Hi,

I am trying to pass a value from Visualforce page to Controller, by clicking on image with <apex:commandlink /> from PageBlockTable Column. Though I found some solutions where if I don't use PageBlockTable then it works so great. But I have to use PageBlockTable as per my requirement. 

Here is a code for my Visualforce page:

<apex:outputPanel id="resultPanel" >
    <apex:outputText ><b> {!SelectedValue} </b></apex:outputText>
</apex:outputPanel>

       <apex:pageBlock id="Skulls">
            <apex:pageblocksection id="pbsSkulls" rendered="true">
                <apex:pageBlockTable id="pbtSkulls" value="{!lstSBones}" var="SB">
                    <apex:column >
                        <apex:commandlink onclick="callActionMethod('{!SB.Skulls__c}');" >
                            <apex:image url="{!$Resource.Plus}" height="20" width="20"/>
                        </apex:commandLink>
                    </apex:column>
                 </apex:pageBlockTable>
            </apex:pageblocksection>
         </apex:pageBlock>

         <apex:actionFunction name="readCell" action="{!readCellMethod}" reRender="resultPanel" >
             <apex:param name="SkillNExpertise" assignTo="{!clickedCellValue}" value="" />
         </apex:actionFunction>

         <script type="text/javascript">
            function callActionMethod(txtSkull) {
            readCell(txtSkull);
         }
         </script>

And here is my controller where I am trying to receive value.

    public String clickedCellValue { get; set; }
    public String SelectedValue { get; set; }
        
    public void readCellMethod() {
        SelectedValue = 'Selected Value: ' + ClickedCellValue;
    }    

Any input would be really appreciated.

Thanks,

Sawan
