The header of tree grid doesn't display correctly

[seanccc]

Hi, 

The header of the tree grid doesn't display correctly after the page get loaded .  Only after triggering data binding ,for example, by click a certain , then the header can display well .

Version: ThingWorx 8.4,  grid-advanced-4.2.0.

The service which is getting data for grid is being called on mashup load ? To see data on the grid on the page load you need to call the service on mashup load event .

Thanks ,

Hi @mnarang ,

The problem is the header , not the data inside the tree grid.  I bind the DataShape to the tree grid , the header display correctly in the design time , but doesn't display in runtime untill the service get the data.

It's a bit confusing ,generally we bind infotable data (coming from a service) to the grid which holds header and data both .And in design as well as in run time it display both without any issue .But as you said you mapped a data shape to the grid which displayed header in design time and then in run time it does not display until the data come from service .How exactly you have mapped the infotable data to the grid ?

@mnarang ，

Sorry for the confusing,  I mean my service has infotable as return type , and the infotable has datashape specified . I bind the all_data of my service to the tree grid. 

I just created a simple sample to reproduce the issue(see the attachment), it seems that only if the tree grid is embedded in Master then the tree gird doesn't display when loading the page the first time , but it display well if refresh the page .  Although the sample doesn't reproduce my issue completely,  the root cause could be same I guess .  Also , the issue is very similar with the case : https://support.ptc.com/apps/case_logger_viewer/auth/ssl/case=14836204,  which was created by me for the advanced grid.

Thanks for the detailed information ,I can see as per case comment it is reproducible on 8.4.1 . And Anna from support has sent you an older version of extension to test .Did you test on that as well ? 

We need to open this as a bug with R&D if it is reproducible .Will contact Anna for bug report and more details .

Thanks ,

@mnarang ,

I tried to switch to grid-advanced_4.1.1 according to Anna's suggestion,  the problem of the first time loading doesn't exist any more .   

However,  the original problem still exists , the header of the tree grid doesn't display the column names until trigger the service which bind to the tree grid ,  the advanced grid also has the same problem.   

Comparing with the grid widget,  it doesn't has the problem, it's head can display the column names well even if the service bound to it doesn't get triggered. (see the attached picture)

Hi Sean,

As we discussed, currently this issue was tracked by case in our Salesforce. We have requested Jira for the issue and as confirmed with R&D that this behavior is by design. For Advanced Grid use Grid instead to show header when no data is loaded. For Tree Grid currently there is no replacement widget.

Please understand and set this as solution to close this issue.

Thanks for your understanding!
