How to change the row height event in .NET MAUI DataGrid?

The .NET MAUI DataGrid provides support for setting row height based on the row content using the QueryRowHeight event.

To trigger this event at runtime, like resizing the windows or resizing the column, we can use the InvalidateRowHeight method to invoke the event at runtime.

XAML

<syncfusion:SfDataGrid x:Name="dataGrid"
                        AutoGenerateColumnsMode="None"                       
                        AllowResizingColumns="True"
                        ColumnResizing="dataGrid_ColumnResizing"
                        GridLinesVisibility="Both"
                        HeaderGridLinesVisibility="Both"
                        x:DataType="viewModel:EmployeeViewModel" 
                        QueryRowHeight="dataGrid_QueryRowHeight"
                        PropertyChanged="dataGrid_PropertyChanged"
                        ItemsSource="{Binding EmployeeInformation}">
    <syncfusion:SfDataGrid.Columns>
        <syncfusion:DataGridTextColumn HeaderText="Name" MappingName="Name"  />
        <syncfusion:DataGridTextColumn HeaderText="Employee ID" MappingName="EmployeeID"  />
        <syncfusion:DataGridTextColumn HeaderText="Telephone" MappingName="Telephone"/>
        <syncfusion:DataGridTextColumn HeaderText="About" MappingName="About"/>
    </syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>

C#

This event will set the row height based on its content.

private void ordersDataGrid_QueryRowHeight(object sender, Syncfusion.Maui.DataGrid.DataGridQueryRowHeightEventArgs e)
{
    if (e.RowIndex > 0)
    {
        e.Height = e.GetIntrinsicRowHeight(e.RowIndex);
        e.Handled = true;
    }
}

This event will be called when the column is resized. We will get the visible rows in the view, and then we will set the row height dynamically when the column is resized.

private void dataGrid_ColumnResizing(object sender, Syncfusion.Maui.DataGrid.DataGridColumnResizingEventArgs e)
{
    var VisibleRowCount = dataGrid.GetVisualContainer().ScrollRows.GetVisibleLines().Count;
    for (int i = 0; i < VisibleRowCount; i++)
    {
        dataGrid.InvalidateRowHeight(i);
    }
}

This event will be called when the window or the datagrid is resized. We will get the visible rows in the view, and then we will set the row height dynamically.

private void ordersDataGrid_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
{
    if (e.PropertyName!.Equals("Width"))
    {
        var VisibleRowCount = dataGrid.GetVisualContainer().ScrollRows.GetVisibleLines().Count;
        for (int i = 0; i < VisibleRowCount; i++)
        {
            dataGrid.InvalidateRowHeight(i);
        }
    }
}
