DataBoundControl.CreateDataSourceSelectArguments Method

Definition

Namespace:

System.Web.UI.WebControls

Assembly:

System.Web.dll

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

C#

protected virtual System.Web.UI.DataSourceSelectArguments CreateDataSourceSelectArguments();

Returns

DataSourceSelectArguments

A DataSourceSelectArguments initialized to Empty.

Examples

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

C#

protected override void PerformSelect() {            

   // Call OnDataBinding here if bound to a data source using the
   // DataSource property (instead of a DataSourceID), because the
   // databinding statement is evaluated before the call to GetData.       
    if (!IsBoundUsingDataSourceID) {
        OnDataBinding(EventArgs.Empty);
    }            
    
    // The GetData method retrieves the DataSourceView object from  
    // the IDataSource associated with the data-bound control.            
    GetData().Select(CreateDataSourceSelectArguments(), 
        OnDataSourceViewSelectCallback);
    
    // The PerformDataBinding method has completed.
    RequiresDataBinding = false;
    MarkAsDataBound();
    
    // Raise the DataBound event.
    OnDataBound(EventArgs.Empty);
}

Remarks

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.
