Implementing a datagrid

Datagrids are the strong points of websheets. Websheets have been called 'Excel-killers'. If that is true, than datagrids are the weapons.

Getting ready

Make sure that there is a page available to implement the datagrid on. We can take the Sales overview page from the previous recipe and elaborate on that.

If you didn't create that page yet, do so before starting this recipe.

How to do it...

Let's say that the company in this example sells only one kind of product. They have no need for an elaborate database, so they would like a simple grid to monitor all sales.

When on the Sales Overview page, click the button on the right side called New Datagrid.
On the first page of the wizard, select the option From Scratch.
Next, enter the title and columns for the datagrid as shown in the following screenshot:
Click Create.
