The Year function displays the year for a particular date. =DateAdd(DateInterval.Month, 6, Parameters!StartDate.Value) The following expression provides a date that is six months after the date from a parameter named StartDate. The DateAdd function is useful for supplying a range of dates based on a single parameter. Here are some valid DateInterval parameters:įor example, this expression will show the number of the week in the current year for today's date: =DatePart(DateInterval.WeekOfYear, today()) Use the DateInterval function to pull out a specific part of a date. This expression can be used in a text box to display the date on the report, or in a parameter to filter data based on the current date. The Today function provides the current date. For example, to round 1.3 to the nearest multiple of 0.2, which is 1.4, use the following expression: =Round(1.3*5)/5 Multiply the value by a factor that creates an integer, round the number, and then divide by the same factor. You can also write an expression to round a value to a multiple that you specify, similar to the MRound function in Excel. The following expression rounds 1.3 to 1: =Round(1.3) The Round function is useful to round numbers to the nearest integer. For more information, see Formatting types. NET Framework provides many custom format options, for example, for specific date formats. For more information, see Visual Basic runtime library members on MSDN. This section provides examples demonstrating some of these functions. You can use Visual Basic functions to manipulate the data that's displayed in text boxes or used for parameters, properties, or other areas of the report. You can also use classes from the Microsoft. You can add references to functions in custom code. You can write expressions that use functions from the Microsoft Visual Basic runtime library, and from the xref:System.Convert and xref:System.Math namespaces. You can format data, apply logic, and access report metadata using these functions. Many expressions in a report contain functions. Parameters: Examples for using parameters in an expression.Ĭustom code: Examples of embedded custom code.įor more information about simple and complex expressions, where you can use expressions, and the types of references that you can include in an expression, see Expressions in Power BI Report Builder. Properties: Examples for setting report item properties to control format or visibility. Report functions: Examples for aggregates and other built-in report functions.Īppearance of report data: Examples for changing the appearance of a report. Visual Basic functions: Examples for date, string, conversion, and conditional Visual Basic functions. This article provides examples of expressions that can be used for common tasks in a report. Expressions begin with an equal sign (=). Expressions are written in Microsoft Visual Basic, and can use built-in functions, custom code, report and group variables, and user-defined variables. Expressions are used frequently in Power BI Report Builder paginated reports to control content and report appearance.
