Hi guys i was wondering how to add rows in a pageblock table. for example you want to make a to-do list. each row is a task.  The columns of the table are task(DropDown list), Deadline(Date), Hours worked(Double). If you want to add a task you click on the Add Row button and adds a  row to the table.

hi, i have this table in my visual force page. the fist column of the table is a select option and the others are text. I have a button "add row". This button adds a row to the table, however, because the table needs to be rerendered for the table to show the new row. This causes all select options to go back to the default value. How can you make it so when u click add row each row still has its original select option from before and not the default value. here is the code

<apex:page>

I have an object called book. I want to make a custom button for the book__c object called sell. If the book has been sold(book__c.book_Status__c == 'Sold') a message will display saying that the book has been sold. otherwise the button will take you to another visualforce page called book sell. does anyone have any suggestions.

hi, I have this object book and a custom field comments__c. i want a user to be able to enter comments about the book in another page and view the comments of the book in another page. my controller is something like this

public class bookComments{

public String bookComments {get;set;}
public List<auction__c> auctions;
public List<String> bookIds = new List<String>();

public List<auction__c> getmybook(){

  auctions = [Select id, Name, BookAuctionId__c from action__c where id =: BookAuctionsId__c];

return auctions;

}

public PageReference acceptBookComments(){

for (auction__c b: auctions){
bookIds.add(c.id);
}
public List<books__c> mybooks = [Select id, Name, comments__c, bookAuctionsId__c from books__c where bookAuctionId__c IN bookIds ]

for (auction__c c: auctions){

mybooks.comments = bookComments
}

update mybooks;

}


}

 Then the visualforce page is like this.

<apex:page>
<apex:form>
<apex:dataTable var="auction" value="{!mybook}">
<column>
<apex:outputField value="{!auction.Name}"/>
</column>

<column>
apex:inputTextarea value="{!bookComments}"/>
</column>

</apex:dataTable>

</apex:form>
</apex:page>



Then i have another page that is supposed to show the comments entered.

<apex:page>
<apex:form>
<apex:dataTable var="books" value="{!showComments}">
<apex:outputField value="{!books.comments__c}"/>

</apex:dataTable>
</apex:form>
</apex:page>

 Sometimes it works, sometimes it doesnt

hi lets say we have trigger that is triggered when object__c is update. then what does for (Object__c c: Trigger.New) mean. Is it a for each loop that goes through every record that has just been updated for the object__c

hi, im new to salesforce and i was wondering what was the difference between __c and __r when refering to a custom object. Also can u give me examples. thanks
