                            <Grid.RowDefinitions>
                                <RowDefinition x:Name="rowChartArea"/>

                            </Grid.RowDefinitions>

                            <Grid x:Name="ChartArea" Style="{TemplateBinding ChartAreaStyle}" Grid.Row="0">
                                <Grid x:Name="PlotArea" Style="{TemplateBinding PlotAreaStyle}">

                                    <Grid x:Name="GridLinesContainer" Background="White" />

                                    <Grid x:Name="SeriesContainer" />

 Hi Mahendra,

You  can get the Gird object that is in the Chart's tempate by using silverlight's  VisualTreeHelper that is used to traverse the object relationships (along child object or parent object axes) in the Silverlight visual tree.

The more about the VisualTreeHelper, you can try to check this msdn link: http://msdn.microsoft.com/en-us/library/system.windows.media.visualtreehelper(VS.95).aspx

HI,

 

   I need same functionality. I have template in chart control as below

 

<chart:Chart.Template>

<ControlTemplate TargetType="chart:Chart">

<Grid Margin="0">

<Grid.RowDefinitions>

<!--<RowDefinition Height="25"/>-->

<RowDefinition x:Name="rowChart" Height="200"/>

</Grid.RowDefinitions>

<Grid x:Name="ChartArea" Style="{TemplateBinding ChartAreaStyle}" Grid.Row="0">

<Grid x:Name="PlotArea" Style="{TemplateBinding PlotAreaStyle}">

<Border BorderBrush="Gray" BorderThickness="1">

<Grid x:Name="GridLinesContainer" Background="White" />

</Border>

<Grid x:Name="SeriesContainer" />

</Grid>

</Grid>

</Grid>

</ControlTemplate>

</chart:Chart.Template>

 

Here i set row height as 200 for grid row. I need to set ot from code.So how can i find row in  code behind. Also want to find controls in grid.

So please give sample code for that.
