Exercise - Add controls to display data
Adding the data doesn't mean that your users can view it in your app. You need to add a control to display it. Two main controls that display repeating rows of data are the data table and the gallery.
Decide how to display your data
Data tables are useful in that they can quickly display data in a way that appears similar to a Microsoft Excel spreadsheet. The disadvantages are that you can't edit data or do many customizations, even on individual columns (such as allowing various column widths). A gallery is much more customizable. You can include buttons to take actions on specific lines of data and format fields exactly the way that you want them. The drawback to using galleries is the larger effort in creating and customizing them. Also, you can't scroll both horizontally and vertically because galleries only allow one or the other.
For this solution, you use a gallery because you're customizing the view beyond what a data table allows and will take action on your data.
Add a gallery
To add a gallery, follow these steps:
Ensure that you are on Scr_AllExpenses, select the Insert tab on the ribbon, and then select the Vertical gallery from the dropdown menu.
After inserting your gallery, you can view several lines of placeholder data. Similar to the image, you need to point the gallery to the correct data.
Select the Data source dropdown menu on the Properties pane and then select Expense Reports.
Rename your gallery to Gal_ExpenseReports_AllExpenses.
Your gallery is currently empty. You add data soon so that you can observe what happens. In the meantime, you know that expense reports won't need an image, so you can update the layout of your gallery.
In the Properties pane, select the Layout dropdown menu and then select Title and subtitle.
Let's save the app before continuing further. Look for the Save icon in the top right of your screen ribbon and select it.
While Microsoft Power Apps will save every two minutes, it's a good idea to save frequently. One reason is that you can add version notes after development milestones to track your progress. You can restore a previous version if some major errors occur. Furthermore, you never know where you are in the two-minute cycle and should save in case a problem arises with your internet or computer.
