Вообще для DW:
либо
this.Describe("<Columnname>.Protect")
или
this.Object.<Columnname>.Protect

НО ИМХО, так как свойво protect установить для строку нельзя, то без
дополнительного поля, значение которого и будет опряделять изменение цвета, не обойтись.

Если возможно как нить по другому, то я с радостью приму к сведению.

Но вот:

These properties are set per column and can only be changed on a per row base by
declaring an expression for the properties.

For instance, if you want to change the color based on something unrelated to the
data in the datawindow you will need to add a hidden computed column/field, and set
the background color of the desired column to be based on the value in the computed
column/field. Then just set the value in the computed column/field for that row, to
set the color of the desired column for that row.

I'm afraid there's no way to automate this but please find below a do-it-yourself
w/a which is our solution:

1* Create a new tabular dw which SQL select is:
SELECT emp_fname, emp_lname
FROM employee

2* Add two computed fields in the footer band called CF_ROW and CF_COL
Expression for CF_ROW is 0, expression for CF_COL is ""
3* Set the footer height to 0 to hide the computed fields
4* Select emp_fname in the detail band
5* Enter an expression for the desired property (e.g., Font Background Color)
6* Enter:
If (GetRow()= cf_row and string(cf_col) = "emp_fname", RGB(192,192,192), RGB(255,
255, 255))

//You have to do this for all columns for any property
7* Select emp_lname in the detail band
8* Enter an expression for the same property
9* Enter:
If (GetRow()= cf_row and string(cf_col) = "emp_lname", RGB(192,192,192), RGB(255,
255, 255))

10* Place the dw inside the dw control on a sheet
11* Add the window a singlelineedit control called SLE_1, an editmask EM_1 and a
command button CB_1
12* Regarding the editmask, set its mask to ## and check the spin property
13* Add the following code to CB_1 clicked event:
dw_1.object.cf_row.expression = em_1.text
dw_1.object.cf_col.expression = "'"+sle_1.text+"'"

14* Run the application
15* Type in SLE_1 a value for the column: either emp_fname, or emp_lname
16* Use the EM_1 spin to increment the row value
17* Click CB_1
=> The new background color will only concern the designed column.

This shows you that you can modify a property w/o altering the whole column or row
so now you can remove controls from the sheet and store their values in variables.
No other way.
