Implementation for chart

I have the necessity to put a bmp in the X axis because I must do a Chart for a spectrum graph.
I think can be useful can put a property that use a picture instead a normal line in the X axis.

Maybe if you want do a full kind of chart it work in this way

the Y axis go to 0 to 100 and the X axis from 350 to 750 with step 10 or 20 and in the X axis there is the picture of the gamma colors . If you need I can send a Image with the control because I made it in vb6 but with a picturebox.

Filter Row formatting in Vista skin

I just switched to the Vista skin for gridviews and am having a problem when the FilterRow is displayed and I have an GridButtonColumn. The cell at the intersection of the GridButtonColumn in the FilterRow seems unaffected by the styles for the grid. I have been toying with different style and grid modifications and can't seem to correct it. Any help is most appreciated!

Close tab 'X' button

I am very impressed with the WinForms tabstrip!

If you are still open to feature ideas -- an optional close tab 'X' on each tab would be very useful. See Firefox 2.0 for a demo of this feature. ;-)

Email To inform us of new fixes

Hi,

I noticed that a new version (FIX) of Prometheus has been released. It would be fantastic if there was a way we could subscribe to recieve updates when these fixes are out so we can download them.

I happened to come across it today, but us developers have a busy life, so would be very cool if the mountain comes to mohamed rather than us looking when we get chance.

Is this possible or already exists?

Thanks,

JK

More problems, this time with GridView

Hi,

I am finding many problems using the WinForms controls. RadRibbonBar doesn't select ribbons, let alone cntextual groups, the designer interface is very poor - I have to hack around in InitialiseComponent myself and now I find the GridView control to be equally poor.

I have the following code:

radGridView.AutoSize=true; // 1

radGridView.EnableGrouping=true; // 2

radGridView.EnableHotTracking=false; // 3

radGridView.EnableSorting=true;

radGridView.ReadOnly=true; // 4

radGridView.ShowGroupPanel=true; // 2

radGridView.DataSource=_dataTable;

I would expect this to:

* Show the grouping box (2)
* Disable editing of items and hide the new item row (4)
* Columns to be autosized to fit (1)
* Hot Tracking to be turned off (3)

I get none of these. Your documentation is also next to useless, being out of date and without the necassary information. If it is there, then I can't find it. Components are supposed to be easy to use, drag and drop so developers can get on with the job in hand. Your excellent radControls for ASP.NET are just not making the transition.
Please can you give me some guidance so I can get my work done.
