Display a VF page after clickin on command button, depending on selected value from list box

Hi,

 

i am new to salesforce. i hv a simple doubt:

 

 

 public PageReference GotoCSV() {
 
  if (selectedValue == 'FlatFile')
            {        
  PageReference newpage = new PageReference('/apex/UploadAccounts1');

           newpage.setRedirect(true);
           return newpage; 
}
    }

 

i want to display 'UploadAccounts1' page when user selects 'FlatFile' from the dropdown list and clicks the command button.  however m getting following error in the controller   "Non-void method might not return a value or might have statement after a return statement"

 

 

this is my VF page:

<apex:form >
        &nbsp;&nbsp; <font color='grey'> Connection type &nbsp;&nbsp;  </font><apex:selectList id="chooseColor" value="{!string}" size="1">
         <apex:selectOption itemValue="Any connection type" itemLabel="- - Any connection type - -"/>
         <apex:selectOption itemValue="FlatFile" itemLabel="Flat File"/>
                 <apex:selectOption itemValue="SQLServer2008" itemLabel="SQL Server 2008"/>
            <apex:selectOption itemValue="MsAccess" itemLabel="MS Access"/>
        </apex:selectList>

<apex:commandButton action="{!GotoCSV}" value="Create Connection" id="theBtn1" style="width:100px; height: 25px;"/>     
</apex:form>

 

Can anyone please provide a solution

Change to this

public PageReference GotoCSV() {

if (selectedValue == 'FlatFile')
{
PageReference newpage = new PageReference('/apex/UploadAccounts1');

newpage.setRedirect(true);
return newpage;
}
return null;
}

Hi,

 

I tried adding    return null;  but then it remains on the same page no matter whatever I select from the drop down.

 

Please provide another solution

Make sure your are slectimg selectedValue as "FlatFile".Only in that case, page will be navigated to UploadAccounts1 screen
