Dropdown control stops working

Hi All,

I have an SPO list where I have a bunch of drop down choice columns.  I created an APP and added them to the edit form.  When I play the APP from the designer, the drop downs work and show me the correct choices. 

After I pubish the APP, none of drop downs are working.

 

Any Ideas?

 

TIA,

Joe

@joef The fix for missing items in ComboBox drop-downs has been deployed to all production regions with Studio release 3.19101.  You will need to edit and re-publish your app(s) for the changes to take effect.

Re: Dropdown control stops working

Hi @joef ,

Could you describe more clearly about "none of drop downs are working"?

Does it mean that it doesn't display right default value or can not show the drop-down list or anything else?

If you could show me screen shoots about this problem, it will be better.

Re: Dropdown control stops working

HI @v-yutliu-msft ,

A few things happen. 

I go to edit the app, and I have red x's all over the place.  I have to refresh the data and all seems to be fine.  When I try to play the app from the designer, I click on a drop down and the arrow goes away and there are no choice.  I refresh the data again, and all the choices come back. 

I think all is fine so I publish the app.

I open the App either from my PC or my phone and the drowns do the same as I described above.

I have to republish the app to get everything to work properly.  Sometimes I have to close out of PA designer and reopen and publish again for the app to work.

 

I can't send any screenshots because all is working and I don't want to break anything 🙂

 

I fixed the defaults not showing by using:

If(EditForm1.Mode = FormMode.New,
{
Value:3
},
Parent.Default
)

 

Thanks,

Joe

Re: Dropdown control stops working

@joef We have recently committed a fix for a timing issue where ComboBox controls that are searchable can be unhooked from their data when the dependent data source is refreshed (or removed and added again).  

I'll re-post a mitigation that is currently recommended from this post: https://powerusers.microsoft.com/t5/Building-PowerApps-Formerly/Sudden-appearance-of-red-x-s/m-p/371...

 

As we understand it, the issue may occur sometimes when the data source that a ComboBox control is bound to is either (a) refreshed, or (b) removed and then added again.  The current advised mitigation that has seen success with customers is to perform the following actions after refreshing or removing/adding a data source:

  1. Save the app immediately and close it
  2. Re-open the app and continue making any non-data source refresh/remove/add changes (note: you will have to make at least one trivial change to mark the app as dirty so that it can be saved again in step #3)
  3. Save the app and re-publish

This should allow the ComboBox controls to be correctly reconfigured to the correct values.

Also, if your ComboBox control contains only a small number of values, it is advised to disable IsSearchable since (a) this incurs a slight overhead when enabled, and (b) the issue of empty values only occurs when IsSearchable=true.

 

FYI--the fix is expected to be deployed to all production regions the week of October 21.

Thanks @_Corey_ ,

Can't wait for the update :).  replacing cards in the middle of a large form is almost impossible...
