CreateDataSourceSelectArguments Method

DataBoundControl.CreateDataSourceSelectArguments Method

Creates a default DataSourceSelectArguments object used by the data-bound control if no arguments are specified.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

'Declaration
Protected Overridable Function CreateDataSourceSelectArguments As DataSourceSelectArguments

The CreateDataSourceSelectArguments method is used by the SelectArguments property to initialize a default arguments object, and by the DataBoundControl class's implementation of the PerformSelect method.

The following code example demonstrates how the CreateDataSourceSelectArguments method can be used in a derived class to retrieve a default DataSourceSelectArguments object.

    Protected Overrides Sub PerformSelect()

        ' Call OnDataBinding here if bound to a data source using the  
        ' DataSource property (instead of a DataSourceID) because the  
        ' data-binding statement is evaluated before the call to GetData. 
        If Not IsBoundUsingDataSourceID Then
            OnDataBinding(EventArgs.Empty)
        End If 

        ' The GetData method retrieves the DataSourceView object from the  
        ' IDataSource associated with the data-bound control.            
        GetData().Select(CreateDataSourceSelectArguments(), _
            AddressOf OnDataSourceViewSelectCallback)

        ' The PerformDataBinding method has completed.
        RequiresDataBinding = False
        MarkAsDataBound()

        ' Raise the DataBound event.
            OnDataBound(EventArgs.Empty)

    End Sub 'PerformSelect
