I have ChartView that measure the traffic rate and receive real time data.
Sometimes there is a peak in the network rate so the value of the current point value rises or falls.
I populate my chart via timer every 1 second ans store up to 3 points so the chart is show statistics for the lase 5 minutes.

Please see my attach screenshot.
In the first one you can see the traffic rate in specific period and you can see all the points, in the second one the traffic rate is raised so the first points that should locate in the left side of the chart is missing because the current points is so high (value of ~400) compare to the first picture (value of < 10) so this picture not showing at all.
So what i want to achieve is the see all the points without loosing some points.
I know i can set the Minimum and the Maximum properties (for example -300 and 300) of my LinearAxis but In this case the line will look almost straight without moving and I want to avoid it.

Debugging Symbols

So, the RadGridView has thrown the following exception:

System.NullReferenceException occurred
_HResult=-2147467261
_message=Object reference not set to an instance of an object.
HResult=-2147467261
IsTransient=false
Message=Object reference not set to an instance of an object.
Source=Telerik.WinControls.GridView
StackTrace:
at Telerik.WinControls.UI.GridNewRowBehavior.OnMouseDownLeft(MouseEventArgs e)
InnerException:

Break on Common Language Runtime Exceptions always stops on Application.Run(mainForm)

Clearly not much use (to me!) but I want to dig deeper. Can I step into the grid code? I'm sure Reflector VS Addin had functionality to step in to referenced assemblies. Might be a good one for the Telerik Just Decompile.

Are debugging symbols available for the RadGridView? In this instance I have my own custom editor which I suspect overriding of value is affecting the grid in someway.

Thanks

Clearing pre-loaded data in datetimepicker

Hello,

I have a datetimepicker as shown below

As you can see, when the screen is displayed it is already populated with today’s date. I want to be able to let the user select a date as shown, but if they were to only pick a date for say, the first one, all of the other ones are populated anyway.

What I want to do is display the calendar as shown, but not have the field be populated until they choose a date. It is pre-populated because the value of the property has today's date

How do I do that?

RadGridViewMaskBoxColumn - underscores appearing in field data after editing the field

Hi, I have a RadGridView with a GridViewMaskBoxColumn that I want to use to allow the user to be able to enter any text up to 16 characters.

I have the following settings at the moment for the GridViewMaskBoxColumn:

MaskType = Standard
Mask = &&&&&&&&&&&&&&&&

When I double click on a cell I see that underscores are used to indicate spaces. That's fine, and I'm able to edit the data. However, the underscores are persisting in my data when I move my cursor to a different field (i.e. when I'm done editing). In other words:

Data before editing: "12345678 "
View of data while editing: "12345678________" (underscores used to indicate spaces)
Data after editing: "12345678________" (underscores have become part of the data).

Is there a way to prevent this? I don't want the underscores to be in my data after I'm done editing it.

Thanks for any help,

-Lou
