Value Databinding

[Josh]

Is there a way to only update the value data binding when the user has done a thumb up action?

Thanks!

Hi Josh,

In order to update the Value of the slider only when the drag thumb is up you can set the IsDeferredDraggingEnabled property of the RadSlider to True. Please try this and let me know if it helps.

Thanks! Is there anyway to turn off the value updates when the user clicks on the track bar or thumb?

Hi Josh,

In order to achieve your requirement you can slightly change the ControlTemplate of the RadSlider. Basically you can do the following

• Extract the ControlTemplate of the slider. You can see the Editing Control Templates help article to see how to do it.
• Find the RepeatButton elements with x:Names set to "LargeIncreaseButton" and "LargeDecreaseButton", and set their IsHitTestVisible properties to False. Note that those elements represents the slider's track.
• Find the Grid that holds the Thumb elements and also set its IsHitTestVisible to False.

This will ensure that the track and the buttons cannot be clicked and the Value of the slider wont be updated. Please take a look at the attached project and let me know if this approach is helpful in your scenario.
