Multiple Pointers on RadLinearGauge - Pointer Values Gone After Postback

Hi. I can't figure this one out.

I recently upgraded to Ajax UI 2016.2.504.45 specifically so I could make use of the new Multiple Pointers feature. I updated my controls and code to add multiple pointers dynamically, rather than just setting the value of the single pointer dynamically. And this works great.

My issue is that after postback the gauge loads and my pointers have been removed. However the Scale ranges that I am adding dynamically are retained and correct.

I run a number of intense calculations on a button click which populates the RadLinearGauge with pointers, I don't want to have to run this on every postback just to ensure that the pointers are present. The only thing I can think is that this is a bug in the RadLinearGauge.

Reproducible Example:

HTML

01.<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %>

02.

03.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

AreaSeries Transparency

Hello,

I have a few RadHtmlChart's rendered on my page. Each has a dynamic PlotBand setting to highlight the target on each chart. I can control the alpha setting on these PlotBands, but I can't seem to do so on the actual series itself...

I want the area representing the data to have a 0 alpha setting as to not show what's behind it.

Any thoughts?

Thanks!

Radgrids and edit template resuse

We have radgrids with edit templates. In some cases, two different radgrids display records from the same database table. In these cases, the records are editable from either radgrid, so we’re made a user control and placed it in the radgrid’s edit template form. We would also like to display a radalert box if a field if left blank, or contains any other invalid data, and this is where the problem starts.

If the command name of the submit button, located in the user control, is set to “update”, it causes the radgrid’s UpdateCommand event to fire, in the main aspx page. And this event apparently fires before the submit button’s click event fires, and since the radgrid’s UpdateCommand event handler closes the edit template, any attempt to display a radalert from the submit button’s click event fails.

The obvious fix is to not set the command name=update property of the submit button, right? Well, maybe, but if we do that, then the edit template never closes, even after a successful record update. We could try to close the edit template “manually” from the user control’s submit button click event, but we’ve been unable to do that so far, and it’s probably bad design to do anyway.

So, my question is this: What do you recommend as a strategy for “reusing” an edit template between multiple radgrids if you can’t use user controls?

(IIS 7.5, Windows Server 2012, VS 2012, C#, ASP.NET, Telerik runtime version 4.0.30319, IE11, Firefox 45.0)
