How to open the DropDown with a single click in the GridComboBoxColumn in WinRT DataGrid?
You can open the DropDown with a single click in the GridComboBoxColumn by deriving a new class from the GridCellComboBoxRenderer and overriding the OnEditElementLoaded virtual method as follows.
C#
public class ComboBoxRenderer : GridCellComboBoxRenderer
{
protected override void OnEditElementLoaded(object sender, System.Windows.RoutedEventArgs e)
{
base.OnEditElementLoaded(sender, e);
var combobox = sender as ComboBox;
combobox.IsDropDownOpen = true;
}
}
Refer to the following code example to remove the default GridCellComboBoxRenderer and add the customized GridCellComboBoxRendererExt to the SfDataGrid.CellRenderer collection and Set EditTrigger as OnTap in SfDataGrid.
C#
public MainWindow()
{
InitializeComponent();
//Default combobox cell renderer is removed.
this.sfgrid.CellRenderers.Remove("ComboBox");
//Customized combobox cell renderer is added.
this.sfgrid.CellRenderers.Add("ComboBox", new ComboBoxRenderer());
}
Xaml
<syncfusion:SfDataGrid Name="sfgrid"
AllowEditing="True"
AutoGenerateColumns="False"
ColumnSizer="SizeToHeader"
EditTrigger="OnTap"
ItemsSource="{Binding StoreLists}">
