How to set row height of Xamarin DataGrid?

Environment

Product Version	R3 2021
Product	DataGrid for Xamarin

Description

It's a common requirement to define explicitly the height of the DataGrid rows as well as the height of the column headers. DataGrid does not expose direct API, still, there are means for setting the row heights through the TextMargin property of the CellContentStyle and HeaderStyle properties of the columns.

Solution

Let's have the following simple DataGrid definition:

<telerikDataGrid:RadDataGrid x:Name="DataGrid"/>

Add a simple ItemsSource:

this.DataGrid.ItemsSource = new List<Data>
 {
    new Data { Country = "India", Capital = "New Delhi"},
    new Data { Country = "South Africa", Capital = "Cape Town"},
    new Data { Country = "Nigeria", Capital = "Abuja" },
    new Data { Country = "Singapore", Capital = "Singapore" } 
 };

where Data object is defined like this:

public class Data
{
    public string Country { get; set; }
    public string Capital { get; set; }
}

To apply different height, define manually the needed columns and set their CellContentStyle property to a DataGridTextCellStyle with TextMargin and HeaderStyle property to a DataGridColumnHeaderStyle again with TextMargin:

<telerikDataGrid:RadDataGrid x:Name="DataGrid"
                             AutoGenerateColumns="False">
    <telerikDataGrid:RadDataGrid.Columns>
        <telerikDataGrid:DataGridTextColumn PropertyName="Country" HeaderText="Country">
            <telerikDataGrid:DataGridTextColumn.HeaderStyle>
                <telerikDataGrid:DataGridColumnHeaderStyle TextFontSize="18" 
                                                           TextMargin="20" />
            </telerikDataGrid:DataGridTextColumn.HeaderStyle>
            <telerikDataGrid:DataGridTextColumn.CellContentStyle>
                <telerikDataGrid:DataGridTextCellStyle FontSize="18" 
                                                       TextMargin="20" 
                                                       TextColor="DarkGreen" />

            </telerikDataGrid:DataGridTextColumn.CellContentStyle>
        </telerikDataGrid:DataGridTextColumn>
        <telerikDataGrid:DataGridTextColumn PropertyName="Capital" HeaderText="Capital">
            <telerikDataGrid:DataGridTextColumn.HeaderStyle>
                <telerikDataGrid:DataGridColumnHeaderStyle TextFontSize="18" 
                                                           TextMargin="20" />
            </telerikDataGrid:DataGridTextColumn.HeaderStyle>
            <telerikDataGrid:DataGridTextColumn.CellContentStyle>
                <telerikDataGrid:DataGridTextCellStyle FontSize="18" 
                                                       TextMargin="20" />

            </telerikDataGrid:DataGridTextColumn.CellContentStyle>
        </telerikDataGrid:DataGridTextColumn>
    </telerikDataGrid:RadDataGrid.Columns>
</telerikDataGrid:RadDataGrid>
