How to achieve the EditorSelectionBehavior as SelectAll in GridTemplateColumn in WinUI DataGrid (SfDataGrid)?
The EditorSelectionBehavior as SelectAll will not work when the GridTemplateColumn is in edit mode in WinUI DataGrid (SfDataGrid). Because the element loaded inside the edit template cannot be predicted. You can achieve this by programmatically selecting all the text whenever the edit element got focused.
In the following sample, TextBox has been loaded as an edit element of GridTemplateColumn and all the text has been selected which is present inside the TextBox by setting the TextBox custom property AutoSelectable to true.
Refer to the following code snippet to achieve the EditorSelectionBehavior as SelectAll in GridTemplateColumn.
XAML
<Syncfusion:SfDataGrid x:Name="dataGrid"
ItemsSource="{Binding Orders,Mode=TwoWay}"
AllowFiltering="True"
EditorSelectionBehavior="SelectAll"
ShowGroupDropArea="True"
AutoGenerateColumns="False"
AllowEditing="True">
<Syncfusion:SfDataGrid.Columns>
<Syncfusion:GridNumericColumn MappingName="OrderID" HeaderText="Order ID" />
<Syncfusion:GridTemplateColumn MappingName="CustomerID">
<Syncfusion:GridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding CustomerID}" />
</DataTemplate>
</Syncfusion:GridTemplateColumn.CellTemplate>
<Syncfusion:GridTemplateColumn.EditTemplate>
<DataTemplate>
<local:CustomTextBox AutoSelectable="True" Text="{Binding CustomerID, Mode=TwoWay}" />
</DataTemplate>
</Syncfusion:GridTemplateColumn.EditTemplate>
</Syncfusion:GridTemplateColumn>
<Syncfusion:GridTextColumn MappingName="ShipCity" HeaderText="Ship City" />
<Syncfusion:GridNumericColumn MappingName="UnitPrice" HeaderText="Unit Price" />
<Syncfusion:GridCheckBoxColumn MappingName="Review" HeaderText="Review" />
</Syncfusion:SfDataGrid.Columns>
</Syncfusion:SfDataGrid>
Code snippet related to CustomTextBox
public class CustomTextBox : TextBox
{
public CustomTextBox() : base()
{
}
public static bool GetAutoSelectable(DependencyObject obj)
{
return (bool)obj.GetValue(AutoSelectableProperty);
}
public static void SetAutoSelectable(DependencyObject obj, bool value)
{
obj.SetValue(AutoSelectableProperty, value);
}
public static readonly DependencyProperty AutoSelectableProperty =
DependencyProperty.RegisterAttached("AutoSelectable", typeof(bool), typeof(CustomTextBox), new PropertyMetadata(false, AutoFocusableChangedHandler));
private static void AutoFocusableChangedHandler(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
if (e.NewValue != e.OldValue)
{
if ((bool)e.NewValue == true)
{
(d as TextBox).GotFocus += OnGotFocusHandler;
}
else
{
(d as TextBox).GotFocus -= OnGotFocusHandler;
}
}
}
private static void OnGotFocusHandler(object sender, RoutedEventArgs e)
{
(sender as TextBox).SelectAll();
}
}
