Problem with hiding records in a grouping grid

[Rajesh John]

Hi,

In our application we are using syncfusion Grouping Grid control Version 3.3.
For the report, we are displaying group headers only. Those underlying records should not be expanded even though we click on expand button(+).
But unexpectedly after scrolling the grid, it is displaying the records.
Also sometimes the record row overlaps the next group header, hence the group header displays a blank row.
We used the property RecordAsDisplayElements = true for application performance improvement.
But if we set this property as FALSE after scrolling, it works fine.

Is there any alternate method to achieve this instead of setting RecordAsDisplayElements as FALSE?
Please find the attached screenshots.


Regards,
Rajesh

Hi Rajesh,

You would have to derive the Record and override the IsChildVisible() method. Below is a code snippet

public class GroupingRecordRow : Record
{
public GroupingRecordRow(Table parentTable) :base (parentTable)
{}
public override bool IsChildVisible(Element el)
{
this.InvalidateCounterBottomUp();
return false;
}
}

Please refer to the attached sample for implementation.

Here is a KB article that customize the child table/group by using a custom engine?
