe. Some websites set the X-Frame-Options HTTP header to prevent being embedded in iframes. You can check this by inspecting the network requests in your browser's developer tools.
3. Use Apex:iframe: If you're not already using it, consider using the apex:iframe component instead of a standard iframe. This component is designed for embedding external content in Visualforce pages and might handle URL parameters better1.
4. Update Visualforce Page: Ensure that your Visualforce page is correctly configured to handle URL parameters. You might need to adjust the URL handling logic in your Visualforce page to ensure it correctly parses and redirects to the desired product page.
5. Test in Different Browsers: Sometimes, browser-specific behaviors can cause issues with iframes. Test the behavior in different browsers to see if the issue persists.

Hello, 

To stop the footer from repeating, you should

This works because the -fs-table-paginate property specifically forces <thead> and <tfoot> elements (which facets generate) to repeat on every page break; moving the data outside the table context ensures it only renders once at the very end of your data list.
