How to set style for ComboBox of the GridComboBoxColumn in WPF DataGrid(SfDataGrid)?

About the sample

This example illustrates how to set style for ComboBox of the GridComboBoxColumn in WPF DataGrid(SfDataGrid).

WPF DataGrid (SfDataGrid) doesn’t have direct support to set style for the ComboBox in the GridComboBoxColumn. However, you can achieve this by creating custom GridCellComboBoxRenderer.

<Window.Resources>
    <Style TargetType="ComboBox" x:Key="comboBoxStyle">
        <Setter Property="Foreground" Value="Blue"/>
    </Style>
</Window.Resources>

public MainWindow()
{
    InitializeComponent();

    this.dataGrid.CellRenderers["ComboBox"] = new CustomComboBoxCellRenderer();
}


public class CustomComboBoxCellRenderer : GridCellComboBoxRenderer
{
    public override void OnInitializeEditElement(DataColumnBase dataColumn, ComboBox uiElement, object dataContext)
    {
        base.OnInitializeEditElement(dataColumn, uiElement, dataContext);
        uiElement.Style = App.Current.MainWindow.Resources["comboBoxStyle"] as Style;
    }
}
