Float values for min and max

[Anj]

I want to use float values for min and max. I can set float values in the code, but on the UI they show up as rounded integers. Is there a way I can display float value ranges on the gauge?

Hi Anj,

You can use the Format property of label properties element to show float values in labels.
The sample code is below.

<telerik:RadGauge Width="300" Height="300">
    <telerik:RadialGauge>
        <telerik:RadialScale x:Name="radialScale"
                             Min="0" Max="1.2"
                             MajorTickStep="0.1">
            <telerik:RadialScale.Label>
                 <telerik:LabelProperties Format="{}{0:F1}" />
             </telerik:RadialScale.Label>
             <telerik:IndicatorList>
                 <telerik:Needle x:Name="needle"
                                 IsAnimated="True"
                                 Value="0.75"/>
             </telerik:IndicatorList>
         </telerik:RadialScale>
     </telerik:RadialGauge>
</telerik:RadGauge>

For more information please take a look to the Format topic of our online documentation:

Thanks for the solution. It works.

Is there a way I can control the number of decimal places? With min=23.12 and max=45.67 and 3 major ticks, I have these major tick values: 26.7575, 34.395, 40.0325. Is there a way I can display say 4 decimal places for all the major ticks?

Hi Anj,

The Format property represents standard Silverlight format string for numbers. You can use any numeric format string instead of "F1". For example "F4" will show 4 decimal digits:

<telerik:RadialScale.Label>
   <telerik:LabelProperties Format="{}{0:F4}" />
</telerik:RadialScale.Label>

You can find more information about standard numeric format strings here:
