How to set the default display text for GridComboBox column in UWP DataGrid?
In UWP DataGrid, GridComboBoxColumn does not have direct support to display default text on it when there is no selected Item. You can change default text using ComboBoxValueConverter and DisplayBinding property of the column.
<Page.Resources>
<local:ComboBoxValueConverter x:Key="comboBoxValueConverter"/>
</Page.Resources><syncfusion:SfDataGrid Name="dataGrid"
AutoGenerateColumns="False"
AllowEditing="True"
ColumnSizer="Auto"
ItemsSource="{Binding Employees}">
<syncfusion:SfDataGrid.Columns>
<syncfusion:GridTextColumn MappingName="FirstName" HeaderText="First Neme" ColumnFilter="DisplayText" />
<syncfusion:GridTextColumn MappingName="LastName" HeaderText="Last Name" />
<syncfusion:GridTextColumn MappingName="ID"/>
<syncfusion:GridTextColumn MappingName="Title" />
<syncfusion:GridTextColumn MappingName="Salary" />
<syncfusion:GridComboBoxColumn MappingName="ReportsTo" HeaderText="Reports To" ItemsSource="{Binding Reporters}" DisplayBinding="{Binding Path=ReportsTo, Converter={StaticResource comboBoxValueConverter}}"/>
</syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>
public class ComboBoxValueConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, string language)
{
if (string.IsNullOrEmpty(value.ToString()))
value = "Select a Value";
return value;
}
public object ConvertBack(object value, Type targetType, object parameter, string language)
{
throw new NotImplementedException();
}
}
