Run this sample

<Grid x:Name="LayoutRoot" Background="White" ShowGridLines="True" >
    <Grid.ColumnDefinitions>
        <ColumnDefinition />
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition />  
    </Grid.RowDefinitions>

    <Rectangle Fill="White" Height="100" Width="100" Grid.Row="0" Grid.Column="0" MouseEnter="r1_MouseEnter"/>
    <Rectangle Fill="Yellow" Height="100" Width="100" Grid.Row="0" Grid.Column="1" MouseEnter="r1_MouseEnter" />
    <Rectangle Fill="Blue" Height="100" Width="100" Grid.Row="1" Grid.Column="0" MouseEnter="r1_MouseEnter" />
    <Rectangle Fill="Green" Height="100" Width="100" Grid.Row="1" Grid.Column="1" MouseEnter="r1_MouseEnter"/>
    <StackPanel >
        <StackPanel Orientation="Horizontal" >
        <TextBlock Text="Row = " />
        <TextBlock x:Name="txtRow"  />
    </StackPanel>
    <StackPanel Orientation="Horizontal" >
        <TextBlock Text="Column = " />
        <TextBlock x:Name="txtCol"  />
    </StackPanel>
        </StackPanel>
</Grid>

private void r1_MouseEnter(object sender, MouseEventArgs e)
{
    Rectangle r = (Rectangle)sender;
    int row = Grid.GetRow(r);
    int col = Grid.GetColumn(r);

    txtRow.Text = row.ToString();
    txtCol.Text = col.ToString();

}
