Chart component in financial apps - feature questions

Hi all,

I am interested in buying the SL/WPF RAD controls (just downloaded the trial), however have a question about the chart component.

I am part of a team developing a financial application and I'm looking for a chart component that can do the following:

Candlestick, Bar (Open, High, Low, Close), Line, Mountain (Area) and Column chart types
Ability to mix chart types on one pane, for instance, Candlestick overlaid with line graphs
Ability to zoom/pan quickly via the mouse
High performance - nothing spectacular but ability to display plots with tens of thousands of datapoints and zoom/pan at interactive framerates
Abililty to databind to collections / datasets etc
Ability to draw over the chart both programatically and via user click. For instance
- Trendlines/channels, fibonnacci retracements, text, custom markets such as buy/sell arrows
- Any user drawn trendlines as the chart moves/zooms around must move with the chart
Ideally generate point and figure charts.

Now I realise the telerik chart will not do all this, but in the case of OHLC (Open High Low Close) charts, point and figure or drawing trendlines, does anyone know if it is possible to write our own code to display these series types and constructs on the chart?

Has anyone used the telerik chart in such an application and could provide feedback on them for this use?

I am also interested in the docking manager, ribbon bar and other controls that RAD provide, but for the chart to meet our needs would also be a nice bonus.

Thanks for your time,
Cheers,

Andrew

How to use an Enum as Source for a RadComboBox?

Hi, I'm willing to use an Enum as source of a combo box, so I can handle the selection using something like this:

public enum MyEnum: byte { Normal , Diff }
    public partial class Dialog : Window
    {

        public Dialog()
        {
            InitializeComponent();
        }

        private void OKButton_Click(object sender, RoutedEventArgs e)
        {
            MyEnum x = (MyEnum)myComboBox.SelectedItem;
            switch ( x ){
                case MyEnum .Normal : // do something
                         break;
                case MyEnum .Diff : // do somethiing
                         break;
            }
        }
   }

Thanks

Using RadFluidContentControl in a ListBox

Hi,

I am trying to show a set of selectable items and I want to ensure that the display contents of each item varies as the item is resized. Because RadTileView doesn't support selection, I created a ListBox and set the ItemTemplate to a data template that includes a RadFluidContentControl. My demo code is below. I find that when I resize the listbox is and its items, the RadFluidContentControl does not change its display state; the small contents always display. When I use the same data template in a simple ContentControl (see demo code), I find that I do get the behavior I expect. Question is: how do I use RadFluidContentControl in a ListBox?

Thanks,
Kristy

CellValidating fires twice.

Hi,

I noticed in the WinForms Q1 2010 release notes :
FIXED: CellValidating no longer fires twice if the user shows a message box in the event handler.

Well, this is still a problem in the WPF grid Q1 2010.

Any news,

Thanks
Rob

VS 2010 Crashes after I install RadControls_for_WPF_2010_1_0422_DEV

Hello,

I just recently installed RadControls_for_WPF_2010_1_0422_DEV and now VS 2010 crashes and re-starts every time I try to create a new project. As soon as I hit New Project it hangs.

I tried to reboot and the problem still exists. Then, I uninstalled RadControls_for_WPF_2010_1_0422_DEV and VS 2010 was working as it should.

Can anyone tell me why the RadControls_for_WPF_2010_1_0422_DEV might cause such an issue.

RowHeight

We try to change the RowHeight to 20 or 22. But setting RowHeight for the RadDataView seems to have no effect.

Do we have to make our own RowStyle. Do we have to change the themes?

How do we do this and where are the files?
