How to apply multiple selection colors in Xamarin.Forms DataGrid?

1 min read

By default, Xamarin.Forms DataGrid applies a common background color for the selected rows. However, it also provides extensibility to have multiple selection colors when touching the rows by writing a custom SelectionController derived from GridSelectionController property. You need to override the GetSelectionColor method to apply different colors for selection in runtime.

The following code example illustrates how to set different colors for the selected rows in SfDataGrid.

<ContentPage.BindingContext>
    <local:ViewModel x:Name="viewModel"/>
  </ContentPage.BindingContext>
 
<ContentPage.Content>
  <syncfusion:SfDataGrid x:Name="datagrid"
                         ColumnSizer="Star"
                         AutoGenerateColumns="True"
                         SelectionMode="Multiple"
                         ItemsSource="{Binding OrdersInfo}"> 
  </syncfusion:SfDataGrid>
</ContentPage.Content>

public class CustomSelectionController : GridSelectionController
{
public Color[] SelectionColors { get; set; }
public CustomSelectionController(SfDataGrid datagrid)
{
    this.DataGrid = datagrid;
    SelectionColors = new Color[8]
    {
        Color.Aqua,
        Color.Black,
        Color.Teal,
        Color.Gray,
        Color.Green,
        Color.Maroon,
        Color.Navy,
        Color.Purple
    };
} 
public override Color GetSelectionColor(int rowIntex, object rowData)
{
    if (SelectionColors != null)
        return SelectionColors[rowIntex % 8];
    else
        return Color.Blue;
}
