SelectedAll reacords data grid

Radzen Studio Blazor WebAssembly
1

Hi ,
I am trying to add the functionality for multiselected rows in data grid. I can select one by one and delete at the end , but the checkbox at the header does not select all the rows at once . I have followed up the Multiselected component in documentation but still does not work . Can someone help me out ?

Multiple selection is demonstrated on this demo:
https://blazor.radzen.com/datagrid-multiple-selection

Check the header CheckBox Change code.

This is the code and still does not work :

<HeaderTemplate>
                <RadzenCheckBox  Name="Checkbox1" Change="@(args => selectedItem= args ? getProcessLocationsResult.ToList() : null)" TValue="bool" Value="@((getProcessLocationsResult!=null)? getProcessLocationsResult.Any(i => selectedItem!= null && selectedItem.Contains(i)):false)">
                </RadzenCheckBox>
              </HeaderTemplate>
