I am trying to mimick the DataTable.Select("Col1=1 and Col2='b'") method at the ggc level.

I want to select a group a records that meets a certain criteria without setting a filter on the ggc and then take some action on those records, for example, delete those records. How can I accomplish that?

I want to do something like...

RecordsInDetailsCollection recs = this.gridGroupingControl1.....

foreach(Record rec in recs)

Hi James,

Thanks for being patience.

This can be achieved by using the GridConditionalFormatDescriptor and deleting the records based on the condition. The following is the code snippet, please try it and let us know if you need any further assistance.
>>>>>>>>>>>>>>>>>>Code Snippet <<<<<<<<<<<<<<<<<<<<
GridConditionalFormatDescriptor desc = new GridConditionalFormatDescriptor();
desc.Expression = "[CustomerID] LIKE 'A*'";

foreach (Record rec in this.gridGroupingControl1.Table.Records)
if (desc.CompareRecord(rec))

Please refer to the following sample for more details

Kindly let us know if you need any further assistance.
Have a nice day.

Best regards,

DO I have to iterate thru all the records again to do a comparison before I delete. If I have a thousand records, that'll be too much.

I want to do something like...

DataRow[] rows = DataTable.Select("Name LIKE 'A*'");

foreach(DataRow row in rows)

Hi James,

Thank you for being patience.

Please try the following technique, a filter condition is applied to the grid and it will be reset after the records being deleted. Please refer to the following code snippet and let us know if you need any further assistance.

>>>>>>>>>>>>>>>>>>>>>>>>>>> this.gridGroupingControl1.TableDescriptor.RecordFilters.Add("[CustomerID] LIKE 'A*'");
FilteredRecordsInTableCollection reco = this.gridGroupingControl1.Table.FilteredRecords;
foreach (Record r in reco)

Have a nice day.

Best regards,

The only problem with this is that I have the grid visible, so the user will see the filter being applied in front of them and will be like... "where did the other records go?".

Is there are way that I apply the filter to get the records but not have the filter appied in the UI
