Multi Person People Picker control in SharePoint list forms customized via Power Apps behaviour

 

Today i ran into a weird issue. I had a People picker control on my SharePoint list form. Just to give you a background of my situation. i am customizing a SharePoint list forms using Power Apps. Yes, it totally sucks, but client is the king and specially when you have government client.

Problem: Client wanted to have a column, lets say "Follow Project" which will be a people picker column. This column will be used for following a particular project, on which they may not be working on but are interested in. Also not to forget the higher executive, who randomly wants to check a project.

Solution: i created a people picker column in SharePoint and added it to my Power Apps customized SharePoint form. i quickly tested the functionality and i was able to save, view and edit the person value.

But then i realized that let me make it more flexible so as instead of users groups can also be added. Also, why not enable multiple person. All this looked out of the box, so i went to my SharePoint list. Clicked on the respective column and made both these changes.


Now when i tried to again test the solution, i was able to add multiple values. But guess what i wasn't able to save it and of course not retrieve it. So i decided to check the power app form. And to my surprise the field had started giving me error. The default property was no longer taking in the selected items instead of selected.


So i started looking for new solutions, old fixes, MS released notes. But no luck. finally i ended up in a discussion where someone suggested that this happens as People picker control is tightly coupled to forms and even after the fix released my MS if you change the column values after you have already created the column you Datacard will get corrupt and start giving errors. Easiest fix is to delete the column create a new people picker column, along with all the specific settings enabled like multiple values and people and groups enabled. Add the respective field to the form. Don't forget to refresh your data connection. And voila every thing will start working. Just documenting this behavior so as it saves someones else time.

Creating Nested Galleries in Power Apps. (Parent-Child Relationship)

Image
 This is another most common scenario where in client has two parent child lists or any two lists having a common SharePoint column. And clients wishes to have a relationship on the PowerApps screen where in when he/she selects a particular lets say Program in our example. All the respective Projects following that Projects are shown. In such a scenario we can leverage nested galleries. So what we do in here is we add two galleries on our Power App screen. For Programs gallery the Left one on the screenshot above, we connect it to the Programs list For Second gallery we will connect it to the Projects list. But this is where the magic happens. Here we use Filter () function. So what we do in here is we set the Program's column value in Project's list equal to the Selected Program of left Gallery. i.e. the gallery connected to my Program's list. A more complex version of the same is where you inset the nested gallery inside your parent gallery. In this too everything remains

How to reset a datepicker control in PowerApps?

Image
 Scenario: Simple reset a date picker control. Issue, you can't use normal Reset() function to reset the datepicker control. Solution: Simple create a variable Set(varResetCD, True) and use this variable to update the reset property of DatePicker control. The below Reset() won't work in case of datepicker control We need to create a variable and use it at the Reset property of the datepicker control. Also, if you still see some text inside your date field there are two other places you need to check in one is the datepicker control advanced properties. In the above screenshot all you need to do is clear InputTextPlaceholder. And then select the control and check the DefaultDate property of the date.  This should be set to Today(), you can also change it to something like below If(varResetCD,Blank(),Today()) What this does is sets the control to blank if the variable you have declared above is true.

 Hi Good day, Today we have a very interesting scenario. We have a cascading dropdowns on our Power App screen. The flow for these dropdowns is that a user selects the Division, and a list of Business units containing the selected Division is popped down in your Business Unit dropdown. Now to make it user friendly, we have on change code written on each dropdown. So that if the user decides to change the Division dropdown, the Business Unit dropdown is reset. Please remember in here we are talking in regarding to New Form. On Resetting the above Division combo box, since we have written the Reset function code on Change property of the Division Combo box.   Reset(ddBU);Reset(ddBPI);Reset(ddTeams). The above becomes Up till here everything is hunky dory. This is the classic case of how the Reset() function should behave. But that's not, when you move from new form to Edit form.   The Reset function behaves weirdly. It is able to reset the cascading dropdown values like above. But i
