XamDataGrid ComboBoxField input to uppercase
posted

Hi,

I have a XamDataGrid with a ComboBoxField that is editable. I would like to force all characters to be upper case when the user is typing.

I managed it for TextField using a style with 'CharacterCasing'.

Here is my XamDataGrid XAML:

<igDP:XamDataGrid
	x:Name="myGrid"
	DataSource="{Binding Path=MyGridDataSource}"
	RecordLoadMode="LoadOnDemand"
	ScrollingMode="Immediate"
	ScrollViewer.CanContentScroll="True"
	VirtualizingPanel.IsVirtualizing="True"
	VirtualizingPanel.VirtualizationMode="Recycling"
	VirtualizingPanel.CacheLength="10"
	VirtualizingPanel.CacheLengthUnit="Item"
	GroupByAreaLocation="None"
	>
	<igDP:XamDataGrid.Resources>
		<Style TargetType="{x:Type TextBox}">
			<Setter Property="CharacterCasing" Value="Upper"/>
		</Style>
	</igDP:XamDataGrid.Resources>
	<igDP:XamDataGrid.FieldLayoutSettings>
		<igDP:FieldLayoutSettings
			HighlightAlternateRecords="True"
			FilterUIType="LabelIcons"
			ExpansionIndicatorDisplayMode="CheckOnDisplay"
			AllowClipboardOperations="Copy"
			AllowAddNew="True"
			AddNewRecordLocation="OnBottom"
			AutoGenerateFields="False"
			HeaderPlacement="OnRecordBreak"
			AutoFitMode="ExtendLastField"
			>
		</igDP:FieldLayoutSettings>
	</igDP:XamDataGrid.FieldLayoutSettings>
	<igDP:XamDataGrid.FieldSettings>
		<igDP:FieldSettings
			FilterLabelIconDropDownType="MultiSelectExcelStyle"
			AllowSorting="True"
			LabelClickAction="SortByMultipleFields"
			AllowEdit="True"
			ScrollViewer.CanContentScroll="True"
			VirtualizingPanel.IsVirtualizing="False"
			VirtualizingPanel.VirtualizationMode="Standard"
			VirtualizingPanel.CacheLength="10000"
			VirtualizingPanel.CacheLengthUnit="Item"
			/>
	</igDP:XamDataGrid.FieldSettings>
	<igDP:XamDataGrid.FieldLayouts>
		<igDP:FieldLayout>
			<igDP:FieldLayout.Fields>
				<igDP:ComboBoxField Name="MyComboBox" Label="MyComboBox" IsEditable="True">
					<igDP:ComboBoxField.EditorStyle>
						<Style TargetType="igWpf:XamComboEditor">
							<Setter Property="ItemsSource" Value="{Binding Path=DataContext.MyInitialValues, RelativeSource={RelativeSource AncestorType={x:Type igDP:XamDataGrid}}}"/>
						</Style>
					</igDP:ComboBoxField.EditorStyle>
				</igDP:ComboBoxField>
				<igDP:TextField Name="MyText" Label="MyText" VerticalContentAlignment="Stretch"/>
			</igDP:FieldLayout.Fields>
		</igDP:FieldLayout>
	</igDP:XamDataGrid.FieldLayouts>
</igDP:XamDataGrid>

How can I achive this for the ComboBoxField?

    I managed to find it myself.

    First add an event handler:

    <Style TargetType="igWpf:XamComboEditor">
    <Setter Property="ItemsSource"
            Value="{Binding Path=DataContext.ReferenceTypes, RelativeSource={RelativeSource AncestorType={x:Type igDP:XamDataGrid}}}" />
    <EventSetter Event="EditModeStarted" Handler="XamComboEditor_EditModeStarted"/>
</Style>

    In the handler use this:

    private void refType_EditModeStarted( object sender, Infragistics.Windows.Editors.Events.EditModeStartedEventArgs e )
{
    var xce = (XamComboEditor)sender;
    var textbox = XamlUtilities.FindChild<TextBox>(xce, "PART_EditableTextBox"); // name can also be NULL as the first TextBox shall be returned.
    if ( textbox == null )
        return;

    textbox.CharacterCasing = CharacterCasing.Upper;
}

// XamlUtilities is a custom class and source of "FindChild" is available at stackoverflow.com
