[Manolo Capdevila]

Hi,

I need to select some rows, but when I've a lot of data, I need search the rows to select.

The problem is, when I select a row, if I search for a new row, I lose the previously selected row.

I attach an example.

Thanks

Hi Manolo, 

Thanks for contacting Syncfusion support. 

To maintain the selection of the records even after searching for the values we suggest you to define the field value for the checkbox column. Please refer the below code example. 

@(Html.EJ().Grid<object>("FlatGrid") 

         .Datasource((IEnumerable<object>)ViewBag.datasource)         

        .AllowScrolling() 

         .AllowSorting()    /*Sorting Enabled*/ 

         .AllowPaging()    /*Paging Enabled*/ 

         .AllowSearching() 

            .SelectionType(SelectionType.Multiple) 

             

              .ToolbarSettings(toolbar => 

                { 

                 toolbar.ShowToolbar().ToolbarItems(items => 

                 { 

                     items.AddTool(ToolBarItems.Search); 

                }); 

              }) 

         .Locale("es-ES") 

        .Columns(col => 

        { 

            col.Type("checkbox").Field("Select").Width(50).Add(); 

            col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Width(75).Add(); 

            col.Field("CustomerID").HeaderText("Customer ID").Width(80).Add();
