Hi Varjang I'm using the following test :new List(of string) from {"aa","bb"} but I got everything double in dropdown like aa bb aa bb any Idea? thanks in advance

[@carlorobazza7569]

After the state and city values have been selected, where are the selected values stored? Are they only in the JSON output? When using select boxes, etc., the selected values are updated in the dictionary. Is it different for drop-down lists? Thanks!

[@vajrangorg]

There might be changes in implementation, please post it in uipath fourm

[@ElWiwif]

You rock man!

Thank you

Hi Vajrang, what should I do if I need to populate the text box instead of two dropdowns

There's undocumented feature to execute the Do block: instance.emit('executeDoBlock', instance.component); But for me the problem is I don't know how to create this on dropdown select change condition

[@maxim.pechura]

I'm attempting the following: const updateOnChange = instance.updateOnChange; instance.updateOnChange = function(flags, changed) { if (flags.modified) { instance.emit('dropdownChanged', 'drop'); instance.emit('executeDoBlock', instance.component); } return updateOnChange.call(instance, flag, changed); }

[@vajrangorg]

This might work

[@AshishParjapat]

used this code , but have a problem, the dropdown always shows the last value of the list when the form is loaded, and when i change the value in dropdown, it revert back to the original one which is the last item of the list , and the it shows the log message two times const updateOnChange = instance.updateOnChange; instance.updateOnChange = function(flags,changed){ if(flags.modified){ instance.emit('dropdownChanged','drop'); } return updateOnChange.call(instance,flags,changed); }

[@vajrangorg]

Think form is getting reset after change

[@AshishParjapat]

@@vajrangorg may be but have one more issue , i created a list ={india,USA,Russia} the dropdown is auto populated with Russia

[@emili84848]

I have the same issue. The solution was to type _dropdown on the variable name in the form collection

Hi Vajrang Could you please help me with the below scenario For example if I select the State as Goa and city as Margo then if I change the State to Madhyapradesh how to make the city dropdown value Margo to be removed and appear to have only Madhya Pradesh cities

@@vajrangorg how to achieve this on Multiple Select drop down . I could see previous selected option as well . If I changed the selected drop down.

I have been looking for a solution for a week. Can the same be done for textField? After entering, for example, 3 characters in the textField field, the Do Forms loop looks up the value from the database. Do you know how you can fire up Do loops from fieldText Change? If you know please help.

[@vajrangorg]

you need to enter text and use any button to trigger do block in form else you cannot do that and you can write code in do block of the form

[@philipstv7341]

@@vajrangorg Thank you for your response. I thought it could be done without a button. It would be very, very cool. Too bad: /

Hi Mate Could you maybe post a working project on the uipath community forums? A bit hard without working example. But this dropdown is exactly what I was after.

[@vajrangorg]

Sure will do it

[@martincoronado8829]

can i use the js code inside a datagrid?, two drop down inside of the datagrid

[@vajrangorg]

Yes you can try

[@angelquinz]

If I choose multiple values to be selected in Dropdown, how can I limit it to only 10 values selected?

[@HP.0]

Hello, Were you able to figure this out? if yes, what was the solution?

[@angelquinz]

@@HP.0 wasnt able to figure this out. What I did is i put validation in button properties where it will only show when they put values < 11 :) hope this helps.

[@HP.0]

@@angelquinz ok got it, thanks for a quick reply.

[@vajrangorg]

Hope this got resolved

[@philipstv7341]

You have any errors in JavaScript. Did not work.: const updateOnChange = instance.updateOnChange; instance.updateOnChange = function(flags,changed) { if(flags.changed) { instance.emit('dropdownChange','drop'); } return updateOnChange.call(instance,flag,changed) }

[@vajrangorg]

Yes I did initially pause video at final code that's the correct one

[@vajrangorg]

6:00 shows you correct code
