Currently, we do not have a feature to modify the text of the FieldList header. However, this could be achieved using a workaround.

If your grid will show Chart initially, we could use javascript to find the element and modify the inner HTML. Here is the snippet to modify the FieldList caption from Chart Field List [ Orders ] to Chart Field List ( Orders )

function WebGrid1_OnAfterInitialize(controlId) 
{
    ModifyDefaultText(controlId);   
}

var t = null;

function ModifyDefaultText(controlId) 
{
    var grid = ISGetObject(controlId);
    var containerId = grid.Id;
    var suffix = "TableFieldList";
    
    var tblElem = document.getElementById(containerId + '_' + suffix);

    if (tblElem == null)
        t = setTimeout(function() { ModifyDefaultText(controlId); }, 20);
    else 
    {
        t = null;
        tblElem.getElementsByTagName("table")[1].getElementsByTagName('td')[0].innerHTML = "Chart Field List<br/> ( Orders )";
    }
}

Thank you Glenn, the workaround worked.

Glenn,

Your solution works great in most cases, but when I'm using it in FF with the Fields List initially hidden, the <br /> is ignored when I click the button and show it.  If I have the Fields List exposed on intial load, then the line break is respected, but if the Fields List hidden initially, then I see what's in the attached image.  Any ideas?

Thank you,

Dasha.
