Power Apps - Canvas Apps

1. Welcome

Congratulations on finishing the Data Watch and Security section. Now let's move on to power apps.

2. Creating First Power Apps Application

In this lecture we'll talk about variables, collections, and components. So this is related to examobjective, implementing variables and collections. So there are three types of variables: local variables, global variables, and collections. The scope of local variables is limited to one screen. The scope of a global variable is for the whole application, and collections are also for the whole application. This is how you define a local variable. You just write: "update context, variablename, and the variable value." If it's a string, then you put it in code if it's a number. If it's not a string, then you put the number. You can use a function of blank to reset the value of the variable. Similarly, to set a global variable, you use the variable name and variable value and again use blank to reset the value. So let us have a look at it. If you go to file variables, you will see that we have a local variable here and it is using Update Context. Now let us define a global variable. So let us say we define this global variable here and we go back to file variables. So this browse screen one on browser one is sorted descending as a local variable, and we have a global variable called variable Name that we just defined. Now coming to collections, this is how you define a collection. You say? Clear. Collect. This is the name of the collection, and then in each record you have two fields named "name" and "email field name and email.And then you have two records, name one and name two. Then you use Collect if you want to add to the collection. So if you want to add name three to this collection of names one and two, you can use the Collect function to remove a particular row. You use remove if the collection name and then you give what you need to remove. The clear function will empty the collection. If you want to convert a collection into a string so that you can display it properly, then you can use the Cat function. This is a variable named concat, which tells you how to make a string out of it. So you have full name, open braces, email, and closes, and this is Cat, which is essentially a newland corrector, so it will separate the two records within the collection. So let us have a look at it. So we'll define a collection of ice cream that will have two values: flavour and quantity. So let us put it there, then go to file instead of variables, we'll go to variables, go to collections, and you'll see I have a collection of ice cream with flavour and quantity. So that was all about variables and collection. Now let us talk about components. So if you go to Power Apps and go to Apps on the Apps tab, you have apps as well as componentlibraries where you can create a new component. You can also go to your application and on preview you have components here where you can add a new component or you can import or export a component. You can also go to insert and incustom and you will have the same option of newcomponent, import component, or export component. Let us create a component from here, say a test component. A component is basically a group of UIobjects with certain properties set, which you can use again and again in your applications. So here I have created a component and then it will give me an area. And here I can add or add a label here I can add a button here. I can move it around, set values, and then save it and use it in multiple places. So, these are the screenshots for our reference. We have a component library here on the main apps page and then on the editor. Also, we have component step as well as custom. We can use these options. So we learned about variables, collections, and components in this lecture. Thank you. Bye.

3. Updating Power Apps Application

In the last lecture, we created a sample PowerApps app. Now let us make some changes to it. So this is the app we made and you can click here and click on Edit to make changes to it. And it will take you to this clip. Now, as you said, there are three screens. Browse screens where you see everything. details screen where you see all the details of one item. and edit screen to make changes. Now on top, you have a menu, and you can insert a new screen. These are various types of screens. A label, a button, text feeds like label, textinput, HTML, which text pen input like a button,text pen, drop down a form, edit format, displayform, any media, various charts, various icons. We have this plus icon here. And we see this plus icon. Same here. custom components. Gallery and mixed reality On the left hand side, you have the screens. Middle portions are interviewed to see the UI and write his properties. Now let us make some changes to it. Now instead of a description, I want to see the price. So instead of overview, I will say price and I will see the price. At this price, I want to put a dollar sign. So instead of price, I'll say I'll put in a dollar sign. So you see, we have signed. Now we have a dollar sign. Now if all of them were black in color, So if the price is more than $5, then I want to show it in a red color, otherwise a green color. So I click here and here. If I go to colour, I can say if this item's price is greater than five, then color, right? Otherwise, now you see we have red if the price is more than five and green if it is less than five. So these are all the events, and these are all the functions for that event.So let us go over there. So we have already seen this added dollar signand change the text colour based on the item's cost. We have added formatting to prices and added logic for color. Then if you click on "plus here", you can add an item. And this is to change the sorting order. So if I run this, this is to change the sorting order. And this is to add an item. It is using an edit form. If I go to browse green, I can clickon plus, and I can see the lot. So how you add a form is you create a new form of the type, edit this one, edit this screen one. This is the first edit form. And now we get to the edit screen. And how do you change the sorting? You simply update contacts to not the existing sort in descending order. So this is what we have here. Add new form creates a new form and updates the sorting. So this is the UI. You can see all the screens here. These are all the events, and this is the corresponding function. And these are the properties we use this function. This is the name of the column. And we can use this function to change the column name. So we changed that from description to price. And this is our browsing thing. The name of this icon is plus new item one. We saw this one. This is the next arrow one. And this is the browse gallery. So this is the new icon new item one.new item icon, item one. This is the next arrow one. So if I click on this one, the next tarot one. And the programming is selectparent then browse gallery one. This is a browse gallery. This is the whole list of items then on display if I want to change the order of the items. So what I have to do is I have to click here and edit fields, let us say image. I want to skip to the end. So I just dragged it to the end and you see, it has gone to the end. So this is our new display. So I can always play it and see if it has gone to the end. So this is, again, not the browser screen. A detail screen on a detail screen I have this edit. This is the icon-edit one. I can edit one. This is a data charge one.See, this one is a data charge one. So a data card is basically a control card control.So each card represents a single field of the record. So in this case, it shows the flooring category from the floor estimate table. And this whole thing is detailed from day one. So this detail form one is the whole form. So we used all this to add new controls to the screen. And then this is when we saw how to edit fields. So suppose in the edit form for overview, we want to change it to multiline text. If you go back to the edit screen, if I go to editfield and overview, I want to edit text to multi-line text. Seeing it becomes a little bigger, so we have more space to enter the overview field. If I play it, you'll see I have a little more space here. So again, this is an accepted one. So we submit the form on I can accept one and then the data card. This is data card two. And then this is the edit form. This whole thing is in edited form. We saw these fields. So there are a few controls that can add interest and impact to your applications. including forms to show details about your data. and create and edit record media to add images. Include camera button barcodes and readercharts to add charts. Galleries are layered containers that hold a set of controls that show records from a data source. This is all the options available in the menu which we see. So here we have covered that we have made some basic updates to the custom application which we created and customised as per our requirements. Thank you.

4. Versions & Sharing

In this lecture, we'll talk about version sharing. Let's get back to the app. So if I click on my application and click on details here, I can see other versions, and for any other versions, I can either delete them or restore them. Once I restore it, it creates a new version. It will create a new version for version four. And once we are editing the app, if we go to File and Settings here, I have the option to change the name, icon, and description of the application. Then on the application, I can also share it with other users or groups. And we have two kinds of permission: user permission or co-owner permission. So we have a share and we can see details. We can add people as users and co owners.And we have to make sure the data connection has also been shared. So, on the Share tab, specify the user groups with whom you want to share the application in order to add everyone in your organization, by typing everyone and selecting everyone in the company name. And if you want to share your application with a group, it is preferred that you use your Active Directory security group to share it. Now, we talked about two permissions: coowners and users. Users can only view the applications their co-owners can edit, share and collaborate on the applications, but they cannot delete or change the owner of the application. Now, consider this Suppose I have given read-only permission to a group and within that group I have one person to whom I have given co-owner permission. So that person will have co-owner permission. But if we do it the other way around, I have given a co-owner permission and within that group, one person has user permission. Then that person will have coroner's permission because we will give him the greatest permission. This is the versioning screen. So when you restore a version, the newly restored version gets a new incremented version number and appears at the top of the list. A new version never overrides the previous version. This is all just now. We also saw that if you go to File Settings, we can edit and give it a meaningful name, item, and description. Thank you.

5. Variables, Collections & Components

In this lecture we'll talk about variables, collections, and components. So this is related to examobjective, implementing variables and collections. So there are three types of variables: local variables, global variables, and collections. The scope of local variables is limited to one screen. The scope of a global variable is for the whole application, and collections are also for the whole application. This is how you define a local variable. You just write: "update context, variablename, and the variable value." If it's a string, then you put it in code if it's a number. If it's not a string, then you put the number. You can use a function of blank to reset the value of the variable. Similarly, to set a global variable, you use the variable name and variable value and again use blank to reset the value. So let us have a look at it. If you go to file variables, you will see that we have a local variable here and it is using Update Context. Now let us define a global variable. So let us say we define this global variable here and we go back to file variables. So this browse screen one on browser one is sorted descending as a local variable, and we have a global variable called variable Name that we just defined. Now coming to collections, this is how you define a collection. You say? Clear. Collect. This is the name of the collection, and then in each record you have two fields named "name" and "email field name and email.And then you have two records, name one and name two. Then you use Collect if you want to add to the collection. So if you want to add name three to this collection of names one and two, you can use the Collect function to remove a particular row. You use remove if the collection name and then you give what you need to remove. The clear function will empty the collection. If you want to convert a collection into a string so that you can display it properly, then you can use the Cat function. This is a variable named concat, which tells you how to make a string out of it. So you have full name, open braces, email, and closes, and this is Cat, which is essentially a newland corrector, so it will separate the two records within the collection. So let us have a look at it. So we'll define a collection of ice cream that will have two values: flavour and quantity. So let us put it there, then go to file instead of variables, we'll go to variables, go to collections, and you'll see I have a collection of ice cream with flavour and quantity. So that was all about variables and collection. Now let us talk about components. So if you go to Power Apps and go to Apps on the Apps tab, you have apps as well as componentlibraries where you can create a new component. You can also go to your application and on preview you have components here where you can add a new component or you can import or export a component. You can also go to insert and incustom and you will have the same option of newcomponent, import component, or export component. Let us create a component from here, say a test component.

We have a component library here on the main apps page and then on the editor. Also, we have component step as well as custom. We can use these options. So we learned about variables, collections, and components in this lecture. Thank you. Bye.
