I there a better way to handle try in C#

Question

I know that is generally expected that you should not swallow exceptions. In this code an Infragistic's UltraWinGrid is being configured. Is there a better way to handle the failed catch's are is this an exception to the rule?

 private void HideExcludedColumns(UltraGridBase grid)
        {
            if (_scExclusions == null) return;
            foreach (var strKey in _scExclusions)
            {
                //Set the appropriate column of the grid to hidden.
                foreach (var band in grid.DisplayLayout.Bands)
                {
                    try
                    {
                        band.Columns[strKey].Hidden = true;
                        break;
                    }
                    catch { }   //go to the next band.
                }
            }
        }

I agree with almaz - a blanket catch is bad juju in just about every case. Need to know what exception(s) wind up being there. If the column doesn't exist, there should be a better, non-exceptional way of doing that:

    private void HideExcludedColumns(UltraGridBase grid)
    {
        if (_scExclusions == null) return;
        foreach (var strKey in _scExclusions)
        {
            //Set the appropriate column of the grid to hidden.
            foreach (var band in grid.DisplayLayout.Bands)
            {
                var columnIndex = band.Columns.IndexOf(strKey);
                if (columnIndex > -1)
                {
                    band.Columns[columnIndex].Hidden = true;
                    break;
                }
            }
        }
    }

I'd introduce an assert in that catch block. That way whenever it gets entered during debug, the program will die and you can see what exception is being thrown. In production, the assert will not apply and the current behavior will remain. Then as you find exceptions being caught there, add code to handle them properly.
