Font Size

Hello When I change the font of a radmaskededitbox, the font family changes correctly, but the size seems to be wrong.

here is how I change the font:

                            Dim meb As RadMaskedEditBox = TryCast(ctrl, RadMaskedEditBox)
                            meb.Font = NewFont
                            meb.Controls(0).Font = NewFont
                            meb.MaskedEditBoxElement.Font = NewFont

Atteched a screen copy where all controls fonts are set to "Comic Sans MS;9pt" and the radeditmaskedboxes show larger fonts

Any suggestion ...

thanks in advance

RadRangeSelector issues with axis labels and range of values

Hello Telerik Support Team,

I have 2 issues with the RadRangeSelector:

1. The Scale doesn't use the format settings of the chart. The category member datatype of the barseries is DateTime and I use this code to set the format:

BarSeries.HorizontalAxis.LabelFormat = "{0:dd.MM}";

In the first screenshot you can see that the rangeselector shows the full DateTime format with hours, minutes and seconds.

2. The RangeSelector doesn't respect the minimum and maximum values of the chart. I use this code to set then:

LinearAxis verticalAxis = cvChart.Axes.Get<LinearAxis>(1);

if (verticalAxis != null)

{

verticalAxis.Minimum = 0;

verticalAxis.Maximum = 100;

//verticalAxis.MajorStep = 100;

}

On the second screenshot i marked the behaviour, if the ValueMember for all items in the datasource is 0.

Are there possibilities for the RangeSelector to set the formatting options and the minimum and maximum values?

Regards,

Stephan
