Count/get selected rows in detail view

Hello,

How to get number of selected rows and and value from specific columns from selected rows when I have multiple selected rows in child grid but outside ChildGrid_SelectionChanged(), for example on Button click.

So far I have this:

SfDataGrid childGrid = new SfDataGrid();

 public From1()
        {
            InitializeComponent();
            childGrid.SelectionChanged += ChildGrid_SelectionChanged;
           
            InitGrid();
        }

 private void ChildGrid_SelectionChanged(object sender, Syncfusion.WinForms.DataGrid.Events.SelectionChangedEventArgs e)
        {
          
         
        }

 private void InitGrid()
        {              

            GridViewDefinition orderDetailsView = new GridViewDefinition();
            orderDetailsView.RelationalColumn = "IzdatnicaStavke";        
            childGrid.QueryRowStyle += ChildGrid_QueryRowStyle;         
            childGrid.Style.HeaderStyle.BackColor = Color.Yellow;
            childGrid.AutoGenerateColumns = false;
            childGrid.RowHeight = 21;
            childGrid.SelectionMode = GridSelectionMode.Extended;
            childGrid.SelectionUnit = SelectionUnit.Row;
            NumberFormatInfo nfi = new NumberFormatInfo();
            nfi.NumberDecimalDigits = 2;
            nfi.NumberGroupSizes = new int[] { };
            childGrid.Columns.Add(new GridTextColumn() { MappingName = "IDIzdatnica", HeaderText = "ID", Visible = false });
            childGrid.Columns.Add(new GridTextColumn() { MappingName = "SifraRD", HeaderText = "Šifra rd." });
            childGrid.Columns.Add(new GridTextColumn() { MappingName = "OpisArtikla", HeaderText = "Opis/naziv" });
            childGrid.Columns.Add(new GridTextColumn() { MappingName = "NazivGrupe", HeaderText = "Grupa" });
            childGrid.Columns.Add(new GridTextColumn() { MappingName = "JedMjera", HeaderText = "Jed. mj." });                     
            childGrid.Columns.Add(new GridNumericColumn() { MappingName = "Kolicina", HeaderText = "Količina", NumberFormatInfo = nfi });           
            childGrid.Columns.Add(new GridTextColumn() { MappingName = "Napomena", HeaderText = "Napomena" });
         
            orderDetailsView.DataGrid = childGrid;
            this.gridIzdatnica.DetailsViewDefinitions.Add(orderDetailsView);
            this.gridIzdatnica.HideEmptyGridViewDefinition = true;

        }

Problem is that whatever I do the number of selected items are always 0 in childGrid.

Hi Josip,  
    
Thank you for using Syncfusion controls.   
   
You can achieve your requirement “to get the selected items count for DetailsViewDataGrid” by using SfDataGrid.SelectedDetailsViewGrid.SelectedItems property.    
   
Please find the below code snippet.  
   
var count = this.sfDataGrid1.SelectedDetailsViewGrid.SelectedItems.Count;   
   
Please find the below sample link.  
    
   
Please let us know, if you require further assistance on this.   
    
Regards,   
Gowtham.
