For result-filtered combobox functionality, I highly recommend you to look into the UXSearchBox control. You can bind the QueryText to the property in your ViewModel, perform the searching in server-side, and finally returns the data to be populated in the list.

For more information and walkthroughs on UXSearchBox, see UXSearchBox Overview.

Hi Andrzej,

As you pointed out, yes, it's possible to pass a parameter from dock button to the Window via the StartupParameters. The StartupParameters is defined in the WindowOptions instance that you pass along with the ApplicationURI.

Here's the code excerpt of the example that I took from our UXDesktopDock sample.

                <Intersoft:UXStackItem Text="Interestingness" Command="Intersoft:WindowCommands.LaunchApplication" CommandTarget="{Binding ElementName=SampleDesktop}">
                    <Intersoft:UXStackItem.CommandParameter>
                        <Intersoft:WindowOptions StartupParameters="Interestingness" ForceSingleInstance="True" ReactivateExistingInstance="True" Uri="/Intersoft.ClientUI.Samples.WindowControls;Intersoft.ClientUI.Samples.WindowControls.Views.UXDesktopDock.Photos"/>
                    </Intersoft:UXStackItem.CommandParameter>
                </Intersoft:UXStackItem>

Of course, in your case, you can define the CommandParameter for your specific object such as UXDesktopDockButton, instead of UXStackItem.

If you need to pass a dynamic parameter, feel free to bind the StartupParameters to the object that contains the value you want to transfer. I.e., StartupParameters="{Binding ViewModel.DynamicValue}"

When you pass the WindowOptions that contains StartupParameters to the target application, and assuming the target is an IWindow, you can obtain the value of the parameters in the window.StartupParameters in the Load event of the window. With this technique, you can elegantly pass the parameters without intermediate/proxy code.

For an example, the following code obtains the parameter sent from the UXStackItem in the previous code example.

private void Photos_Loaded(object sender, RoutedEventArgs e)
        {
            FlickrPhotosViewModel model = new FlickrPhotosViewModel();
            this.DataContext = model;

            if (this.StartupParameters == null)
                model.GetPhotosCommand.Execute("Interestingness");
            else
                model.GetPhotosCommand.Execute(this.StartupParameters.ToString());
        }

Let me know if it works in your end, or if you have other questions.

Hope this helps,

Hi Andrzej,

The new hotfix is now available (build 4), which includes the fix to this issue.

In your code, use this.NavigationContextExtended.QueryString in order to access the parameter.

Hello,

This issue has been fixed, the hotfix will be released early next week.

Thanks,

Hi Chris,

You've got it right, thanks for sharing your solution. That is the technique to create custom item type in an items control.

In another common scenario related to style customization, you may want to use ItemContainerStyleSelector of the control when you need to customize the style of the same target item type based on specific conditions. This allows you to perform the style conditioning in a separate class without have to override the control's class. More information and example about ItemContainerStyleSelector can be found here.

Hope this helps,
Jimmy
