This topic describes how to enable and reset filtering for individual dashboard items.
To configure filtering in the Designer, select the target dashboard item and do one of the following.
If you are using a Ribbon menu, click the Edit Filter button in the Data tab.
Right-click a dashboard item and select Edit Filter from its context menu.
This will invoke the Filter Editor dialog. The dialog allows you to build complex filter criteria with a convenient tree-like interface. The bottom text panel can be used to enter filter expressions manually and provides syntax highlighting and autocomplete features.
Note that you can use hidden dimensions within the Filter Editor dialog, allowing you to filter data based on the values.
To clear the applied filter, select Clear from the dashboard item's context menu or click the Clear button in the Data Ribbon tab.
The following code shows how to apply filtering to a dashboard item in code. Note that the DataItem.UniqueId property is specified for Dimension objects to identify these dimensions in a filter string.
ChartDashboardItem chart = new ChartDashboardItem(); Dimension issueTypeDimension = new Dimension("issueTypeID", "IssueType"); Dimension productNameDimension = new Dimension("productNameID", "ProductName"); Measure openedMeasure = new Measure("Opened", SummaryType.Count); // ... chart.FilterString = "issueTypeID = 'Critical' And productNameID In ('Web Forms', 'Mobile')";
You can use the Filter Editor to filter a data source according to the current parameter value. To learn more, see the Passing Parameter Values topic.
You cannot apply filtering by building complex filter criteria in OLAP mode. Instead, you can filter dimension attributes and hierarchies by manually selecting the values you wish (or do not wish) to include in the dashboard.
For dimension attributes, the Filter Editor contains a list of all values.
For hierarchies, a tree is displayed instead, allowing you to filter individual values at any hierarchy level.
The filter expression contains logical operators that accept specified operands. You can use the following operands in filter criteria expressions.
The following criteria operators are supported in OLAP mode.
The binary operator only supports the BinaryOperatorType.Equal type.
The group operator can accept any of the supported operators with the following restrictions for data members from the OLAP data source (DataItem.DataMember).
