wpf listview bind with list of string type

As we all know the wpf listview is inherited class of listbox and have almost all the properties of listbox. We have learnt listbox binding with string list in our earlier post. In this article we bind the listview with the same string list.

Just place a wpf listview having only name property, because we have to access that wpf listview in our code behind file. We can also use height and width property of the listview, if the data items are of lengthy string.
<ListView>
<ListView.Name>listView</ListView.Name>
</ListView>

Now use the same list of string as in previous post i.e.
List<string> strList = new List<string>();
strList.Add("London");
strList.Add("Italy");
strList.Add("California");
strList.Add("France");
listView.ItemsSource = strList;

Now look out the last statement, it will set the item source of the wpf listview as this string list. When we run the project it will show a listview with four items:

To get selected item the same procedure will follow as in listview bind with grid resource.

The CheckBoxList control displays the list of data as a CheckBox from which you can make a multiple selection. The CheckBoxList control exists within the System.Web.UI.WebControls namespace. You can select multiple items in this control because In this control you have some options. The CheckBoxList control has no non-inherited methods or events.

{
    protected void Page_Load(object sender, EventArgs e)
    {
        DataSet ds = new DataSet();
      
        ds.ReadXml(Server.MapPath("countries.xml"));

WPF Slider Example: ValueChanged event, minimum and maximum

Slider : It means slide the button from left to right or vise versa. When we slide it then we can do some changes in other things like change background color etc. WPF slider control have two public properties, first one is minimum and second one is maximum. Slider works from minimum to maximum also depends on user condition.


Example :  Drag and drop a slider control on WPF design window with two attributes, which are:
  • Minimum: get or set the minimum value of the control. By default it is zero.
  • Maximum: get or set the maximum value of the control. By default it is Ten.
Now after drag the control, your xaml code look like:

<Slider Name="slider" Minimum="0" Maximum="100" Value="25" Height="25" Width="300">
</Slider>

Run the code and the slider control is on your screen, with value 25- defined above.

Slider control WPF

Ticks can be used to place the slider on exact position. We can enable ticks by using the property TickPlacement. It have four values i.e. None, Both, TopLeft and BottomRight.
  • None: it will give a simple look as in above image. 
  • TopLeft: the ticks will placed on left with vertical orientation and top with horizontal. 
  • BottomRight: the ticks will placed on right with vertical orientation and bottom with horizontal.
  • Both: It is used on both left and right, when the orientation is vertical.
The following image shows the slider control with TickPlacement set to TopLeft.
