+# Data Binding Modes
+
+The Report Designer works in one of the following data binding modes:
+
+* **Expressions** is the default binding mode.
+
+    This mode enables you to specify complex [expressions](../use-expressions.md) that include two or more data fields, [report parameters](../shape-report-data/use-report-parameters.md), or [functions](../use-expressions/expression-syntax.md). You can also use expressions to [calculate summaries](../shape-report-data/calculate-summaries/calculate-a-summary.md) of any complexity or [conditionally shape your data](../shape-report-data/specify-conditions-for-report-elements.md).
+
+    Click a property's marker to see whether the invoked context menu has the **PropertyName Expression** item that invokes the **Expression Editor**.
+
+    ![Property Marker](../../../../images/eurd-win-binding-modes-property-marker.png)
+
+    The **Expression Editor** allows you to use functions, access report bands and controls, and reference data source values in the constructed expression.
+
+    ![Expression Editor](../../../../images/eurd-win-binding-modes-expression-editor.png)
+
+* **Expressions Advanced** is the advanced Expression mode.
+
+    This mode enables you to specify an expression that is evaluated within a control's specific event.
+
+	![property-grid-expression-advanced-tab](../../../../images/eurd-win-binding-modes-expressions-advanced.png)
+
+    The **Expression Editor** allows you to use event argument values in the constructed expressions. Event arguments are available in the [Variables](../use-expressions/expression-syntax.md) section.
+
+    In the **BeforePrint** event, you can use data fields from all queries in the data source.
+
+    ![Expression Editor for the BeforePrint event](../../../../images/eurd-win-binding-modes-data-fields.png)
+
+    In the **PrintOnPage** event, data source fields are not available because data was fetched when this event occurs. You can use the event arguments that are available in the [Variables](../use-expressions/expression-syntax.md) section.
