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.
