I have an input field.

<apex:inputField label="Label:" value="{!User__c.attribute__c}"/>

And based on the written input, I'd like to have another field shown/hidden. (I rerender second inputfield after changing first inputfield)

 <apex:inputField label="Label 2:" value="{!User__c.attribute2__c}" rendered="{!IF(User__c.attribute__c='something',true,false)}"/>

But I assume, that I cannot get value from first field like that.

My question is how to get value from inputfield, so I can use later it in "rendered"?

When I create a new user, I have option to select type of user (it can be either x or y-Picklist). And now if I select type x, inputfield called "something" will show (by default it is hidden). And if I select type y, this inputfield will hide. I hoped it would work like this, but it does not.

I have the following code:

 <apex:form >
          <apex:pageBlock title="Create new user" tabstyle="User__c">
               <apex:pageBlockSection columns="1">
                  <apex:inputField label="Name" value="{!User__c.name__c}"/>
                  <apex:inputField label="Type of user" value="{!User__c.type__c}">
                      <apex:actionSupport event="onchange" rerender="something"/>
                  </apex:inputField>
                  <apex:pageBlockSection id="something" rendered="{!IF(User__c.type__c='x',true,false)}">
                      <apex:inputField label="Something: " value="{!User__c.something__c}"/>
                  </apex:pageBlockSection>
               </apex:pageBlockSection>
             <apex:pageBlockButtons >
                 <apex:commandButton value="Save" action="{!save}"/>
             </apex:pageBlockButtons>
          </apex:pageBlock>
      </apex:form>

Can anybody help me?

My question is how to get value from inputfield, so I can use later it in "rendered"?

I'm new on salesforce.

I'm trying to create dependent fields according to picklist value selection.

In the following code I want:

1: when I select "None" in picklist no field should display.

2: if I select 1st option in the picklist; only field1 should get display.

3: if I select 2nd option in the picklist; only field2 should get display.

3: and if I select 3rd option in the picklist; all the fields1,2&3 should get display.

Please Help me out of this task.. Thanks!
