[CLOSED] Unable to change grid cell attributes

[GLD]

Hi

The following code selects the cell in a grid via data returned from the Controller - I've checked, it does point to the required cell:

var cell = masterAccountRelatedAddressesGridPanel.getView().getCell(index, errors[i].Column);

The following code is an attempt to change some of the Cell attributes, though ultimately we want to set the cell to 'invalid':

cell.style.setAttribute("borderBottomColor", "red");
cell.style.setAttribute("borderTopColor", "red");
cell.style.setAttribute("borderRightColor", "red");
cell.style.setAttribute("borderLeftColor", "red");
masterAccountRelatedAddressesGridPanel.getView().refreshRow(index);

It has no apparent effect. How do we change the attributes of a Grid Cell and/or change it to 'Invalid'?

Thanks
