Sort( IceCream, Quantity, SortOrder.Descending ) The Quantity column contains numbers, so the table is sorted numerically. The Flavor column contains strings, so the table is sorted alphabetically. For example, specify "Column Name" as "Column_x0020_Name".įor the following examples, we'll use the IceCream data source, which contains the data in this table: If multiple ColumnNames are supplied, all but the last column must include a SortOrder.įor SharePoint and Excel data sources that contain column names with spaces, specify each space as "_x0020_". SortOrder.Ascending or SortOrder.Descending. SortB圜olumns( Table, ColumnName1 )ĬolumnName(s) - Required. SortOrder.Ascending is the default value. Specify SortOrder.Descending to sort the table in descending order. You can reference columns within the table. This formula is evaluated for each record of the table, and the results are used to sort the table. See the delegation overview for more information. What is available in the Gallery may not be the complete story, which could be confusing to users. Filter and sort functions will operate on a reduced set of records. If delegation is not possible, Power Apps will pull down only a small set of records to work on locally. The delegation list details which data sources and operations can be delegated. When possible, consider changing the formula to avoid functions and operators that can't be delegated. If complete delegation of a formula isn't possible, the authoring environment will flag the portion that can't be delegated with a warning. Data sources vary on what functions and operators they support with delegation. However, delegation may not always be possible. The result is a faster start time for the app and access to very large data sets. As the user scrolls, additional data is brought down from the data source. For example, when you start an app that shows a Gallery control filled with data, only the first set of records will be initially brought to the device. When possible, Power Apps will delegate filter and sort operations to the data source and page through the results on demand. See working with tables for more details. Sort and SortB圜olumn don't modify a table instead they take a table as an argument and return a new table that has been sorted. They can be passed to and returned from functions. Tables are a value in Power Apps, just like a string or number. Records found that do not appear in the sort table are put at the end of the list. All records which have Monday" will come first, followed by Tuesday, and so on. For example, you can sort record based on the name of a day of the week by supplying as the sort order. In addition to sorting ascending or descending, SortB圜olumns can sort based on a single column table of values. You can combine SortB圜olumns with a Drop down or List box control to enable users to select which column to sort by. For example, SortB圜olumns( CustomerTable, "LastName" ). Column names are specified as strings, requiring double quotes if directly included in the parameter list. Sorting is performed in the order of the parameters (sorted first by the first column, then the second, and so on). The parameter list for SortB圜olumns provides the names of the columns to sort by and the sort direction per column. The SortB圜olumns function can also be used to sort a table based on one or more columns. For example, you can use this formula to sort a Contacts table first by a LastName column and then by a FirstName column: Sort( Sort( Contacts, LastName ), FirstName ) To sort first by one column and then by another, you embed a Sort formula within another. For more information, see the examples below and working with record scope. The As operator can also be used to name the record being processed which can help make your formula easier to understand and make nested records accessible. Use the ThisRecord operator or simply reference fields by name as you would any other value. The formula must result in a number, a string, or a Boolean value it can't result in a table or a record.įields of the record currently being processed are available within the formula. The formula is evaluated for each record of the table, and the results are used to sort the table. The Sort function sorts a table based on a formula.
