MBDataTable<TItem>

Summary

A partial implementation of a Material Data Table built using render fragments. It features:

Details

• A Table Header render fragment, which requires correct HTML/CSS markup for the table's header;
• An IEnumerable of Table Row render fragments, also requiring correct HTML/CSS markup; and
• Applies density subsystem.

Assisting Blazor Rendering with @key

• MBDataTable renders similar table rows with a foreach loop;
• In general each item rendered in a loop in Blazor should be supplied with a unique object via the @key attribute - see Blazor University;
• MBDataTable by default uses each item in the Items parameter as the key, however you can override this. Material.Blazor does this because we have had instances where Blazor crashes with the default key giving an exception message such as "The given key 'MyObject' was not present";
• You can provide a function delegate to the GetKeysFunc parameter - we have used two variants of this:
  • First to get a unique Id property that happens to be in our item's class: GetKeysFunc="@((item) => item.Id)"; and
  • Second using a "fake key" where we create a GUID to act as the key: GetKeysFunc="@((item) => Guid.NewGuid())".
  • You can see an example of this in the MBList demonstration website page's code.
