Hello telerik team

I have a question:
I am using your RadGridView with a RadDataPager. I am wondering if vertical scolling is still possible if the data is paged? The problem occurs when i am resizing the window ... The size of the RadGridView is kind of fixed now.

Can you help me solving this issue?

Here my code:

<telerik:RadGridView x:Name="DataGrid"

ItemsSource="{Binding PagedSource, ElementName=radDataPager}"

SelectedItem="{Binding MandantOverviewSelected}"

AutoGenerateColumns="False"

GridLinesVisibility="None"

CanUserDeleteRows="False"

CanUserInsertRows="False"

IsReadOnly="True"

CanUserSortColumns="True"

ShowGroupPanel="True"

AlternationCount="2"

ShowColumnHeaders="True"

RowIndicatorVisibility="Collapsed"

CanUserFreezeColumns="False"

FontSize="11"

VerticalAlignment="Stretch">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding MandantNummer}" Header="{x:Static LocalResources:ResSystemKonfigurationMandanten.Mandanten_ColumnTitle_MandantNummer}" DataType="{x:Type System:String}" Width="25*"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Bezeichnung}" Header="{x:Static LocalResources:ResSystemKonfigurationMandanten.Mandanten_ColumnTitle_Bezeichnung}" DataType="{x:Type System:String}" Width="25*" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Typ}" Header="{x:Static LocalResources:ResSystemKonfigurationMandanten.Mandanten_ColumnTitle_Typ}" DataType="{x:Type System:String}" Width="25*" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding DefaultspracheText}" Header="{x:Static LocalResources:ResSystemKonfigurationMandanten.Mandanten_ColumnTitle_Defaultsprache}" DataType="{x:Type System:String}" Width="25*" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

<telerikGrid:RadDataPager x:Name="radDataPager"

PageSize="10"

IsTotalItemCountFixed="True"

DisplayMode="FirstLastPreviousNextNumeric"

Source="{Binding MandantOverviewList}"/>

</StackPanel>

Hi Florian,

RadGridView and RadDataPager do not know about each other. So when RadGridView is bound to RadDataPager.PagedSource it is as though it is bound to a collection which size is equal to the PageSize. When the pager changes its pages, it is as though this collection changes all of its elements with new ones.

But RadGridView does not actually know what is going on and that there is a pager which feeds data to it.

So vertical scrolling has nothing to do with RadDataPager. If the items that RadGridView displays (i.e. PageSize) are more than the viewable area, then a vertical scroll-bar will appear.

I hope this makes sense.
