If you want to have DB2 populate
your Web page only with unique rows, you can select the Return only unique
rows check box.
11. Click Advanced. The Advanced
SQL Generation window opens.
12. Select the Generate
INSERT, UPDATE, and DELETE statement check box and click OK.
When you select this option, Visual
Studio 2005 will automatically generate the supporting SQL data manipulation
language (DML) for your DB2 database. Of course, you can do this manually as
outlined in the previous step. However, if you're not planning to customize any
of the default generated SQL, why not let Visual Studio 2005 handle it for you?
13. Click Next. The Test
Query window opens
14. Click Test Query to
preview the data that will be used to populate your Web page, and click Finish.
15. From the ToolboxData
section, drag the GridView object (used to represent a data grid) and
drop it just below the SqlDataSource object that you added in Step 5, as
16. Click the Choose Data
Source drop-down list and select SqlDatasource1 (the default name
assigned to the SAMPLE database's EMPLOYEE table that you configured in the
The data grid should be refreshed
and look like this:
You can see that Visual Studio 2005
has started to bind the data columns to the data grid. The data that's
displayed in the data grid are just place holders at this point and are used to
represent each column's data type.
17. You can configure some
automated usability features that Visual Studio 2005 can automatically add to your
Web page by clicking on the toggle at the right-most part of the grid view (if
it did not open automatically, or if you closed it). For this example, select the
Enable Paging, Enable Sorting, Enable Editing, Enable
Deleting, and Enable Selection check boxes, as shown below, and then
click anywhere in the data grid to return focus to the designer palette:
The GridViewTasks offers you
a lot of options for the way the data is displayed on your Web page. For
example, you can override what columns are displayed, their order, and so on,
and perform a number of operations such as those shown in the previous figure.
When you select any of these options, Visual Studio 2005 automatically adds
links for these actions to the data grid talk about easy!
You can see some of the results of
the actions from this step below:
You can see links have been added
to perform editing of data, deleting of data, and selecting of the data from
your Web page (provided you have these privileges on the tables you are
Also note the 1 2 links at
the bottom of the data grid. Visual Studio 2005 attached these to your data
grid because you selected the Enable paging option, which has the effect
of breaking down large result sets into multiple pages and providing these
controls to page through your query.
18. In the same manner in which
you dragged the DataGridView object to your designer palette, place a DetailsView
object (also located in the Data section of the Toolbox) just
below the DataGridView. The designer palette should now look like this:
19. Click Choose Data Source and
select the SqlDataSource1 object.
As you bound your DB2 data to your
data grid, you also have to bind the details of a selected row to this control object
20. Ensure that the options for
this object match the following figure:
You can see the designer palette
will bind a row to the details view and provide you with similar options as it
did in Step 17. Once again, if you look at the bottom of the previous figure,
you can see Visual Studio 2005 is adding controls to the Web page automatically
21. Press Ctrl+F5 to see
your Web site!
One of the great new features in Visual Studio 2005 is an
integrated application server hosting environment (based on IIS) that allows
you to quickly and easily test your Web applications. I love this feature and
DB2 can take advantage of it.
If you scroll to the bottom of your
Web page, you should see the controls added by Visual Studio 2005:
22. Play around with the
different links that were generated because of the options you selected for the
data grids. When you're finished, close the Web page, and stop the application
server, as shown below:
