Balakumar Ramachandran 6 <apex:param> not working inside pageblock
VF Page
-----------
<apex:pageblockTable value="{!users}" var="user" >
<apex:column width="20%">
<apex:facet name="header">Owner ID </apex:facet>
<apex:commandlink value="Del" action="{!delCont}" rerender="" >
<apex:param name="contIdChosen" value="{!user.UserOrGroupId}" assignTo="{!contIdChosen}"/>
</apex:commandlink>
</apex:column>
</apex:pageblockTable>
class
=------
public PageReference delCont()
{
system.debug('----------------------------------------Test Me------------------------------');
Id id = System.currentPageReference().getParameters().get('contIdChosen');
Scheme__Share toDel=new Scheme__Share(Id=contIdChosen );
system.debug('----------Id is------------'+contIdChosen );
PageReference nextpage1 = new PageReference('/apex/share/WV_SharingDetails?parentId='+id);
nextpage1.setredirect(true);
return nextpage1;
}
The method delCont itself is not called inside pageblock.. If i place outside it it works fine but i need it inside pageblock..

You won't be able to pass parameters to commandlInk component. You can try to use ActionFunction to pass parameters to your Apex Controller. Here is an example: http://salesforce.stackexchange.com/questions/24175/passing-method-parameters-with-apexactionfunction
now i modify this to
page
--------
<script>
function ClickMe(id)
{
alert(id);
callDelId();
}
</script>
<apex:actionFunction name="callDelId" action="{!delCont}" onComplete="alert('After apex method') ;" />
<apex:commandlink value="Del" onClick="ClickMe(!user.UserOrGroupId);" >
<apex:param name="contIdChosen" value="{!user.UserOrGroupId}" assignTo="{!contIdChosen}"/>
</apex:commandlink >
class
--------
public PageReference delCont()
{
system.debug('----------------------------------------Test Me------------------------------');
system.debug('----------Id is------------'+contIdChosen );
Id id = System.currentPageReference().getParameters().get('contIdChosen');
system.debug('----------Id is------------'+contIdChosen );
Scheme__Share toDel=new Scheme__Share(Id=contIdChosen );
system.debug('----------Id is------------'+Id);
//delete todel;
//setupContacts();
PageReference nextpage1 = new PageReference('/apex/share/WV_SharingDetails?parentId='+id);
nextpage1.setredirect(true);
return nextpage1;
}
how do i pass the id from javascript. i got in the alert the respective id..how do i pass it to controller ??
I tested the same example. which worked fine for me
vf Page:
<apex:page controller="ApexParamExmaple" >
<apex:form >
<apex:pageBlock >
<apex:pageblockTable value="{!users}" var="user" >
<apex:column width="20%">
<apex:facet name="header">Owner ID </apex:facet>
<apex:commandlink value="Del" action="{!delCont}" rerender="" >
<apex:param name="contIdChosen" value="{!user.Id}" assignTo="{!contIdChosen}"/>
</apex:commandlink>
</apex:column>
</apex:pageblockTable>
</apex:pageBlock>
</apex:form>
</apex:page>
Controller:
public class ApexParamExmaple {
public String contIdChosen {get;set;}
public PageReference delCont()
{
system.debug('----------------------------------------Test Me------------------------------');
Id id = System.currentPageReference().getParameters().get('contIdChosen');
//Scheme__Share toDel=new Scheme__Share(Id=contIdChosen );
system.debug('----------Id is------------'+contIdChosen );
PageReference nextpage1 = new PageReference('/apex/share/WV_SharingDetails?parentId='+id);
nextpage1.setredirect(true);
return nextpage1;
}
public List<User> getUsers() {
return [select Id,Name from User];
}
}
Can you please be specific what exactly the issue is
Here is an example:
<apex:outputLink value="javascript:if (window.confirm('Are you sure?')) DeleteQuoteLineItem('TEST VALUE');"> Del </apex:outputLink> <apex:actionFunction action="{!DeleteQuoteLineItem}" name="DeleteQuoteLineItem" reRender="content"> <apex:param name="myParam" value=""/> </apex:actionFunction>If you look closely, the Param is to be added to "ActionFunction" tag, and you can call the action function name directly as a javascript function (you don't need an additional javascript function, i.e. your clickme function can be removed)
You can also check the below link.

<script>
function ClickMe(id)
{
alert(id);
callDelId(id.value);
alert(id);
}
<apex:actionFunction name="callDelId" action="{!delCont}" onComplete="alert('After apex method') ;" >
<apex:param name="contIdParam" value="" assignTo="{!contIdChosen}"/>
</apex:actionFunction>
class
----------
public PageReference delCont()
{
system.debug('----------------------------------------Test Me------------------------------');
Id id = Apexpages.currentPage().getParameters().get('contIdChosen');
system.debug('----------Id is------------'+contIdChosen );
Scheme__Share toDel=new Scheme__Share(id=contIdChosen);
system.debug('----------Id is------------'+Id);
i want to pass the value "id.value" in the apex parameter so that to the method delCont the id is coming..
Are you not getting contIdChosen in this line ?
system.debug('----------Id is------------'+contIdChosen );
