ComboBox DisplaymemberPath Binding

[Manas]

Hello there,
I need to convert the Transactiondate (of type DateTime) to show in 24 hour format in a Combobox
with IsEditable=True and upon selection of an item the ComboBox needs to show the selected date in 24hr format.
This version converts the dates to 24hr format but up on Item selection it shows the class name
instead of the selected date in 24 hr format): What am I doing wrong or missing?
<telerikInput:RadComboBox x:Name="ccTransactionDate" IsEditable="True" Grid.Row="2" Grid.Column="1">
<telerikInput:RadComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=TransactionDate, StringFormat='MM/dd/yyyy HH:mm:ss'}" />
</DataTemplate>
</telerikInput:RadComboBox.ItemTemplate>
</telerikInput:RadComboBox>






However when IsEditable is False it Works fine (but don't want to use this because want editable ComboBox):



<telerikInput:RadComboBox x:Name="ccTransactionDate" IsEditable="False" Grid.Row="2" Grid.Column="1">
<telerikInput:RadComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=TransactionDate, StringFormat='MM/dd/yyyy HH:mm:ss'}" />
</DataTemplate>
</telerikInput:RadComboBox.ItemTemplate>
</telerikInput:RadComboBox>





Thanks,
Manas

Hi Manas,

I would suggest you to use the attached property TextSearch.TextPath in Telerik.Windows.Controls.dll assembly:  

<telerikInput:RadComboBox x:Name="ccTransactionDate" IsEditable="True" Grid.Row="2" Grid.Column="1" telerik:TextSearch.TextPath="TransactionDate">
<telerikInput:RadComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=TransactionDate, StringFormat='MM/dd/yyyy HH:mm:ss'}" />
</DataTemplate>
</telerikInput:RadComboBox.ItemTemplate>
</telerikInput:RadComboBox>

Please, pay attention to that the selected item displayed in the TextBlock cannot be formatted. In this case you could use for the binding a property that returns already formatted DateTime string.

I hope this helps.

Sincerely yours,
George
