Show, sort, and filter data in a PowerApps gallery
Create a gallery to show images and text about several products, and sort and filter that information.
In PowerApps, you can use a gallery to show several related items, just as you see in a catalog. Galleries are great for showing information about products, such as names and prices. In this topic, we create a gallery and sort and filter the information using Excel-like functions. Also, when an item is selected, a border is placed around the item.
This topic uses a tablet app. You can use a phone app but you will need to resize some of the controls.
- Sign up for PowerApps, and then sign in using the same credentials that you used to sign up.
- Create a tablet app from a template, from data, or from scratch.
- Learn how to configure a control.
- These steps use the CreateFirstApp as sample input data, which includes .jpg images. The zip file includes an XML file that can be converted to Excel. Otherwise, PowerApps automatically reads the files in the .zip files and imports it successfully. You can download and use this sample data, or import your own.
Show data in a gallery
Create a collection named Inventory using the sample data. Steps include:
On the Insert tab, select Controls, and then select Import:
Set the OnSelect property of the import control to the following formula:
- Select the Import Data button to open Windows Explorer. Select CreateFirstApp.zip, and select Open.
In the File menu, select Collections. The Inventory collection is listed with the data you imported:
You've just created the Inventory collection, which contains information about five products, including a design image, the name of the product, and the number of units in stock.
The import control is used to import Excel-like data and create the collection. The import control imports data when you are creating your app, and previewing your app. Currently, the import control does not import data when you publish your app.
- Select the back arrow to return to the designer.
On the Insert tab, click or tap Gallery, and then click or tap the Horizontal gallery.
In the right-hand pane, click or tap the option in which the title and the subtitle overlay the graphic:
Set the Items property of the gallery to Inventory:
Rename the gallery to ProductGallery, and move the gallery so it doesn't block the other controls. Resize the gallery so it shows three products:
In the first item of the gallery, select the bottom label:
When you change the first item in any gallery, you automatically change all other items in the gallery.
Set the Text property of the label to the following expression:
When you do this, the label shows the units in stock for each product:
By default, the Text property of the top label is set to
ThisItem!ProductName. You can change it to any other item in your collection. For example, if your collection has ProductDescription or Price fields, you can set the label to
Using these steps, you imported data that includes .jpg images into a collection. You then added a gallery that displays the data and configured a label to show the units in stock for each product.
Highlight the gallery item you select
- Select any item in the gallery except the first one. The edit icon displays (upper left corner). Select the edit icon:
- On the Insert tab, select Shapes, and then select the rectangle. A blue solid rectangle appears in each gallery item.
- On the Home tab, select Fill, and then select No Fill.
- Select Border, select Border Style, and then select the solid line.
- Select Border again, and set the thickness to 3. Resize the rectangle so that it surrounds the gallery item. The items in your gallery now have a blue border and should look similar to the following:
On the Shape tab, select Visible, and then enter the following formula in the Formula Bar:
A blue rectangle surrounds the current selection in a gallery. Select a few gallery items to confirm that the rectangle appears around each item that you select. Remember, you can also open Preview to see and test what you're creating.
Select the rectangle, select Reorder on the Home tab, and then select Send to Back. Using this feature, you can select a gallery item without the border blocking anything.
Using these steps, you added a border around the current selection in the gallery.
Sort and filter items in the gallery
In these steps, we are going to sort the gallery items in ascending and descending order. Also, we'll add a slider control to 'filter' gallery items by the units in stock that you choose.
Sort in ascending or descending order
- Select any item in the gallery except the first one.
The Items property is currently set to Inventory (the name of your collection). Change it to the following:
When you do this, the items in the gallery are sorted by the product name in ascending order:
Try descending order. Set the Items property of the gallery to the following formula:
Sort(Inventory, ProductName, Descending)
Add a slider control and filter items in the gallery
- Add a Slider control (Insert tab > Controls), rename it to StockFilter, and move it under the gallery.
Configure the slider so that users can't set it to a value outside the range of units in stock:
- On the Content tab, select Min, and then enter the following expression:
- On the Content tab, select Max, and then enter the following expression:
- On the Content tab, select Min, and then enter the following expression:
- Select any item in the gallery except the first one. Set the Items property of the gallery to the following expression:
- In Preview, adjust the slider to a value that's between the highest and the lowest quantity in the gallery. As you adjust the slider, the gallery shows only those products that are less than the value you choose:
Now, let's add to our filter:
- Go back to the designer.
- On the Insert tab, select Text, select Input Text, and rename the new control to NameFilter. Move the text control below the slider.
- Set the Items property of the gallery to the following expression:
Filter(Inventory, UnitsInStock<=StockFilter!Value && NameFilter!Text in ProductName)
- In Preview, set the slider to 30, and type the letter g in the text-input control. The gallery shows the only product with less than 30 units in stock and has a name with the letter "g":
Tips and Tricks
- At anytime, you can select the preview button () to see what you created and test it.
- When designing your app, you can re-size the controls and move them around using click-and-drag.
- Press ESC or select the X to close the preview window.
- When using a gallery, select the first item in the gallery to change all items in the gallery. For example, select the first item to add a border to all items in the gallery.
- To update the properties of the gallery, select any item in the gallery except the first one. For example, select the second item to update the Items, ShowScrollbar, and other properties that apply to the gallery (not the items in the gallery).
