QUESTION
I have a "Phone-book" and with a login panel. After a user logs in, they can add their phone numbers.
The part I am having trouble with is trying to add new functionality allowing users to delete their phone numbers from the database.
...ANSWER
Answered 2021-Nov-13 at 21:14You should add a column like user_id. and save the id of the user who added the phone number. so after that you can check if the logged user id is equal to the user_id then it can be deleted
QUESTION
I have referred to this blog for listing the phone contacts. Also, I have implemented adding contacts to the phonebook using DependencyService as per this thread.
My problem is after adding a contact to the device phone book I need to fetch the entire latest contacts. Also, I need to show the new contact on the contact listview.
For reference, I have created a sample project and uploaded it here. In this sample first of all I am listing the phone contacts with the Add New option on the top. If we tap Add New, a new page will open with the Add to Contact option and entry for phone number. Click the Add to Contact option after entering a phone number, then the device phonebook page will show with the phone number entered.
At this stage, the user may or may not save that number to the device phonebook. So when the user resuming to the App I need to fetch the entire contacts and check the phone number is added or not to the device phone book. If contact added I will hide the Add to Contact option else I will show that option again. At the same time when the user going back to the contact list, I need to show the newly added contact over there.
For this, I have added a message on App.xaml.cs and Subscribe it on AddContactPage.

QUESTION
I have an array that has 3 contacts. I want the same person's name to be deleted when I click on the delete button, but unfortunately I do not know where the problem is that it does not work.
I have two functions in this program, one removeContact to perform the delete operation
And I have a function called showrecords to get the content of the array and display the name and number of contacts with a dedicated delete button for each contact
In this program, I used the pattern builder pattern
Please guide me to the conclusion to solve the problem of not being deleted
Please click on the show Person button to test the program. Contacts will be displayed and click on the delete button. You will see that the delete operation is not performed.

QUESTION
I am having issue where i need to have update Multiple Mobile no's , Landline no's and Emails , websites , address in local phonebook contact.
If contact is already exist in phone book then i am trying to update it's details.
Below is the code i am trying. It is getting executed without error but no multiple mobile no , landline , email etc not reflecting in phone-book on that contact as the multiple data's are their.
I also referred few of the links but that didn't helped as well.
...ANSWER
Answered 2020-May-11 at 08:38- one issue that can be either a bad parameter name, or an actual bug is that your selection is requesting a
RAW_CONTACT_IDand supplying a parameter calledcontactId, I'm not sure what is stored incontactIdbut there's a big difference between arawContactIdand acontactId, so if that's indeed a contactId your operations will not find anything to update (or even worse, update the wrong contact). - The second issue is that your two loops (over
userInfoMobileNosanduserInfoGmails) keep updating (overriding) the same Data row, so eventually you should end up with just the last value in the contact details. You're also not checking if there's a Data row in the contact details that fit your selection, if there's not, there will be no row to update, and therefore the code will simply do nothing. - Third issue, but it may be intentional, not sure how you expect your app to work, is that you assume the info item type, i.e. you only update a phone if it's TYPE_MOBILE, and you only update the email if it's TYPE_WORK, what if there are other phones and emails stored for that contact? your code will simply keep those untouched, not sure if that intentional or not.
To fix issue one, just make sure the value in contactId is a RawContactId and change the name of the param.
For the second issue, you should instead do a delete-and-insert, see code below.
For the third issue, you'll need to change the selection code (paramsMobile) to remove it's assumption of label.
Here's suggested code:
