<para>The <see cref="T:System.Web.UI.WebControls.AccessDataSourceView" /> class is intended primarily to be used by data-bound controls and not as a programmable object in page code.</para>

<para>The <see cref="T:System.Web.UI.WebControls.AccessDataSourceView" /> object overrides the <see cref="M:System.Web.UI.WebControls.SqlDataSourceView.ExecuteSelect(System.Web.UI.DataSourceSelectArguments)" /> method to ensure that the <see cref="P:System.Web.UI.WebControls.AccessDataSource.DataFile" /> property of its associated <see cref="T:System.Web.UI.WebControls.AccessDataSource" /> control is set before retrieving data. </para>
|
|
<para>Before the <see cref="M:System.Web.UI.WebControls.AccessDataSourceView.ExecuteSelect(System.Web.UI.DataSourceSelectArguments)" /> method is performed, the <see cref="M:System.Web.UI.WebControls.SqlDataSourceView.OnSelecting(System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs)" /> method is called to raise the <see cref="E:System.Web.UI.WebControls.SqlDataSourceView.Selecting" /> event. You can handle the <see cref="E:System.Web.UI.WebControls.SqlDataSourceView.Selecting" /> event to examine the values of the parameters and to perform any preprocessing before a data retrieval operation.</para>
|
|
<para>To perform the data retrieval, the <see cref="T:System.Web.UI.WebControls.AccessDataSourceView" /> object builds an <see cref="T:System.Data.IDbCommand" /> object using the <see cref="P:System.Web.UI.WebControls.SqlDataSource.SelectCommand" /> text and any associated <see cref="P:System.Web.UI.WebControls.SqlDataSource.SelectParameters" /> properties. Then, the <see cref="T:System.Web.UI.WebControls.AccessDataSourceView" /> object executes the <see cref="T:System.Data.IDbCommand" /> object against the underlying data storage. After the operation completes, the <see cref="M:System.Web.UI.WebControls.SqlDataSourceView.OnSelected(System.Web.UI.WebControls.SqlDataSourceStatusEventArgs)" /> method is called to raise the <see cref="E:System.Web.UI.WebControls.SqlDataSource.Selected" /> event. You can handle the <see cref="E:System.Web.UI.WebControls.SqlDataSource.Selected" /> event to examine any return values and error codes and to perform any post-processing.</para>
|
|
<para>If the <see cref="P:System.Web.UI.WebControls.SqlDataSource.DataSourceMode" /> property is set to the <see cref="F:System.Web.UI.WebControls.SqlDataSourceMode.DataSet" /> value and caching is enabled, the <see cref="T:System.Web.UI.WebControls.AccessDataSourceView" /> retrieves data from and saves data to the cache during the data retrieval operation. The cache is created, discarded, or refreshed, based on the caching behavior that is specified by the combination of the <see cref="P:System.Web.UI.WebControls.SqlDataSource.CacheDuration" /> and <see cref="P:System.Web.UI.WebControls.SqlDataSource.CacheExpirationPolicy" /> properties.</para>
|
|
<para>If the <see cref="P:System.Web.UI.WebControls.SqlDataSource.DataSourceMode" /> property is set to the <see cref="F:System.Web.UI.WebControls.SqlDataSourceMode.DataSet" /> value and a <see cref="P:System.Web.UI.WebControls.SqlDataSourceView.FilterExpression" /> property has been specified, the <see cref="P:System.Web.UI.WebControls.SqlDataSource.DataSourceMode" /> property is evaluated along with any supplied <see cref="P:System.Web.UI.WebControls.SqlDataSourceView.FilterParameters" /> properties and the resulting filter is applied to the list of data during the <see cref="M:System.Web.UI.WebControls.SqlDataSource.Select(System.Web.UI.DataSourceSelectArguments)" /> operation.</para>
