In this last post, we discussed the PowerApps templates. Now, in this post finally, we are going to create our first PowerApp, isn’t it exciting?
So, as mentioned earlier, login with the authorized credentials and after login, you will find the following dashboard screen. Here, we need to select a Blank Template as shown below. Here, we have a choice to opt for mobile or desktop web. We can choose as per your ease or requirement and then press make this App button.
After clicking the make this app button, we get the following screen which is basically our playground for App creation or actual editor where we can manage our pages, add new pages, add controls, etc.
As this is our first app, we are going to make it very simple and create an addition of 2 numbers screen (although, it seems simple but a bit tricky as well.)
For which we will click 3 label controls, 3 textboxes & 1 button and arrange them properly as shown in the below figure. Here, we can change the control’s default text, color, etc. by property pane.
Once this part is done, in the next step, we need to show the sum of First Number, Second number’s value in 3rd text box when user clicks the Sum button.
One more point which we need to take care of is format property of the textbox.
Now, to achieve this, we are going to write a function on button click as shown in the below image:
Here, we need to write the code in function’s tab as shown below in the screen. If you see here, we are using a SUM inbuilt function and using UpdateContext (an internal function) for assigning the addition value of the textboxes to a variable called myAdd.
Now, once we are done with the above function, in the next step, we are going to assign the myAdd variable (who holds the addition of text1 & text2) to our result text box. To achieve this, select the textbox in which we need to show summation value & click on the Property window’s function tab.
Here, we have to assign the myAdd variable as a data’s default value (shown in the below figure).
Once we are done with the above steps, the next item would be to run this App and do a quick testing. To run this App, click on run button (top right corner of the editor) as shown in the below figure:
We will get the below screen to test our sum logic.
That’s great! We created and tested our first PowerApps. Now, in the next step, save this application. After clicking File menu, a new screen (as we are saving this first time) will appear where we need to provide App name, description of app and icon. After providing these details, click on the Save menu.
So, congratulations! We have created our first simple PowerApps and saved successfully.
We will see later how to publish it which is also a very easy step.
In the next article, we will see more stuff of PowerApps. Till then, enjoy!
