When working with Canvas apps, filtering large data sets is a crucial aspect to improve user experience. One intuitive way is by integrating an A-Z control for easier data navigation. This tutorial will guide you through implementing an alphabetical filter on a SharePoint-based data source in a Canvas app.
Importance of A-Z Filtering
Offering an A-Z control enhances user navigation, especially when displaying directories, be it lists of businesses, clients, or personnel. An alphabetical filter allows users to view records that start with their chosen letter, streamlining the search process.
Setting up the A-Z Control
Begin by adding a gallery control to your screen. Adjust its items property with the formula:
Sequence(26,65)
This formula generates a sequence of numbers representing the 26 letters of the alphabet, where 65 is the ASCII for ‘A’. Within the gallery control template, add a label and set its text property to:
Char(ThisItem.Value)
This conversion ensures the sequence number displays as the alphabet’s corresponding letter.
Applying the Filter
To showcase records starting with the selected letter, add another gallery control. For its items property, use the formula:
Filter(Client, StartsWith(Surname, galAtoZ.Selected.lblLetter.Text))
This filter function sifts through the client list, presenting records with surnames initiating with the chosen letter.
Enhancing the A-Z Control’s Look
Boost the A-Z control’s aesthetics by emphasizing the selected letter. For instance, change the label’s color upon selection using the formula:
If(ThisItem.Value=galAtoZ.Selected.Value, Blue, Black)
This conditional logic modifies the background color of the selected letter. Further, by configuring the label’s ‘Hover color’ property, you can make it visibly clickable.
Conclusion
Incorporating an A-Z filter in Canvas apps significantly enhances data navigation, particularly when dealing with extensive directories. With the steps outlined in this guide, you can effortlessly set up an alphabetical filter on your Canvas app integrated with a SharePoint data source. Remember, a seamless user experience leads to better app usability.
