Dropdown control always resetting to first item

Posted on by Community Power Pla... Microsoft Employee

Hi,

 

I have a form with dropdown. I'm populating this dropdown from another list filtered by another dropdown value.

 

the problem is, on edit mode, it is always displaying the first item eventhough i set the default value to thisitem.<column> or parent.default.

 

the first load it is ok. but when i open another item the problem will happen.

 

Is there a caching bug here? if i wait for about 10sec before opening a new item, it is loading properly. 

 

please advise...

 

Thanks

    Hi @Anonymous,

     

    "I'm populating this dropdown from another list filtered by another dropdown value.", I'm not quite sure how did you achieve this. Could you please share more detailed configuration? Including how did you set the another dropdown value. Maybe some screeshots could help understand better. 

     

    Do mask sensitive data before uploading.

     

    Regards,

    Mona

    Hi @v-monli-msft,

     

    These are the steps:

     

    1. Department Field (Sharepoint single line of text) - in the powerapps form, i added a custom dropdown control in the datacard (Department_dropdown).

    2. in the Department_dropdown's "Items" property, i set it to Filter(<Departments Datasource>, Title=<dropdown2.selected.value>).Department. This will populate the department with items filtered by the dropdown2 selected.

    3. in the Department_dropdown's "Default" property, i set it to If (DisplayMode= DisplayMode.Edit, ThisItem.Department, Parent.Default)

     

     As you can see in the screnshots, the Department value should be PCG and not FCG. But the weird thing is that it doesn't happen all the time. it seems like the filtering was able to run but the setting of the default value didn't proceed.

     

    You can test this by creating multiple items, then try opening items quickly.
