MultiColumn Sorting in GGC

Hi, is it possible to have multiple column sorting in GGC? I have tried to do something like: DataView dv = new DataView(someDataTable); dv.Sort = "LastName, FirstName"; GGC.DataSource = dv; However, the displayed data is still unsorted. Any idea?

Hi Kai, Yes, it is possible to have multiple column sorts in GridGroupingControl. Below is a code snippet. this.gridGroupingControl1.TableDescriptor.SortedColumns.AddRange(new SortColumnDescriptor[] { new SortColumnDescriptor(colName1, ListSortDirection.Ascending), new SortColumnDescriptor(colName2, ListSortDirection.Descending), new SortColumnDescriptor(colName3, ListSortDirection.Ascending) }); Regards, Calvin.

Great! Thanks! >Hi Kai, > >Yes, it is possible to have multiple column sorts in GridGroupingControl.

Now, how can we enable the Ctrl-left click in GGC for user to do multi-column sorting? >Great! Thanks! > >>Hi Kai, >> >>Yes, it is possible to have multiple column sorts in GridGroupingControl.

Hi Kai, By default the multi column sort by Ctrl+Left Button Mouse Click is enabled. To enable/disable the multi column sort the AllowMultiColumnSort property must be set to true/false. Below is a code. this.gridGroupingControl1.TableOptions.AllowMultiColumnSort = false; Regards, Calvin.

It seems that the AllowMultiColumnSort property does not exists in 3.3 GGC. I have an AllowSortColumns property instead. Are they the same? I have explicitly set the AllowSortColumns property to true but it seems that the Ctrl-left click on column header trick still doesn''t work. Any idea? I have a predefined sorted column header in my form''s constructor. GGC.TableDescriptor.SortedColumns.AddRange(new SortColumnDescriptor[] { new SortColumnDescriptor(Col1), new SortColumnDescriptor(Col2) ... } }; and GGC.TableOptions.AllowSortColumns = true; >Hi Kai, > >By default the multi column sort by Ctrl+Left Button Mouse Click is enabled.

Hi Kai, The latest version (4.1.0.62) can be downloaded from the following link. ftp://syncpatch.syncfusion.com/EssentialStudio/v4.1.0.62/syncfusionessentialstudiosetup.exe In the 3.3 version the intent behavior can be achieved by handling the TableControlCellClick event. Below is code snippet. private void gridGroupingControl1_TableControlCellClick(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellClickEventArgs e) { // Check for CTRL - Key to do multi-column sorting..... if(((Control.ModifierKeys & Keys.Control) != 0)) { // Cancel the default sorting... e.Inner.Cancel = true; GridColumnDescriptor column = e.TableControl.Table.GetColumnDescriptorAt(e.Inner.RowIndex, e.Inner.ColIndex); string col = column.Name; if(this.gridGroupingControl1.TableDescriptor.SortedColumns.Contains(col)) { if(this.gridGroupingControl1.TableDescriptor.SortedColumns[col].SortDirection == ListSortDirection.Ascending) { this.gridGroupingControl1.TableDescriptor.SortedColumns[col].SortDirection = ListSortDirection.Descending; } else { this.gridGroupingControl1.TableDescriptor.SortedColumns[col].SortDirection = ListSortDirection.Ascending; } } else { this.gridGroupingControl1.TableDescriptor.SortedColumns.Add(col, ListSortDirection.Ascending); } } } Regards, Calvin.

Works great! Can we upgrade from 3.3 to 4.1.0.62 for free? >Hi Kai, > >The latest version (4.1.0.62) can be downloaded from the following link. >ftp://syncpatch.syncfusion.com/EssentialStudio/v4.1.0.62/syncfusionessentialstudiosetup.exe >In the 3.3 version the intent behavior can be achieved by handling the TableControlCellClick event.

Hi Kai, Thanks for the update. You can open a Direct-Trac to get details for upgrading, and it cost to upgrade from 3.X to 4.1. Regards, Calvin.
