How to Show Popup on Selecting the Same Record in .NET MAUI DataGrid?

This article demonstrates how to display a pop-up when a user selects the same record again in the .NET MAUI DataGrid. Using the SfPopup control, we can present detailed information about the selected employee in a pop-up window.

Xaml

<ContentPage.BindingContext>
    <local:EmployeeViewModel x:Name="viewModel" />
</ContentPage.BindingContext>

<Grid>
    <syncfusion:SfDataGrid x:Name="sfGrid"
                           GridLinesVisibility="Both"
                           HeaderGridLinesVisibility="Both"
                           ColumnWidthMode="Auto"
                           SelectionMode="Single"
                           NavigationMode="Cell"
                           AutoGenerateColumnsMode="None"
                           CellTapped="sfGrid_CellTapped"
                           ItemsSource="{Binding Employees}">

        <syncfusion:SfDataGrid.Columns>
            <syncfusion:DataGridNumericColumn MappingName="EmployeeID"
                                              Format="#"
                                              HeaderText="Employee ID" />
            <syncfusion:DataGridTextColumn MappingName="Name"
                                           HeaderText="Employee Name" />
            <syncfusion:DataGridTextColumn MappingName="Title"
                                           HeaderText="Designation" />
            <syncfusion:DataGridDateColumn MappingName="HireDate"
                                           HeaderText="Hire Date" />

        </syncfusion:SfDataGrid.Columns>

    </syncfusion:SfDataGrid>

    <!-- Syncfusion SfPopup -->
    <sfPopup:SfPopup x:Name="popup"
                     WidthRequest="400"
                     HeightRequest="250"
                     ShowFooter="True"
                     ShowHeader="True"
                     StaysOpen="False"
                     IsOpen="{Binding IsPopupOpen, Mode=TwoWay}"
                     >

        <sfPopup:SfPopup.HeaderTemplate>
            <DataTemplate>
                <Label Text="Employee Details" HorizontalOptions="Center"
                       FontSize="18"
                       FontAttributes="Bold" />
            </DataTemplate>
        </sfPopup:SfPopup.HeaderTemplate>

        <sfPopup:SfPopup.ContentTemplate>
            <DataTemplate>
                <VerticalStackLayout Padding="10">
                    <Label 
                           Text="{Binding SelectedEmployeeDetails}"
                           FontSize="16"
                           TextColor="Black" />
                </VerticalStackLayout>
            </DataTemplate>
        </sfPopup:SfPopup.ContentTemplate>

        <sfPopup:SfPopup.FooterTemplate>
            <DataTemplate>
                <Button Text="Close" WidthRequest="100" HeightRequest="40" 
                        Clicked="ClosePopup" />
            </DataTemplate>
        </sfPopup:SfPopup.FooterTemplate>

    </sfPopup:SfPopup>
</Grid>

Xaml.cs
The code below demonstrates how to show the popup when selecting the same record again in SfDataGrid.

private void ClosePopup(object sender, EventArgs e)
{
    popup.IsOpen = false;
}

private void sfGrid_CellTapped(object sender, Syncfusion.Maui.DataGrid.DataGridCellTappedEventArgs e)
{
    var employee = e.RowData as Employee;
    if (employee != null &&  sfGrid.SelectedRows.Contains(employee))
    { 
        viewModel.UpdateSelectedEmployee(employee);
    }
}

// EmployeeViewModel.cs
public void UpdateSelectedEmployee(Employee employee)
{
    if (employee != null)
    {
        SelectedEmployeeDetails = $"ID: {employee.EmployeeID}\nName: {employee.Name}\nPosition: {employee.Title}";
        IsPopupOpen = true;
    }
}
