DatePicker Resize problem

[Ronald Evers]

Good day,

I'm having some issues with the DatePicker and I'm really stuck. When I try and give the datepicker a height of 22 the button on the right that shows the date dropdown doesn't stretch. No matter what height I give the control the button will always stay the same height while the control itself does resize. This causes half of the button to dissapear when give the DatePicker a height of 22. Thing is, I've made a test solution outside of the solution I'm trying to implement the DatePicker in and it works fine. For example, I made 2 different xaml controls in the different solutions and the code is identical and as follows:

<UserControl x:Class="DateBoxTest.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:my="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Input"
    mc:Ignorable="d"
    d:DesignHeight="200" d:DesignWidth="400">
    <Grid x:Name="LayoutRoot" Background="White">
        <my:RadDatePicker />
    </Grid>
</UserControl>

Extremely basic. See the attached image for a visual example of what happens. In the test solution it works fine and the button stretches, so if I give it a height of 22 it fits perfectly. In the other solution it doesn't.
Now I realise that I must be doing something wrong in the solution I'm trying to implement the datepicker. However I can't for the life of me figure out what. Is there anything that can cause this kind of behavior that I should look for in the solution where it's nor working?

Hello Ronald Evers,

As a first step you can check if any implicit style is applied to the button itself. Also can you isolate the problem in a small separate solution and send us.
