How to Get Row Position in Windows Forms GridGroupingControl

18 Nov 20181 minute to read

From the row index, you can get the element displayed at that row. If it is a record row, then the element’s parent record’s unsorted position will give the underlying DataRow position.

C#

Table table = e.TableControl.Table;

//Gets the current display element.
Element el = table.DisplayElements[e.rowIndex];

//Gets the current record.
Record r = el.ParentRecord;

//Finds its row position.
int dataRowPos = table.UnsortedRecords.IndexOf(r);

//Retrieves the corresponding data row from the datasource.
CustomersDataRow row = dataSource.Rows[dataRowPos];

// Accesses the CustomerId value of the current record.
string id = row.CustomerId;

VB.NET

Dim table As Table = e.TableControl.Table 

'Gets the current display element.
Dim el As Element = table.DisplayElements(e.rowIndex)

'Gets the current record. 
Dim r As Record = el.ParentRecord 

'Finds its row position.
Dim dataRowPos As Integer = table.UnsortedRecords.IndexOf(r)

'Retrieves the corresponding data row from the datasource. 
Dim row As CustomersDataRow = dataSource.Rows(dataRowPos)

'Accesses the CustomerId value of the current record. 
Dim id As String = row.CustomerId
