Examples
Here is how to declare a Slider in UIXML:
<Slider Name="slider" Minimum="50" Maximum="250" Value="125" Margin="8" ValueChanged="Slider_ValueChanged" />
And the corresponding event handler in the code-behind:
private void Slider_ValueChanged(object sender, EventArgs e)
{
string text = slider.Value.ToString();
MessageBox.Show(text, string.Empty);
}
Also, a Slider can be created from code:
var Slider = new Alternet.UI.Slider() { Minimum = 50, Maximum = 200, Value = 125, Margin = new Thickness(0, 0, 0, 5) };
Remarks
The Slider is a scrollable control similar to the scroll bar control. You can configure ranges through which the value of the Value property of a slider scrolls by setting the Minimum property to specify the lower end of the range and the Maximum property to specify the upper end of the range.
The slider can be displayed horizontally or vertically.
You can use this control to input numeric data obtained through the Value property. You can display this numeric data in a control or use it in code.
Examples of how a Slider can look on different platforms:
Set Value property to represent the current position of the scroll box on the slider.
A Slider, like any other Control, can be disabled by setting its Enabled property to false.
