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.

C#

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')";

VB.NET

Dim chart As New ChartDashboardItem()
Dim issueTypeDimension As New Dimension("issueTypeID", "IssueType")
Dim productNameDimension As New Dimension("productNameID", "ProductName")
Dim openedMeasure As New Measure("Opened", SummaryType.Count)

' ...

chart.FilterString = "issueTypeID = 'Critical' And productNameID In ('Web Forms', 'Mobile')"
