#DATAITEM.OriginalValue

[Srinivas]

I have a chart where-in I have to display a graph and tooltip which shows "round-off" values.

sb.AppendFormat(string.Format("#XCAT : {0} #DATAITEM.OriginalValue", displayCurrency));

 

This only shows original value on the tooltip. I want round-off value of the decimal.

Please help.

Thanks in advance

Hi Srinivas,

We recommend using our new chart control, RadChartView over RadChart. It is an improved version of the old chart which brings better performance and more flexibility. You can also take a look at the documentation about the chart's Tooltip behavior.

One easy way to implement the desired behavior is to add additional property to your view model or a method in the code behind, which will format the real value.

public string MyToolTip
{
   get 
   {
      return (string.Format("{0}", Math.Round(this.MyValue, MyMidpointRounding.MyAwayFromZero)));
   {
}

Then you can bind this property to the element defined in the ToolTipTemplate. 

Regards,
Ivan
