Disabling the modification of columns based on another columns value

Hello,

I have a table in dataminer and I want to "grey" out a column based on data on another column of the same row.

i.e. if column 1 = true, column 2 is greyed out and cannot be modified by a user.

Is this something possible to do with in the xml, I know for QActions, Actions etc. it is possible via the "condition" statements but can't find something similar for things of type parameter.

Thank you,

Hi Ryan,

You can disable the write of a column base on the value of another column.

options attribute | DataMiner Docs

Let me know if this helps.

Does this work only on discreet? Is there similar function available for Datetime, and range bound parameters? I want to disable a datetime parameter when a toggle column is set to a value

It should work with all types of parameters—at least for the one you want to disable. In your case, you should be able to disable the DateTime parameter when the value of the toggle/discreet column is set to the desired value.

Thank you for confirming. I am trying with this parameter, can you see what I am doing wrong?

You are using "Scheduled" which is the <Display> for the value to match to then disable the write. Since your parameter is of type discreet you need to use the <Value> in your case 0.
Your options would look as follow.
<Type options="custom=disableWrite:18009=0">number</Type>

You only need to add this to the write parameter not the read.

Thanks, that's helped disableWrite parameters. The only problem I am having is while it disables the column, the change isn't displayed until I click somewhere in the screen. Do you know how to make this change appear by itself without any clicks?
