Custom Paging and Hierarchical Data Source

Glayaar — Thu, 15 Apr 2010 23:30:35 GMT

You could analyze the provided WebGrid sample, BindtoHierchicalCustomObject.aspx, for the custom object hierarchical data in ISDataSource and WebGrid. Regarding the custom paging, the article titled "Walkthrough: Implementing Custom Paging using ISDataSource" in the WebGrid documentation already detailed Custom Paging and ISDataSource.

In both case above, you will only need to use IntersoftDataSource.

CustomFiltering and CustomSorting will be handled during server side WebGrid event handler as explained in these article "Walkthrough: Applying custom filtering in WebGrid" and "Walkthrough: Applying custom sorting in WebGrid" in the WebGrid documentation.

Custom Paging and Hierarchical Data Source

We use WebGrid.NET Enterprise 7.0.7200.

Our data has a hierarchical structure. As I understand from Intersoft documentation, the hierarchical structure is supported only when the WebGrid is bound to one of these types:

- System.Data.DataSet (this is what we currently use)

- Advanced Data Source Controls: XmlDataSource(partially supported) or IntersoftDataSource.

Our data can be very large in some cases and for performance reasons we need to implement the paging mechanism outside of WebGrid - our WebGrid would be bound to only one page at a time and therefore the size of its data would be limited (we would get better control over the response time and memory usage).

In order to achieve this, one option would be to enable WebGrid's Classic Paging and set the PagingLoadMode to Custom, but from what I understand from Intersoft documentation, the Custom Classic Paging is supported only when the WebGrid is bound to a DataSource Control.

Since we need both features, hierarchical structure and custom paging, we would need to bind the WebGrid to IntersoftDataSource.

My question is: if we need both features, is it correct that we have to use the IntersoftDataSource, or we could also use System.Web.UI.IHierarchicalDataSource for example?

We also need to use Custom Filtering and Custom Sorting, for the same performance reasons. What is the answer in this case?

Thanks.
