Default text of combobox

Question

i want a default text on my combobox as i have binded my combo box to certain list of items...here is my code of xaml file.

<ComboBox x:Name="ProjectComboBox" Text="{Binding ProjectNameBinding}" ItemsSource="{Binding projectList, ElementName=MainWin}" SelectedValuePath="_id" DisplayMemberPath="_name" SelectedItem="{Binding ProjectNameBindingClass, Mode=OneWayToSource}" Width="130" Background="White" BorderThickness="1" FontFamily="/TimeSheet;component/Resources/#Open Sans" FontSize="12" Canvas.Right="159" Canvas.Top="8" Height="47"> <ComboBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding _name}" TextWrapping="Wrap"/> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox>

it helps, if you ask a concrete question on the end of the text. it also if you describe what you already tried to achieve that - so you show own efforts instead of blindly letting others work for you. ;-) — L-Ray

Have you tried Text Property

<ComboBox x:Name="ProjectComboBox" IsEditable=True Text="{Binding ProjectNameBinding}" ....../>

or

You can use SelectedIndex Property and set it to 0(SelectedIndex=0) which displays first item in Source given.

or

you can do like this as in the link How to display default text "--Select Team --" in combo box on pageload in WPF?

I achieved it atlast by taking a new textblock and applying a trigger on it,and using the IsNullConverter class it helped

<TextBlock Text="Select Project" IsHitTestVisible="False" FontFamily="/TimeSheet;component/Resources/#Open Sans" FontSize="14" Canvas.Right="191" Canvas.Top="22"> <TextBlock.Resources> <Converters:IsNullConverter x:Key="isNullConverter"/> </TextBlock.Resources> <TextBlock.Style> <Style TargetType="TextBlock"> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=ProjectComboBox,Path=SelectedItem,Converter={StaticResource isNullConverter}}" Value="False"> <Setter Property="Visibility" Value="Hidden"/> </DataTrigger> </Style.Triggers> </Style> </TextBlock.Style> </TextBlock>
