How to use IF formula, filter, and sort a gallery in PowerApps

In PowerApps, the IF formula, filter, and sort features are incredibly useful for managing data in a gallery. In this article, we'll take a closer look at each of these features and show you how to use them effectively.

Using the IF formula

The IF formula is used to test whether a condition is true or false. If the condition is true, a specified value or formula is returned. If the condition is false, another specified value or formula is returned. To use the IF formula, follow these steps:

1. Select the control that you want to apply the formula to.
2. In the formula bar, type the following formula: If(condition, true_value, false_value)
3. Replace 'condition' with the expression that you want to test. In my case is use the IF formula for the ascending and descending order of a workers data in gallery.
4. Replace 'true_value' with the value or formula that you want to return if the condition is true.
5. Replace 'false_value' with the value or formula that you want to return if the condition is false.
6. I use the following formula.

?If(SortDescending1, SortOrder.Descending, SortOrder.Ascending)

Filtering a gallery

Filtering a gallery allows you to display only the items that meet certain criteria. To filter a gallery, follow these steps:

1. Select the gallery that you want to filter.

2. In the formula bar, type the following formula: Filter(datasource, condition)

3. Replace 'datasource' with the name of the data source that you want to filter.

4. Replace 'condition' with the expression that defines the filter criteria, In my case i use the filter for starts with Title.

Filter([@'Worker Directory-RM'], StartsWith(Title, TextSearchBox1.Text)

Sorting a gallery

Sorting a gallery allows you to display the items in a specific order. To sort a gallery, follow these steps:

1. Select the gallery that you want to sort.
2. In the formula bar, type the following formula: Sort(datasource, column, ascending/descending)
3. Replace 'datasource' with the name of the data source that you want to sort.
4. Replace 'column' with the name of the column that you want to sort by.
5. Replace 'ascending/descending' with the sorting order that you want.
