I am displaying a list of items using the selectcheckboxes in a manner virtually identical to the example from the VisualForce documentation on page 210 as reflected below.

I am interested in checking some of the checkboxes as they are displayed, without user input.  What code would need to be added to this example in order for my checkboxes to appear checked as they are being displayed?

Thanks in advance for your help.

I have a button on a Contact details page that launches a Visualforce page.  This Visualforce page uses a custom controller for various reasons, but I need to reference the specific Contact that the user launched from.  Is there an easy way to pass the Contact ID as a parameter to the new Visualforce page and reference it throughout my code?

Thanks..

Hi all,

Not sure if this is possible on Visualforce and how to do it.

I have an extension to a standard controller with some extra functions that will set a field (let´s call it A) to a calculated value depending on another field (let´s call that one B).

Now when B, which is a dropdown field, changes, I want A to be recalculated.

In other words, I want an Onchange event on field B (you can have these type of events) that calls a function within the Controller. The problem is that from an onchange event you can call Javascript, but I don´t know how to call an Apex function from within Javascript.

Can this be done? Thanks,

J

Hi..

I would like the file reference within my URLFOR($Resource) to be dynamic -a variable set in my controller itself. Can this be done? I am trying to show dynamic images in a pdf based on record(some condition). 

 Same type question : http://community.salesforce.com/sforce/board/message?board.id=Visualforce&message.id=9386

  In the above thread Andrew says

           " you can bundle the images into a zip, upload the zip as a static resource and then specify which element within the zip you want to show dynamically. "

         But in my case I have to add images future also and some time I have to delete images. In that case I have to zip all images once again.

        Is there any other way to get a images based on record

Hi

I've got a Visualforce page that contains another page using a composition. Is it possible to access the variables of the child pages controller in the parent page (or pass the variables up from the child page)?

Many Thanks

James

I have a custom object called Merchant_Analysis__c which has a master-detail relationship with Opportunity. There is a field on the custom object called Opportunity__c which is just a reference to the parent Opportunity. I have a simple javascript button on the Opportunity called  New Merchant Analysis which simply passes the opportunity id to the visualforce controller via GET.

In my save method for the controller I set the Merchant_Analysis__c.Opportunity__c field to the ID of the Opportunity

public analysisController()

{

String oid = System.currentPageReference().getParameters().get('id');

if(oid != null && oid != '')

{

Opportunity o = [select id,name from Opportunity WHERE id=:oid];

this.oppID = o.id;

}

}

public PageReference save()

{

analysis.Opportunity__c = oppID;

analysis.recordtypeid = recType;

insert analysis;

PageReference analysisPage = new PageReference('/' + analysis.id);

analysisPage.setRedirect(true);

return analysisPage;

}

 The variable oppID is a public class level String variable that holds the Opportunity ID. For some reason when I run my test methods I get the following error:

System.SObjectException: Field is not writeable: Merchant_Analysis__c.Opportunity__c

 I've checked all the field level securities and everything to make sure Opportunity__c is not read only anywhere. For some reason I cannot figure out how to get past this error or even what is causing it.

Does anyone know how I can set the the relationship field of a Custom Object with a Master-Detail Relationship?

Any help would be great, as this problem has been plaguing me for too long now.

Thanks,

Jonathan

Hi,

I have a Visual Force page for the Opportunity object and need to auto populate the contact field on that page with the name of the contact that the opportunity is created for (when the opportunity is created from the Contact page). I know that this is possible when using the standard Opp page.

Is there a way to do this on a custom Opp page?

Thank you!

Hi,

I've created a VisualForce page and want to disable/enable a lookup field dynamically, based on the values selected in a picklist (i.e. when the value is selected in the picklist, I need the lookup field to be enabled or disabled, depending on the selection).

Any ideas on how to implement this?

Thank you!

I am trying to get the inputfields on a custom new page I've created to show the default field values.  Right now I'm manually assigning the default values to the appropriate fields in my constructor, but it seems like there should be a better way to do this. Anyone have any ideas?

I also have a pageblocktable of child objects on that page (for mass creation.) Is there a way to have the code field (a formula field based on the product field) show up when someone fills in the product field?

child object pageblocktable:

<apex:pageBlockTable border="0" cellpadding="6" value="{!NewItems}" var="item" id="rows">
<apex:column headervalue="Product">
<apex:inputField id="prod" value="{!item.Product__c}" required="false" /> </apex:column>
<apex:column headervalue="Code">

  The following outputfield remains blank no matter what I do. I want it to show the results of the code__c formula

<apex:OutputField value="{!item.Code__c}" />
</apex:column>
</apex:pageBlockTable>

Hi all,

How to display "Required information" along with red bar (like SFDC page)on the Page Block section of visualforce page?  

Thanks.

I'm trying to mimic creating a New Event from the related list section (Open Activities) on Opportunity page through a custom button (called "New Event X"). This custom button, on clicking, should open a visualpage in edit mode. This visualpage is based on a standard controller for Event, has fields from Event and a few other objects.

Here's the problem- I have the visualpage created, but can't attach it to the custom button because the button type is "List Button" and the page is based on a standard controller for Event. If I change the button type to Detail Page Button then I can attach the visualpage to it, but Salesforce requires the custom button to be of "List Button" type in order for it to appear on the related list section of Opportunity page.

I don't want to override the standard button "New Event". It seems like a pretty common requirement, and I'm wondering how others have done it.

Any help would be much appreciated. Thanks in advance.

Hello folks,

I have a requirement to word-wrap and display the column header names of a pageBlockTable. Any idea how to achieve this ? Thanks.

I would ike to dynamically set fields to be read-only (based on another field value) in a Visualforce page using a Custom Controller.

Does anyone have any ideas on how to do this?

Sorry for what might be a stupid question here. I would like the file reference within my URLFOR($Resource) to be dynamic - either a variable set in my controller or in the VF page itself. Can this be done? I am trying to show dynamic images within a page based on which page you are on. Thx.
