B4J Question How to update a column in a TableView

[Mikelgiles]

Another advantage of nodes is that they can be easily updated. The attached example creates a table with two columns. The second column can be updated:

Where can I find the' attached example' code for updating a column in a tableview?

Could you point the post where you quoted it?

If you are in the need to update values directly from the tw, then you may want to use informatix tableview extended.

If you prefer to update values with external controls (passing the row in to text fields and a button to save the information back into the tw) then its easy with

Tw.selectedrowvalues()

Or the event tw selected row changed

Mmmm if you are refering about this one:

In the very first post at the end you can find the example.

Or for what I understand is that you want to update the whole column?

I looked in the tablExample.zip file but I did not see anything that looked like it was updating anything. I will take a closer look. And no to the whole column. I need to update a single cell rather than a whole column or row. I think I may have found a sub program that does it that I am going to try.

oh okey okey i understand.

Actually is easy to update a cell.

'For the selected row
tw.selectedrowvalues(0) = textfield1.text

'I did not test the code here, but this should work for non selected rows: 
dim row() as string = tw.items.get(0) 
row(0) = textfield1.text

'This is part is necessary for the tw to redraw itself (not reloading)
tw.setcolumnvisible(0,false)
tw.setcolumnvisible(0,true)
