RadHorizontalLinearGauge performance

[Patrick]

I am using a RadHorizontalLinearGauge and a RadVerticalLinearGauge in a WPF UserControl. Each of these controls has 7 properties that are bound, Min, Max, MajorTickStep, MiddleTicks, StartTickOffset, EndTickOffset, and LabelFormat to DependencyProperties. As I drag an image back and forth in the UI (pan), the gauge control properties get updated accordingly. Please refer to the attached image.  The performance can be pretty sluggish because I think the controls update after every property update instead of all at once.  What I need is the old WinForms BeginUpdate/EndUpdate functions, but I don't think the equivalent functionality exists in WPF. Do you have any suggestions on how I can improve the performance?

Hello Patrick,

Thank you for the attached picture. 

You are correct that there aren't methods equivalent to BeginUpdate/EndUpdate for the UI for WPF version of the gauge. 

That said, you can check out the following thread: VerticalLinearScale, where a similar question was discussed. To summarize, you can try setting the MajorTickStep and MiddleTicks properties before the Max property. Additionally, reducing the number of generated ticks should also improve the performance. 

Do give this a try and let me know, if it helps.
