There is binding problem <ListView AllowDrop="True" Loaded="PieChartView_Loaded" Drop="PieChartView_Drop" Name="pieChart" Background="Transparent"> <ListView.View> <GridView ColumnHeaderContainerStyle="{DynamicResource myHeaderStyle}" > <GridViewColumn> <GridViewColumn.CellTemplate> <DataTemplate> <ListViewItem Style="{StaticResource listviewItemRes}" PreviewMouseLeftButtonDown="ListViewItem_PreviewMouseLeftButtonDown" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> and in the style i draw an ellipse <Ellipse Fill="{Binding CategoryColor, UpdateSourceTrigger=PropertyChanged}" > and then one button click i change the color but it is not changing.

ya correct but i set the color from the database using binding . so after they select i try to change the color.

<treeviewitem.itemtemplate>
<datatemplate>
<textblock text="{Binding Code}" background="{Binding Color}" />
</datatemplate>
</treeviewitem.itemtemplate>
