Grouping grid summary rows are not getting refreshed

[Sachin Bamel]

Hi

I recently migrated from syncfusion 2.1.0.9 to syncfusion 4.2. I am having an issue with grouping grid with 4.2. My summary row is not getting refreshed and I am not seeing real time update of summary rows as well as grouped rows. This used to work fine with older version. With the analysis it seems to me that the refresh of summary rows dont happen when the rows are collapsed but it works fine when rows are expanded. Can somebody please help.

Thanks,
Sachin

Hi Sachin,

This can be resolved by calling the refresh method in the CurrentRecordContextChange event. Please try this code snippet and let me know if this helps.

this.gridGroupingControl1.CurrentRecordContextChange += new CurrentRecordContextChangeEventHandler(gridGroupingControl1_CurrentRecordContextChange);

private void gridGroupingControl1_CurrentRecordContextChange(object sender, CurrentRecordContextChangeEventArgs e)
{
if (e.Action == CurrentRecordAction.EndEditComplete)
{
e.Record.InvalidateCounterBottomUp();
this.gridGroupingControl1.Refresh();
}
}

For more details refer to broswer sample ( \\windows\Grid.Grouping.Windows\Samples\CustomSummary )

Hi Haneef,

we are already implementing the event CurrentRecordContextChangeEventHandler mentioned by you . But this event will get called only when user navigate to a different tab . In our case

if( e.Action == CurrentRecordAction.NavigateComplete )
{
OnCurrentRecordChanged();
}


In our application user will not edit in the grid as is seen in your sample, but instead the model gets updated in code real time & we need to refresh the summary. This used to be working fine for 2.1.0.9 but it dont work for 4.2. Non summary rows are getting refreshed correctly . Also as mentioned earlier if the grouping grid is collapsed in that case the summary gets refreshed properly.

I am attaching the 2 files from code which implements the grouping grid.

Thanks,
Sachin

I observed that when I click on column header to sort, my summary starts getting refreshed. Any idea what is the reason for it.

Hi Sachin,

By default, the summaries should be refreshed as you leave the row (not the cell). If you want the summaries updated as you leave the cell , you can add a CurrentRecordContextChange event handler, and trigger the actions there.

private void grid1_CurrentRecordContextChange(object sender, CurrentRecordContextChangeEventArgs e)
{
if(e.Action == CurrentRecordAction.CurrentFieldChanged
|| e.Action == CurrentRecordAction.EndEditComplete )
{
this.gridGroupingControl1.CurrencyManager.EndCurrentEdit();
this.gridGroupingControl1.Table.SummaryDirty = true;
this.gridGroupingControl1.Table.TableDirty = true;
this.gridGroupingControl1.Table.InvalidateSummary();
}
}

To update the summaries as you change the underlying datasource, Please refer to the below form thread.

Hi Haneef,

CurrentRecordContextChange do not get called when the grid model table gets updated. Can you tell me which event should I put the logic to refresh the summary. As I mentioned to you when I click on header for sort the refresh work for summaries. Can you tell me which event gets fired when I click on column header which set model table or summary to dirty.
