SelectedRecordsChanged and SelectedRecordsChanging events not firing

[Alomgir Miah]

Hi,

1) The SelectedRecordsChanged and SelectedRecordsChanging in GroupingGrid is not firing. What am I doing wrong. I am trying to implement a master detail grid.

I will appreciate any sample with this implementation.

2) Is it possible to show master detail records in a single grid using DataSet DataRelations or I have to use two grids.

Thanks,
Alomgir

Hi Alomgir,

Thanks for your interest in Syncfusion Products.

Please refer to the following sample in which the master-detail relation in single grid is shown. The relations among the nested childs have to be added manually to achieve this along with dataset relations. The SelectedRecordsChanged and SelectedRecordsChanging events get fired only when the following properties were set.

this.gridGroupingControl1.TableOptions.AllowSelection = Syncfusion.Windows.Forms.Grid.GridSelectionFlags.None;
this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.MultiExtended;

Here is the sample.

I want to have the same behavior bug allowing me to selected cells only. Not all the row.

Hi Otavio Lima, 

 

To perform cell selection, you need to set the `gridGroupingControl1.TableOptions.AllowSelection` as `GridSelectionFlags.Cell`.  

Code snippet :  

this.gridGroupingControl1.TableOptions.AllowSelection = Syncfusion.Windows.Forms.Grid.GridSelectionFlags.Cell; 

 

You can get notification for the cell selection by using the SelectionChanged and SelectionChanging event. Please refer the code snippet below. 

Code snippet :  

this.gridGroupingControl1.TableModel.SelectionChanging += OnTableModel_SelectionChanging; 

this.gridGroupingControl1.TableModel.SelectionChanged += OnTableModel_SelectionChanged; 

private void OnTableModel_SelectionChanging(object sender, Syncfusion.Windows.Forms.Grid.GridSelectionChangingEventArgs e) 

{ 

    Console.WriteLine("Changing"); 

} 

 

private void OnTableModel_SelectionChanged(object sender, Syncfusion.Windows.Forms.Grid.GridSelectionChangedEventArgs e) 

{ 

    Console.WriteLine("Changed"); 

}
