Remove Row Dynamically from a Pageblocktable

Hi All,

 

I have a pageblock table in a visualforce page say created for object Opportunity …

 

Inside  the page block table I created another one table for object Product…..

 

I used Map like Map<Oppty,List<Product>> to populate Opportunity values and corresponding product values in to the table

 

and the table is editable to add new values……..

 

In Edit Mode ,I have added “AddRow” link to add new rows in the table and Delete Row link to delete a particular row in the  table….

 

Since I am using using the Map in the page block table I am not able to write a method for “Delete Row” link ...

 

Please anyone suggest..

Hi,

 

Try with  wrapper classes.

It would have been much better if you had pasted your code here. However, from what I understand, you need to call the Delete method and pass in the ID of the row you are deleting.

 

That way, you wouldn't need to worry about removing it from the Map. Just delete it using the DELETE keyword, and then rebuild your map and that should fix your issue.

Hey Barathi,

 

Thanks for the suggestion ...

 

Already I had an idea of changing the entire code using wrapper class. Now I have changed using wrapper class , now its working.

 

Thanks

Hi Cloud Sticker,

 

I am having a similar issue with a pageblocktable, and wanting to delete a row in the table and rerender it.

 

How did you solve this? When you say wrapper class, does this mean you wrote it in Javascript?

 

Thanks very much in advance.

Hi Alibaba,

 

I just used the remove() method with the list to remove the selected row.

 

All you have to do is to pass the rownumber of the particular row using apex:param.

 

then in a write a method for deleting the row.

 

public void delRow()
    {
        rowNum = Integer.valueOf(apexpages.currentpage().getparameters().get('index'));
        memberAddList.remove(rowNum);  
    }

CloudSticker,

 

Thanks so much.

 

One last question, how does the Param attribute know the row number? Do you use a wrapper class to store the row number? Is there an easy solution that I'm missing here?

 

Thanks again!
