When you enable caching for the SqlDataSource control, you cache the results of the SelectQuery. However, if you create a select query that takes parameters, the SqlDataSource will cache a separate result for every set of parameter values. For example, imagine you create a page that allows you to view employees by city. The user selects the desired city from a list box, and you use a SqlDataSource control to fill in the matching employee records in a grid (see Figure 26-8). Figure 26-8.

In this example, each time you select a city, a separate query is performed to get just the matching employees in that city. The query is used to fill a DataSet, which is then cached for up to ten minutes (600 seconds). If you select a different city, the process repeats, and the new DataSet is cached separately. However, if you pick a city that you or another user has already requested, the appropriate DataSet is fetched from the cache (provided it hasn t yet expired). sans-serif; Figure 6-13. Setting the DataBound event for a DropDownList 7. Add the following code to the DataBound event: protected void lstManufacturers_DataBound(object sender, EventArgs e) { ListItem myListItem = new ListItem(); myListItem.Text = "please select..."; myListItem.Value = "-1"; lstManufacturers.Items.Insert(0, myListItem); } 8. Modify the code within the lstManufacturers_SelectedIndexChanged event handler as follows: protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { if (lstManufacturers.SelectedValue != "-1") { // code as it stands at the moment } default). That s because the DataReader object can t be efficiently cached, because it represents a live connection to the database. Caching separate results for different parameter values works well if some parameter values are used much more frequently than others. For example, if the results for London are requested much more often than the results for Redmond, this ensures that the London results stick around in the cache even when the Redmond DataSet has been released. Assuming the full set of results is extremely large, this may be the most efficient approach. On the other hand, if the parameter values are all used with similar frequency, this approach isn t as suitable. One of the problems it imposes is that when the items in the cache expire, you ll need multiple database queries to repopulate the cache (one for each parameter value), which isn t as efficient as getting the combined results with a single query. If you fall into the second situation, you can change the SqlDataSource so it retrieves a DataSet with all the employee records and caches that. The SqlDataSource can then extract just the records it needs to satisfy each request from the DataSet. This way, a single DataSet with all the records is cached, which can satisfy any parameter value. To use this technique, you need to rewrite your SqlDataSource to use filtering. First, the select query should return all the rows and not use any SelectParameters: generate code 128 barcode in c# Code 128 Barcode Generator for Microsoft Visual C# .NET
