Data Binding

[thangavel1987]

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.

Did you check the Databinding error ? (in the Output window of VS). The binding is missing Source/ElementName perhaps ?
