Enable/disable radionbuttons in datawindow
Ian Brouwer
I have a datawindow with a column being displayed as a number of
readiobuttons (the column edit style type = RadioButtons).
Under certain circumstances, I need to disable some radiobuttons so they
appear 'ghosted' and the user cannot select it.
Could someone tell me if this is possible and if so, please provide the
syntax.
Thanks in advance.

bitmap that looks like the command button except grayed out and making
it visible over the command button.

string ls_modstring
ls_Modstring = + &
as_ColName + ".radiobuttons.3D=NO " + &
as_ColName + ".radiobuttons.scale=YES "
dw_1.Modify( ls_modstring )
To enable that same column, flip the NO's and YES's.

I basically use Paul's approach but execute this through an SQL computed
column (acting as a switch) and placing expressions on the RB's that
interrogate the CC's state and set the various properties accordingly. This
saves allot of external DW Control code like Paul has shown you. However,
either technique achieves the same end result.
Food for thought.

We created a function in the ancestor datawindow - uo_EnableCol( string as_colName, boolean ab_Enable)
The code I showed is in the function, and it handles all the other edit styles as well. So our application code only
has to call:
dw_1.uo_EnableCol( 'myColumn', TRUE ) - to enable, and vice versa to disable.
That saves having to code extra controls into the datawindow itself. More food for thought... ;)

Thanks for the tip, except the example disabled the 'column' instead of one
of the radio buttons for 1 of the values for that column.
Example:
The column name is 'Status' which can contain the values 0, 1 or 2.
So in normal circumstances 3 radio buttons for this column will be enabled
and displayed.
In certain circumstances I want all radio buttons to be visible, but only
enable the radio buttons for the values 1 and 2, and disable the radio
button for the value 0.
Can anyone help we this one ?

I would add two computed columns to the select statement:
...
0 as three_choice,
0 as two_choice,
FROM
...
Set each of these up as radio buttons - the first with all three choices, and the second with only two (I don't think
there's a way to display the third as disabled). Don't even put the original column on the dw surface. Then toggle the
visible attribute for these two to display the one you want and hide the other. Use the ItemChanged event to do
SetItem( row, "original_rb_column", data ) when either of the two "fake" columns are changed.

Another good implementation for sure!

Radio button edit style for the column is a poor choice - it
is just a code table presented in a funky way/ The code
table is common for the column in ALL the rows.
Use a dddw edit style either with:
1) Easier - visual indicator that n of the choices are not
suitable combined with scripting in the itemchanged that
disallows their choice
2) Harder - creative conditional filtering of the dddw
