How to make particular value in field Read Only from dropdown list ?

[Ridhi5EA5]

Hi,

I am having 2 Dropdown DP1 and DP2.

the values of DP1 is A,B,C and DP2 value is E,F,G

if i select the 'A' from DP1, in DP2 value shld be 'E' and the remaining values ('F' and 'G') should be greyed out automatically.

if i select the 'B' from DP1, in DP2 value shld be 'F' and the remaining values ('E' and 'G') should be greyed out automatically.

if i select the 'C' from DP1, in DP2 value shld be 'G' and the remaining values ('E' and 'F') should be greyed out automatically.

i know how to make the whole field read only, but here i am asking like the particular value in drop down alone should be read only not a whole drop down.

Could any one please help me on this.

You can't set readonly some entries of the dropdown. At validation of the dropdown you can reject selected entries.

You can't grey out items in a drop-down. As mentioned, you can use a script to reject certain selections, but a much better option is to change the actual list of available items in the drop-down to just those values that you want the user to select from.

Could you please provide the script to reject certain selections of dropdown.

As the custom validation script of the drop-down you can use something like this:

if (this.getField("DP1").valueAsString=="A" && (event.value=="F" || event.value=="G")) {
	app.alert("The selected value is not allowed.");
	event.rc = false;
}

Just use caclulation script in "DP2" field

if(this.getField("DP1").valueAsString == "A")

event.value = "D";

use 'else if' to add other combinations.

Even if you try select other values it won't change.

@Asim123 

event.value pointing to DP1 aor DP2?

[Asim123]

It points to DP2 field,

if DP1 value is A DP2 value will be D.

@Asim123 

You mentioned like "Just use caclulation script in "DP2" field"

Could you pls provide me the script, i m new to this adobe script.

[Asim123]

I gave you script for A value now just write 'else'  (whitout quotes) and paste my script again and just change values form A to B and D to E and repeat again for last combination.

[Ridhi5EA5]

var field_dp2=this.getField('dropdown2');

var field_dp2=this.getField('dropdown3');

var fieldScript="switch (event.value) {

case 'A': 

field_dp2="E";

field_dp3="H";

break;

case 'B':  

field_dp2="F";

field_dp3="I";

break;

case 'C': 

field_dp2="G";

field_dp3="J";

break;

 }

Will this script work for 3 drop downs?

[Ridhi5EA5]

Based on value of dropdown1, dropdown2 and dropdown3 value gets populated.

[Ridhi5EA5]

@Asim123 this script will work
