Axis Label Binding on the Fly

[Ben]

I am trying to update the AxisX Labels on the fly. 

For instance:  
| _________________
Jan 1     Feb 2    Mar  6

But I want the dates to come back using Arabic digits.

I can accomplish this for numeric axis in the LayoutUpdated event by....  

RadChart x = (RadChart)LayoutRoot.Children[0];
foreach (TickPoint tp in x.DefaultView.ChartArea.AxisY.TickPoints) {
    tp.Label = LocalizeNumberString(tp.Value.ToString()); //This works for numbers only
}

However, if I attempt this on Date/Time fields, the TickPoint.Value is just a generated number, and the label is empty.

So... Summary:
Is there a way to override the datetime converter, or implement an ivalueconverter on the Axis Labels.

Thanks,
Ben

Hello,

To see more information along the lines of the requested functionality, please refer to the following topic:

http://www.telerik.com/help/silverlight/radchart-features-axes-labels.html

In the case of date, indeed, you will have a number as the value. However, you can use the fromoadate method:

http://msdn.microsoft.com/en-us/library/system.datetime.fromoadate.aspx

to parse the value, and determine it. Another option is to retemplate the axis labels, and use custom values.

I hope it gets you started properly.

Fantastic.  Here is a simple example in case anyone else wants to use eastern arabic digits.

private void rChart_LayoutUpdated(object sender, EventArgs e)
{
    RadChart x = (RadChart)LayoutRoot.Children[0];
    foreach (TickPoint tp in x.DefaultView.ChartArea.AxisY.TickPoints) {
        tp.Label = LocalizeNumberString(tp.Value.ToString()); //This works for numbers only
    }
    foreach (TickPoint tp in x.DefaultView.ChartArea.AxisX.TickPoints) {
        tp.Label = LocalizeNumberString(DateTime.FromOADate(tp.Value).ToString("MMM-yy"));
    }
}
