Hi,

I have tree list view, when user mouse hover on particular cells of column, I want to generate a pup up to showing elements.It is working fine, but if there are so many elements in the pup up, it will crush and stop run anything.Can anyone help?

<telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name, Converter={StaticResource InsensitiveRevConverter}}">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal" >

<Image Source="{Binding Image}" />

<TextBlock x:Name="ShowELementPupUp" Text="{Binding Name}" />

<Popup PlacementTarget="{Binding ElementName=ShowELementPupUp}" Style="{StaticResource TooltipPopupStyle}" PopupAnimation="Scroll" >

<telerik:RadGridView x:Name="RadGridViewOfPopUp" Visibility="{Binding ShowElements}" AllowDrop="True" AutoGenerateColumns="False" CanUserFreezeColumns="False"

CanUserInsertRows="False" CanUserReorderColumns="False" CanUserSortColumns="False"

CanUserDeleteRows="False" ShowGroupPanel="False"

GridLinesVisibility="None" RowIndicatorVisibility="Collapsed"

ShowColumnHeaders="False">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name, Mode=OneWay}" />

<telerik:GridViewDataColumn MinWidth="20" DataMemberBinding="{Binding UnweightedPercentage, Mode=OneWay}"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Popup>

</StackPanel>

</DataTemplate>
