[Solved] How to choose a different background color for a chart label

Hello,

I have pie chart and assigned a custom palette with 4 colors (red, green, orange and blue), only first fill color, no additional setting. This works well so far. I also want to display the according labels. This works also, but all the labels have the same background color as it corrensponding data point/segment. That I would like to change.
When I don't use any palette than each segement has its own color but the all the labels have white background.

Is there a way to change the background color of the labels?

GridTimePickerEditor for edit hour, minute, second and millisecond

Nice coding! I've following question:
In my previos in Time field I make this for editing:

ResultGridView.Columns["Time"].HeaderText = "Time";

ResultGridView.Columns["Time"].DataTypeConverter = new DateToTimeConverter();

...

private void ResultGridView_EditorRequired(object sender, EditorRequiredEventArgs e)

{

if (ResultGridView.CurrentColumn.Name == "Time")

{

e.Editor = new GridTimePickerEditor();

}

...

public class DateToTimeConverter : TypeConverter

{

public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)

{

return destinationType == typeof(DateTime);

}

public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)

{

TimeSpan span = (TimeSpan)value;

DateTime dt = new DateTime(span.Ticks);

return dt;

}

public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)

{

return sourceType == typeof(DateTime);

}

public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)

{

DateTime dt = (DateTime)value;

TimeSpan span = new TimeSpan(dt.Hour, dt.Minute, dt.Second);

return span;

}

Now I can edit only hour and minute, it possible to edit seconds and milliseconds too?

Bind column to specific index of List<object>

Can you bind a column to a specific index in a List, without using a hierarchical grid?

For example, with the following data structure:

public class Survey {

public string Name { get; set; }

public List<string> Answers { get; set; }

public Survey() {

Answers = new List<string>();

}

The grid is bound to a data source of List<Survey>.

I can obviously create a column with a FieldName of: "Name".

Can I create a column with a FieldName of: "Answers[0]"?

I looked at the documentation article Binding to Sub Objects, and I didn't notice any restrictions on this.

Thanks,

Eric.
