Hello

Just testing the new PivotGrid and a few features seem missing which may be critical and I cannot see an easy way to customise via templates or the like.
Apologies in advance if I have just missed it in the documentation or my understanding.

In my opinion, the main purpose a developer would put a PivotGrid into a web application;

• To simplify data "slicing and dicing" for users not comfortable with tools such as Excel/PowerBI, and reduce the need to export to Excel.
• To synchronise a pivotGrid view with other components/controls and/or charts on the page

 

Critical

1. No width parameter: This seems quite critical for general formatting purposes
2. No mouse hover: Considering there is no width parameter, then there should at least a mouse hover so that the user can hover to see content which has been cut-off due to insufficient width (like the TelerikGrid).
3. Defer Layout Update: By default the telerik PivotGrid is always deferring the layout change. Usually on PivotGrids (Excel / PowerBI) there is a tick-box to allow the user to choose. For performant pivot tables, there is no need to defer the layout allowing for quick anaytics.
4. No "Title" attribute or alias for xmla fields: There is no property to rename fields in the xmla dataset, so the user needs to see the full [Table].[ColumnName] attributes in its raw form (which ends up being quite ugly and potentially confusing for the user).
   eg: <PivotGridRow Name="[Product].[Category]"></PivotGridRow>
5. No event handlers: I cannot see any event handlers at all on this control? There are many user-triggered events which could be triggered within the GridConfigurator. This would be critical to synchronise the PivotGrid with any other controls, with the PivotGridEventArgs holding data of what was modified and if the modification was made to the PivotFields or Measures.
6. No state management: Cannot save or restore state of GridConfigurator. Potentially, the user may have spent some time setting up their perfect PivotGrid that suited their needs, hence saving state seems critical.
7. No programmatic control via @ref="PivotGrid": Cannot programmatically control the PivotGrid. This would be important to enable synchronisation between other Telerik controls / items on the page.

 

Less Critical

1. Export: Not critical but some form of export (Excel/PDF), to allow user to save the results.

 

Aside from that, all good and works well.

The component struggles to update Local data source when it changes. I have bound it to a value, but when that value changes it is not reflected in the UI.

The issue occurs when you update the data with an entirely new collection. Calling Rebind afterwards does not help either.

A possible workaround for the time being is to dispose and re-initialize the component when the new data arrives. Here is an example: https://blazorrepl.telerik.com/cHFlaNOg49AjRPUl19.

I'd like to be able to set width to the columns to ensure the data inside them will be visible. Similar to https://docs.telerik.com/kendo-ui/api/javascript/ui/pivotgrid/configuration/columnwidth.

I am binding the PivorGrid to local data and I am validating that the list contains some records. However, the PivotGrid appears empty. It looks like if the data arrives after PivotGrid initializes, the component does not display it.

A possible option to handle the scenario for the time being is to ensure the PivotGrid initializes only when the data is available. For that purpose, you can conditionally render the component based on the data count. Optionally, you can show a LoaderContainer while the data is being fetched.

Here is an example that showcases the approach: https://blazorrepl.telerik.com/cdujObbF15YVdqvR54.

In the PivotGrid there are two "GRAND TOTAL" labels. When using localization only the one on the row is translated. The column Grand total label is not translated.
