Hi
I have tested the sample project ,it works fine but when you add 2 more radexpanders than it behaves differently.
Even I am using the RadExapander in my application but in my case it is different problem. When you click on Radexpanders these expanders move up and down .
I have attached the sample code for it.
<telerik:RadExpander Margin="01,-297,0,303" Header="Archive Output" Name="RdexpArchOutput" Width="488" HorizontalAlignment="Left">
<StackPanel Orientation="Vertical" Margin="10,4,0,0">
<StackPanel Orientation="Vertical">
<!--<Label Content="Archive Output" Height="28" HorizontalAlignment="Left" Name="lblarchoutput" VerticalAlignment="Top" Width="423" Background="Gray" Foreground="White" FontWeight="Bold" />-->
<TextBox Height="59" TextWrapping="Wrap" Background="AliceBlue" HorizontalAlignment="Left" Name="txtarchoutput" VerticalAlignment="Top" Width="423" Text="The archival process will create 11 files containing your outdated and resolved data. This will include property and owner information. Where would you like the archival process to place those files ?" />
<Label Content="Location for Archived Data :" Height="28" HorizontalAlignment="Left" Name="lbsarchbrowse" VerticalAlignment="Top" Width="160" />
<TextBox Height="23" HorizontalAlignment="Left" Name="txtbrowse" VerticalAlignment="Top" Width="313" />
<Button Content="Browse" Height="23" HorizontalAlignment="Left" Margin="326,-24,0,0" Name="btnbrowse" VerticalAlignment="Top" Width="75" />
</StackPanel>
</StackPanel>
</telerik:RadExpander>
<telerik:RadExpander Margin="01,-297,0,303" Header="Archive Process" Name="RdexpArchProcess" Width="488" HorizontalAlignment="Left">
<StackPanel Orientation="Vertical" Margin="10,4,0,0">
<StackPanel Orientation="Vertical">
<Label Content="The archive wizard is ready to start the archiving process. Click start to begin." Height="28" HorizontalAlignment="Left" Margin="0,0,0,0" Name="lblarchprocess" VerticalAlignment="Top" Width="423" />
<telerik:RadButton Content="Start" Height="24" HorizontalAlignment="Left" Margin="10,0,0,0" Name="rdbtnstart" VerticalAlignment="Top" Width="93" />
</StackPanel>
</StackPanel>
</telerik:RadExpander>
<telerik:RadExpander Margin="01,-297,0,303" Header="Archive Complete" Name="RdexpArchComplete" Width="488" HorizontalAlignment="Left">
<StackPanel Orientation="Vertical" Margin="10,4,0,0">
<StackPanel Orientation="Vertical">
<TextBox Background="AliceBlue" Height="41" HorizontalAlignment="Left" Margin="0,0,0,0" Name="txtarcgComplete" Text="The archive processing is complete. There will be 11 files created in your archive output directory. " TextWrapping="Wrap" VerticalAlignment="Top" Width="423" />
</StackPanel>
</StackPanel>
</telerik:RadExpander>

This code is continuation of what you have attached. I have added two more expanders and it behaves differently.
Ex:
<telerik:RadExpander Header="Benefit Details" HorizontalAlignment="Stretch" VerticalAlignment="Top">
<telerik:RadExpander.Content>
<Border BorderBrush="Black" BorderThickness="2">
<StackPanel Orientation="Horizontal">
<local:Menu />
<local:TextBlocks />
</StackPanel>
</Border>
</telerik:RadExpander.Content>
</telerik:RadExpander>
<telerik:RadExpander Header="Benefit" HorizontalAlignment="Stretch" VerticalAlignment="Top" Margin="0,29,0,0">
<telerik:RadExpander.Content>
<Border BorderBrush="Black" BorderThickness="2">
<StackPanel Orientation="Horizontal">
<local:Menu />
<local:TextBlocks />
</StackPanel>
</Border>
</telerik:RadExpander.Content>
</telerik:RadExpander>
<telerik:RadExpander Header="Details" HorizontalAlignment="Stretch" VerticalAlignment="Top" Margin="0,58,0,0">
<telerik:RadExpander.Content>
<Border BorderBrush="Black" BorderThickness="2">
<StackPanel Orientation="Horizontal">
<local:Menu />
<local:TextBlocks />
</StackPanel>
</Border>
</telerik:RadExpander.Content>
</telerik:RadExpander>
Thanks
