Provides a way to determine whether a value is greater than or less than a specified value, or whether a value is between two specified values.

Gets or sets the field to use for the comparison.
Gets the data source object that is associated with the owner control.(Inherited from DataSourceExpression.)
Gets a value that indicates whether a data source expression object is tracking its view state changes.(Inherited from DataSourceExpression.)
Gets or sets the maximum value of the range.
Gets or sets the minimum value of the range.
Gets the owner control.(Inherited from DataSourceExpression.)
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
Serves as the default hash function. (Inherited from Object.)
|SetContext(Control, HttpContext, IQueryableDataSource)|
Executes the expression by using the specified owner control, context, and data source.(Inherited from ParameterDataSourceExpression.)
Returns a string that represents the current object.(Inherited from Object.)
When implemented by a class, loads the previously saved view state of the data source expression object.(Inherited from DataSourceExpression.)
When implemented by a class, gets a value that indicates whether a data source expression object is tracking its view state changes.(Inherited from DataSourceExpression.)
The DataField property to specify the column to search. You use the MinType property to specify whether to include or exclude the minimum in the search results, and you use the MaxType property to specify whether to include or exclude the maximum value. The maximum and minimum values can be specified in ASP.NET controls and the values can then be passed to the QueryExtender control as parameters in ControlParameter controls. The results are typically displayed in a data-bound control.class searches a data column using a pair of values that define the range. You use the
The following example shows how to search the ListPrice column in the Products table of the AdventureWorks database for products that have a list price in the range that is specified in the FromTextBox and ToTextBox text boxes. The filter includes the minimum value but excludes the maximum value in the results. The results are displayed in a Label control.
