[SalesForce] how to call another visualforce page from an apex command button

I have an Apex command button in my Visual Force page. Using that button I want to call another visual force page, which in turn should call action function written in the controller.

Please advise.

Put the below code in the controller action method that is being called on click of command button


PageReference pr = new PageReference('/apex/yourVFPageName');
pr.getParameters().put('key','value');
pr.setRedirect(true); // If you want a redirect. Do not set anything if you want a forward.
return pr;

Edit: ~~In the constructor of the 'yourVFPageName' page controller you can call any method.~~

As @Vigneshwaran G has mentioned:

use action attribute in page to call that method. Otherwise if the method being called from constructor contains any DML statements it will throw error.

[SalesForce] How to call a standard controller action of a VF page from a VF component

This should be doable by passing an argument of type ApexPages.Action to the component

<apex:page standardController="Account">
 <apex:form>
   <apex:pageBlock title="My Content" mode="edit">
   <apex:pageBlockButtons>
    <apex:commandButton action="{!save}" value="Save"/>
   </apex:pageBlockButtons>
   <apex:pageBlockSection title="My Content Section" columns="2">
    <apex:inputField value="{!account.name}"/>
    <apex:inputField value="{!account.site}"/>
    <apex:inputField value="{!account.type}"/>
    <apex:inputField value="{!account.accountNumber}"/>
  </apex:pageBlockSection>
 </apex:pageBlock>
 <c:exampleOne saveAction="{!save}"/>
 </apex:form>
</apex:page>

Component: exampleOne

<apex:component >
   <apex:attribute name="saveAction" type="ApexPages.Action" required="true"/>
   <apex:commandButton action="{!saveAction}" />
</apex:component>

This example is covered in the excellent book Visualforce Development Cookbook by the inestimable Keir Bowden (aka @BobBuzzard)

[SalesForce] Command Button CSS appending btn or call action from HTML5 button

There two things you can try:

Avoid Salesforce standard style:

<apex:page standardStylesheets="false" >

Or trigger a controller method from javascript: Declare an action function (apex:actionFunction tag) at the end of your form and call that function from javascript when doing click on button. See here: https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_compref_actionFunction.htm.
