Salesforce Unknown property 'String.Name' - salesforce

Question

I want to list the Result of Survey From tables, but I am getting error
Unknown property 'String.Name'
I need to show the result on VisualForce page.
VF page
<apex:page showHeader="false" sidebar="false" controller="SurveyResultController">
<apex:form>
<apex:pageBlock title="Submited Result">
<apex:pageBlockTable value="{!SurveyResult}" var="sr">
<apex:column value="{!sr.Name}"/>
</apex:pageBlockTable>
</apex:pageBlock>
</apex:form>
Apex Controller
public with sharing class SurveyResultController {
public String surveyId {
get;
set{
this.surveyId = value;
}
}
public Integer SurveySessionID {
get;
set{
this.SurveySessionID = value;
}
}
public String ssessionid {
get;
set;
}
public SurveyResultController() {
surveyId = Apexpages.currentPage().getParameters().get('id');
ssessionid = Apexpages.currentPage().getParameters().get('ssessionid');
}
public List<String> getSurveyResult() {
List<tblSurveyResult__c> qr = [SELECT Name,
QuestionID__c,
SurveyID__c,
Answer__c,
QuestionID__r.Id,
QuestionID__r.Name,
QuestionID__r.Question__c,
QuestionID__r.SelectedAnswer__c
FROM tblSurveyResult__c
WHERE SurveyID__c = :surveyId
AND SurveySessionID__c = :SurveySessionID];
List<String> resp = new List<String>();
for (tblSurveyResult__c r : qr) {
resp.add(r.Name);
}
return resp;
}
}

Answer 1

in the following line
<apex:column value="{!sr.Name}"/>
you try to read Name from String entity.
In the controller you prepared a List<String> and return it to the page.
List<String> resp = new List<String>();
for (tblSurveyResult__c r : qr) {
resp.add(r.Name);
}
return resp;
So, your options:
Use the following format on the page
<apex:column value="{!sr}"/>
return list of tblSurveyResult__c to the page
public List<tblSurveyResult__c > getSurveyResult() {
return [SELECT Name,
QuestionID__c,
SurveyID__c,
Answer__c,
QuestionID__r.Id,
QuestionID__r.Name,
QuestionID__r.Question__c,
QuestionID__r.SelectedAnswer__c
FROM tblSurveyResult__c
WHERE SurveyID__c = :surveyId
AND SurveySessionID__c :SurveySessionID];
}
EDIT due to your comments please use the second option
Return list of tblSurveyResult__c to the page
public List<tblSurveyResult__c > getSurveyResult() {
return [SELECT Name,
QuestionID__c,
SurveyID__c,
Answer__c,
QuestionID__r.Id,
QuestionID__r.Name,
QuestionID__r.Question__c,
QuestionID__r.SelectedAnswer__c
FROM tblSurveyResult__c
WHERE SurveyID__c = :surveyId
AND SurveySessionID__c :SurveySessionID];
}
<apex:page showHeader="false" sidebar="false" controller="SurveyResultController">
<apex:form>
<apex:pageBlock title="Submited Result">
<apex:pageBlockTable value="{!SurveyResult}" var="sr">
<apex:column value="{!sr.SurveyID__c}"/>
<apex:column value="{!sr.Name}"/>
<apex:column value="{!sr.QuestionID__r.Question__c}"/>
<apex:column value="{!sr.QuestionID__r.SelectedAnswer__c}"/>
</apex:pageBlockTable>
