Visualforce page reRender

Hi,
I have created an object. Object Name: Text
Fieds:
1. Text Name(Standard field)
2. values (picklist field: values: 1, 2, 3)
3. Text 1 (Text field)
4. Text 2 (Text field)
5. Text 3 (Text field)

Now, I need a vf page. If I select picklist value as '1', then 'Text 1 ' field should be marked as required. If I select value '2', then 'Text 2 ' should be marked as required(red). Here we have to use reRender attribute and fields should be marked as required before saving.


<apex:page standardController="Text__c">
<apex:form>
<apex:pageBlock >
<apex:pageBlockSection id="thePageBlockSection">
<apex:inputField value="{!Text__c.Name}"/>
<apex:inputField value="{!Text__c.Text_values__c}" /> 
<apex:inputField  value="{!Text__c.Text_1__c}" required="{!if(Text__c.Text_values__c== '1'), true, false}"/>
<apex:inputField  value="{!Text__c.Text_2__c}" required="{!if(Text__c.Text_values__c== '2'), true, false}"/> 
<apex:inputField  value="{!Text__c.Text_3__c}" required="{!if(Text__c.Text_values__c== '3'), true, false}"/> 

</apex:pageBlockSection>
<apex:pageBlockButtons >
<apex:commandButton value="Save" action="{!save}"/>
</apex:pageBlockButtons>
</apex:pageBlock>
</apex:form>
</apex:page>

Thank You.

Try the below one, If alignment issue change it accordingly using pageblocksection or css style,
  
<apex:page standardController="Text__c">
	<apex:form>
		<apex:pageBlock >
			<apex:pageBlockSection id="thePageBlockSection">
				<apex:inputField value="{!Text__c.Name}"/>
				<apex:actionRegion>
					<apex:pageBlockSection>
						<apex:inputField value="{!Text__c.Text_values__c}" >
						<apex:actionSupport event="onchange" reRender="requiredPanel"/>
						<apex:inputField>
					</apex:pageBlockSection>
				</apex:actionRegion>
				<apex:outputPanel id="requiredPanel">
				<apex:pageBlockSection>
				<apex:inputField  value="{!Text__c.Text_1__c}" required="{!if(Text__c.Text_values__c== '1'), true, false}"/>

Hi Hitesh,
I have created a record but i am not able to save it without giving "Text 1". "Text1" value becomes required even If i am not selecting any value in Text_Values__c.
