GroupCaptionSection

To get the records of a particular GroupCaptionSection, you can handle the TableControlCellMouseDown event and loop through the records in that group. To run the sample, right-click any GroupCaptionCell of a group to retrieve the records that belong to that group.

C#

//Hooks the TableControlCellMouseDown event in Form_Load
this.gridGroupingControl1.TableControlCellMouseDown += gridGroupingControl1_TableControlCellMouseDown;
void gridGroupingControl1_TableControlCellMouseDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellMouseEventArgs e)
{
   if(e.Inner.MouseEventArgs.Button == MouseButtons.Right)
   {
      //Gets the style for the clicked cell
      GridTableCellStyleInfo style = e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex);
      Element el = style.TableCellIdentity.DisplayElement;
      GridCaptionRow gridCaptionRow = style.TableCellIdentity.DisplayElement as GridCaptionRow;
      if(gridCaptionRow != null)
      {
         string s = "";
         foreach (Record rec in gridCaptionRow.GetCaptionSection().ParentGroup.Records)
         {
            //Retrieves the Values from the Record 
            s += rec.GetValue("Name").ToString() + " " + rec.GetValue("WorkingBranch").ToString() + " " + Environment.NewLine;
         }
         //Shows the Content in the MessageBox
         MessageBox.Show(s);
      }
   }
}

VB

'Hooks the TableControlCellMouseDown event in Form_Load
Me.gridGroupingControl1.TableControlCellMouseDown += gridGroupingControl1_TableControlCellMouseDown
Private Sub gridGroupingControl1_TableControlCellMouseDown(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellMouseEventArgs)
   If e.Inner.MouseEventArgs.Button = MouseButtons.Right Then
      'Gets the style for the clicked cell
      Dim style As GridTableCellStyleInfo = e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex)
      Dim el As Element = style.TableCellIdentity.DisplayElement
      Dim gridCaptionRow As GridCaptionRow = TryCast(style.TableCellIdentity.DisplayElement, GridCaptionRow)
      If gridCaptionRow IsNot Nothing Then
         Dim s As String = ""
         For Each rec As Record In gridCaptionRow.GetCaptionSection().ParentGroup.Records
   'Retrieves the Values from the Record 
   s &= rec.GetValue("Name").ToString() & " " & rec.GetValue("WorkingBranch").ToString() & " " & Environment.NewLine
         Next rec
         'Shows the Content in the MessageBox
         MessageBox.Show(s)
      End If
   End If
End Sub
