Analysis Filter - Filtering with Query String Parameters

Special reserved query string parameters can be used to manipulate the Analysis Filter.

Remove all Filter Definitions

All filter definitions can be removed by calling the report with the rdAfReset parameter set to True.

In the example above, a Label has been added to a report as a link that clears all filters. The Target.Report element is set to Current Report and the Link Parameters element is used to pass the rdAfReset parameter.

Force a Page Refresh with Current Filter Values

You can force a complete page refresh by calling the report with the rdAfRefresh parameter set to True.

Define a New Filter

You can define and apply a new filter by sending a full set of query string parameters. The parameters are:

rdAfCommand="FilterSet"
rdAfFilterColumn_<AnalysisFilterID>="<ColumnName>"
rdAfFilterOperator_<AnalysisFilterID>="<Operator>"
rdAfFilterValue_<AnalysisFilterID>="<FilterValue>"
rdAfMode_<AnalysisFilterID>="<ViewMode>"
rdAnalysisFilterID="<AnalysisFilterID>"

where:

• <AnalysisFilterID> is the ID of an existing Analysis Filter element in the report being called
• <ColumnName> is the name of a column that has an Analysis Filter Column element configured for it
• <Operator> is one of the operators available in Design view
• <FilterValue> is the data value on which to filter the column
• <ViewMode> specifies the filter display mode to be used, Simple or Design

If one or more filters already exist for the specified column then when these parameters are applied, the value of the first existing filter will change. An additional filter will not be created.

Here's an example for comparison purposes, using the XML source for these parameters defined in a Link Parameters element. They're based on the filter examples used in Analysis Filter - Using the Analysis Filter Elements:

<LinkParams
rdAfCommand="FilterSet"
rdAfFilterColumnID_<AnalysisFilterID>="CustomerID"
rdAfFilterOperator_myAnalysisFilter="="
rdAfFilterValue_myAnalysisFilter="VINET"
rdAfMode_myAnalysisFilter="Simple"
rdAnalysisFilterID="myAnalysisFilter"
/>

To make the code dynamic, tokens can be used to provide values for the parameters:

rdAfFilterValue_myAnalysisFilter="@Request.FilterOnThis~"
