UWP: Navigation using SplitView

SplitView has two panes and in one of them you place items that allow you to navigate to the details of that item and its contents. You can basically use some event handlers to the items and when the event occurs, you display the content for the item.

Here is the scheme for navigation:


SplViewNav_0

You have three objects in the SplitView pane (Rose, Jasmine, Lily). You attach events to these objects and when the event is fired, you display the related content in the area on the right, the Content.

Before you read this post, please make sure you read the two following posts:

Navigation with SplitView:

Description of App in xaml designer

Start with a UWP Blank project and provide a name. In this it was named JSplitView.
The code for MainPage.xaml is shown here:


SplViewNav_1

I just palced a ListBox control and inside of which I placed three ListBoxItems named itm1, itm2 and itm3.

I also arranged for the event by invoking the KeyDown event. Although I used KeyDown of ListBox, you could have used three Button's and use its Click event.

The Content pane is the Grid element where in I placed a placefolder for an image with the name Img.

In the Design, the app appears as shown in the first image above in the post.

As soon as you place the 'KeyDown' event in the MainPage.xaml, the events show up in the MainPage.xaml.cs page as shown:


SplViewNav_2

Now if you have read my earlier posts, you would see that I wrote code in the Itm_KeyDown events to access the three image files in the Assets folder. Of course, you need to make sure that you add the three images (the images may be your own) to the Assets folder.

This completes the app and all you need to do is to Build, Deploy and Run.
When the app is launched, this is what you see:

This image is when any key is pressed when the cursor is on the item when run on Local Machine.

UWP: Displaying formatted text in a TextBox Control

Image
The entry you make in a text box control is of data type text and sometimes you need to format it as a currency with thousands separator while displaying. Also, if the number of decimal places you enter is more than 2, you need to round it up to 2 in the output. How do you code this in a UWP app? Create a UWP page starting from a Blank UWP project with three controls as shown. There are two text boxes and a button. You enter a number in the top textbox (txt1) and click the button, the formatted currency will be displayed in the bottom textbox(txt2). The app displays as shown. Now provide for a click event for the button and insert code as shown: Convert_1 The string entered in txt1 is converted to data-type double, it is then 'rounded'. The rounded number is then formatted to show the currency symbol and the 1000's place delimiter you find, for example in Excel formatting. Here is the app after entering a number and c

UWP: XAML's ComboBox Control -Part 1

Image
Microsoft's Universal Windows Framework apps are well supported by Microsoft and you could use it for not only Windows but for other devices as well. You can also use UWP for cross-platform use. In the Universal Windows Platform (UWP) projects there is an advantage of one code that works on different device families (phone, tablet, desktop etc.). However, the UWP projects depend on using XAML.  ComboBox details can be seen in the Object Explorer of Visual Studio 2017 Community used in writing this post. In this post, I will show you how you may work with this controls for a UWP project.
