Conditional disply

Question

Have a drop down list of 5 items (Group1-5), one text field to enter associated no that pertains to each group, then sql report will fire up based on the input
1. how do you make this text fied to be a conditional display: ie. This text field should not show up unless user click one of the drop down item. I tried "request is containied within express 1" and type express1 as &P_ item in ('group1','group2'...'group5') . But this is not working
2. When the text field is displyed , I would like to have the data mask come up that already prefix the input field. For example : group1 use GP1xxxx, group2 use WK2XXX ....
Can u give me some pointers ? thanks.

Hi Zen,
To do both (that group2 WK2XXX messed it up a bit) you'll first need to change your LOV. Include your prefix as the return value e.g.:
STATIC2:group1;GP1,group2;WK2 etc. You also want your LOV to Display null (so clicking Yes).
With your text field you want it's conditional display to be:
Value of Item in Expression 1 NOT NULL
and Expression 1 to be your LOV item e.g. P_ITEM (no colon).
To get the value into this text field you then need to alter the text field Source
Source Used: Always, replacing any existing value in session state
Source Type: Item (application or page item name)
P_ITEM (no colon).
This example is with the idea that P_ITEM is the name of your LOV...change if not. Under the Element section of the text field set the maximum width to whatever you want it to be e.g. 8 for 8 characters long. I don't know about masking but if you just wanted the XXX displayed then you could just have the return value to be like: STATIC2:group1;GP1XXXXX,... problem with that is that the X's won't overwrite the user would have to delete them before entering new values.
imo this is ok for your problem (providing you ignore my stupid solution to the XXX mask) generally though...initial part prepared, limited to the fixed code length, only displays when a value is selected etc.
