Hi MaTaO,  

Greetings from Syncfusion support.  

Query: “ The aggregation only group and sum data at the current page, not all records in the data source” 

We understand that you want to display the total grouped count in aggregates based on the total records in a dataSource. Currently we do not have support for your requirement. We need some more details to analyze the feasibility in implementing this requirement. So kindly share the details about your grid data source details such as screenshot or code example. 

Regards, 
Renjith Singh Rajendran.

Hi Renjith,

Here is the screenshots base on Syncfusion.

page 1


page 2 


As you can see the group named "Condiments" has a total of 11 items in the data source that stay on a different page but the information in the aggregate template is the value of its page not the value of data source aggregation. What I want is an option to aggregate from the data source, not the page. Then display on the aggregation template. This might relate to the post: https://www.syncfusion.com/forums/148119/grouping-and-aggregate-display-group-key-in-ltgroupfootertemplategt due to I want to access to the key property in aggregation template in order to calculate from outside component then bind to the template with the mapping aggregation key.

I read the release note but did not find the related feature has been released.

Thanks

Hi Vignesh, is this still broken? I have this exact same need (using version 19.2.0.60) and setting DisablePageWiseAggregates="true" has no effect, I still see the totals per displayed page (kind of makes this aggregate feature useless).

Or is there a different way to accomplish this with the curre

Hi Gabriel,  
 
Thanks for contacting Syncfusion support.  
 
Query: “I have this exact same need (using version 19.2.0.60) and setting DisablePageWiseAggregates="true" has no effect, I still see the totals per displayed page (kind of makes this aggregate feature useless).” 
 
We have analyzed your query and we understand that you want to display the total records count in group caption aggregate. We suggest you to achieve your requirement using Lazy Loading Grouping feature. We have provided support for Lazy Grouping in our 2021 Volume 2 release. 
  
Kindly refer our online UG documentation and demo for your reference. 



Please get back to us if you have further queries or if above solution does not match your requirement.

Hello SyncFusion Team,

I'm experiencing the same issue with aggregation when using grouping in my Grid as the users mentioned above. However, LazyLoad is not satisfactory for me as I have a large amount of data. I tried to enable "DisablePageWiseAggregates", but it doesn't seem to work. Could I please ask for further support on this matter?

When I have page size on 50 rows and make a grouping with Lazy Load it groups the data well. But after I want to show the details of group, which is bigger than the page size, the aggregate doesn't show at all. 

Printscreen of OK and NOK behaviout attached (when number of records in group < page size -> OK) 

Thank you, Jakub

Hi Jakub,


Before proceeding with the reporting issue, we require some additional clarification from your end. Please share the below details to proceed further at our end.

  1. Please specify whether you are using local or remote data. If you are using remote data, which adaptor have you used?.
  2. Share with us the NuGet version you have used.
  3. Share us a grid code snippet with the model class.
  4. If possible, share with us a simple, reproducible issue.

Above-requested details will be very helpful in validating the reported query at our end and providing a solution as early as possible.

Regards,
Naveen P


JP Jakub Prosek April 4, 2023 09:03 AM UTC

Hello Naveen,

I'm sorry for a late reply, had a lot of work which has to be done ASAP. 

I use NuGet packages version 20.4.0.44 right now (going to upgrade to 21.1.38 next week)

In attachment there can be found almost the whole code of component with pseudonymized database access, there should be seen everything you asked for (data type, classes, settings of grid and also other functions).

There are the printscreen of different settings of "DisablePageWiseAggregates" as well on our data.

Thanks a lot for you help

Best regards

Jakub

Hi Jakcub


We would like to inform you that when you set the disablePagewiseAggregate setting to true,the aggregate values can be determined based on the current page. When you use disablePagewiseAggregate, you can show the total grouped count in the groupCaption. This only works for Remote data services. We would also want to inform you that the latest version of disablePagewiseAggregate is lazyLoadGrouping. We also prepared a simple sample in lazyloading; please give the following details about the issue you encountered when using Lazyloading so that we may validate it further at our end.


  1. Share us the entire Grid code snippet with loazyloading along with model class.
  2. Share us the video demonstration of the issue in provided sample.
  3. If possible share us an simple issue reproduceable sample or try to modify the above mentioned sample in pervious update
  4. If you have any screenshots or visuals for you requirement  that might help us understand better, please send those along too.



The above-requested details will be very helpful for us to validate the reported query at our end and provide the solution as early as possible


Regards,

Naveen Palanivel
