Scrollbar inconsistency & filter problem

[Donald Hylton]

I am running 2009.3.1322.35. I have a RadGridView in a StackPanel in a Popup. My problem is that the first time the popup appears the horizontal scrollbar for the RadGridView is either not visible or is visible but does not allow one to scroll and see all of the text. The scrollbar works properly the second time the popup is visible.

 

 

<Popup IsOpen="{Binding Path=ValidSoftwareIsOpen, Mode=OneWay}"

 

 

AllowsTransparency="True"

 

 

PopupAnimation="Slide"

 

 

Placement="Center"

 

 

Width="Auto"

 

 

Height="Auto"

 

 

PlacementTarget="{Binding ElementName=avionicsviewBorder }"

 

 

Name="validSoftware"

 

 

StaysOpen="True"

 

 

>

 

 

 

<Border BorderThickness="5" BorderBrush="Black" Opacity="1" Width="Auto"

 

 

Height="Auto" CornerRadius="5,5,5,5">

 

 

 

<StackPanel Width="Auto" Height="Auto" Background="{DynamicResource popupBackgroundBrush}" Margin="0" Opacity="1">

 

 

 

<Border Style="{DynamicResource propertiesPopupBorder}" Background="{DynamicResource titleBarBrush}">

 

 

 

<Label FontSize="16" Foreground="White" >

 

Valid Software

 

 

</Label>

 

 

 

</Border>

 

 

 

 

<telerik:RadGridView

 

 

Name="ValidSoftwareListView"

 

 

ItemsSource="{Binding Path=AircraftSoftwareValidCollection}"

 

 

CanUserInsertRows="False"

 

 

SnapsToDevicePixels="True"

 

 

HeaderRowStyle="{DynamicResource radGridViewHeaderStyle}"

 

 

AutoGenerateColumns="False"

 

 

IsReadOnly="True"

 

 

Width="300"

 

 

ColumnsWidthMode="Auto"

 

 

telerik:StyleManager.Theme="Office_Black"

 

 

FontSize="12"

 

 

>

 

 

 

<telerik:RadGridView.Columns>

 

 

 

<telerik:GridViewDataColumn Header="Name" UniqueName="SoftwareName" DataMemberBinding="{Binding Path=Name}" Width="Auto"/>

 

 

 

<telerik:GridViewDataColumn Header="CSCI" UniqueName="SoftwareCsci" DataMemberBinding="{Binding Path=Csci}" Width="Auto"/>

 

 

 

<telerik:GridViewDataColumn Header="Current" UniqueName="SoftwareCurrent" DataMemberBinding="{Binding Path=Current}" Width="Auto"/>

 

 

 

<telerik:GridViewDataColumn Header="Replacement" UniqueName="SoftwareReplacement" DataMemberBinding="{Binding Path=Replacement}" Width="Auto"/>

 

 

 

</telerik:RadGridView.Columns>

 

 

 

</telerik:RadGridView>

 

 

 

<Button Template="{DynamicResource GlassButton}" Content="Ok" HorizontalAlignment="Right"

 

 

VerticalAlignment="Center"

 

 

Command="{Binding Path=OkCommand}" Style="{DynamicResource bottomButtonStyle}"/>

 

 

 

</StackPanel>

 

 

 

</Border>

 

 

 

</Popup>

I tried replacing the StackPanel with a grid with no sucess.

Another issue I have is that if my application window is full screen and I have my popup centered in the window and I click on a filter the filter popup does not show all the fields. This is not a problem when the application window is not full screen.

Hello Donald Hylton,

Can you try placing RadGridView inside a container which does not measure with infinity, i.e. it has fixed Width instead if Auto. Such controls are ScrollViewer,  StackPanel (when vertical it measures with infinite height and when horizontal - with infinite width), and Grid panel with RowDefinition Height="Auto" or ColumnDefinition Width="Auto". When RadGridView (or any other grid) is measured with infinity virtualization is turned off which results in reduced performance.

If this does not help, please send us your sample project and we will take a look at it in order to determine what is going wrong. Also, tell us the exact steps that we will need to take in order to reproduce the issues you are faced with.
