How can I restrict selection of a Slider to the SelectedRange

Question

I would like to restrict a slider to the Selected Range. Ex:

Slider with minimum=0 and maximum=10

SelectionStart=3
SelectionEnd=7

I would like to restrict the slider thumb to only between 3 and 7.

I want the thumb to only be able to select 3 and 7 and any values in between.
Thumb should not be able to move left or right of the range.
Min and Max must stay as 0 and 10.
The Selected Range is dynamic, could change to 5 to 10 or 0 to 6 for example.

thanks in advance.

Not 100% clear. What you are trying to use it for and how? Do you want the slider to stop at 3 or 7 if moved to far left or right? Why not changing ins Maximum and Minimum (asking just in case)?

Hello,

Add an event handler for ValueChanged in the xaml:

C#

<slider x:name="slider" valuechanged="Slider_ValueChanged" />

Check the slider value in the code behind:

C#

private void Slider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
    if (e.NewValue < 3 | e.NewValue > 7)
        slider.Value = e.OldValue;
}

Valery.

can the 3 an 7 in your solution be dynamic, the Selected Range is variable.

Valery Possoz 9-Jan-15 16:16pm

yes use a variable for 3 and for 7.

int _min = selectedRange.Min;
int _max = selectedRange.Max;

and use them in the method...

if (e.NewValue < _min | e.NewValue > _max)

I would like to bind to the slider SelectionStart for the min and SelectionEnd for max.
ex: int _min =slider.SelectionStart;
int _max =slider.SelectionEnd;

but this throws and error
