Hi Bernhard, 

 

Thank you for your interest in Syncfusion products. 

 

The GridGroupingControl does not have any built-in support to hide the summary row for child tables alone. However, this can be achieved by avoiding the child table expanding at run time for the tables that have empty records. We already have provided a KB document to achieve this use case. Please make use of the below KB link for further details.

Please let us know, if we misunderstood your requirement.

I'm sorry, but unfortunately this is not working out the way I would like it to.

to show all groups already opened I use the following method

grdAnzeige.GetTable("tblNation").ExpandAllRecords();

If I set an empty group to "static" with the given function, without the above method only the headline of the group is displayed.
However, when I use ExpandAllRecords(), column headers and group total are still displayed.

This is not what I wanted.
In my opinion, this is not useful either.

How can I turn it off?

Hi Bernhard, 

 

Thank you for the update. 

 

We could understand the scenario and the GridGroupingControl does not have built in support to remove the child tables when it has 0 records. However, the reported scenario can be handled by using the RecordExpanding event. Please make use of the below sample code for further details. 

 

Example code 

 

//Event subscription 

this.gridGroupingControl1.Table.RecordExpanding += Table_RecordExpanding; 

 

private void Table_RecordExpanding(object sender, Syncfusion.Grouping.RecordEventArgs e) 

{ 

    //To restrict the expand when the records are expanded programmatically. 

    if (e.Record.NestedTables.Count > 0 && e.Record.NestedTables[0].Records.Count == 0) 

    { 

        e.Cancel = true; 

    } 

} 

 

Please let us know, if you have any other queries.
