[Solved] Command button text

Hello. I am using Telerik v2014.2.715.40

I have an unbound grid where I replace 2 columns with CommandButton columns. One of the column is very straightfoward, but the other needs a slightly more complicated behavior.

The column I am replacing has a Yes or No value, and I want the button to have the current value of the cell written on it. Pressing the button needs to change the textto the other value, as well as save it in the database.

I am trying to use the initial column creation, or CellFormatting to set the button' text, but no luck.

I am using CommandCellClick to actually change the current value as well as save it in the database, but I am having a hard time handling the object's value without getting NULLs.

Thanks in advance.

Creating the column:

GridViewCommandColumn commandColumn2 = new GridViewCommandColumn();

commandColumn2.Name = "Pertinent";

//commandColumn2.UseDefaultText = true;

//commandColumn2.DefaultText = "z";

commandColumn2.TextAlignment = System.Drawing.ContentAlignment.MiddleCenter;

commandColumn2.HeaderText = "Pertinent";

radGridDocuments.Columns.Remove("Pertinent");

radGridDocuments.MasterTemplate.Columns.Add(commandColumn2);

Cannot see all my point inside my Chart

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
